This can be achieved by having the role of Global Admin or possessing an AD Connect sync account. Alternatively, the Hybrid Identity Administrator role would suffice, as it grants the ability to manage AD Connect and establish new sync accounts. -- Presence of a **hybrid account** is essential. This account must be amenable to modification with the victim account's details and should also be accessible for authentication. -- Identification of a **target victim account** within Active Directory is a necessity. Although the attack can be executed on any account already synchronized, the Azure AD tenant must not have replicated on-premises security identifiers, necessitating the modification of an unsynchronized account to procure the ticket. - - Additionally, this account should possess domain admin equivalent privileges but must not be a member of typical AD administrator groups to avoid the generation of invalid TGTs by the AzureAD RODC. - - The most suitable target is the **Active Directory account utilized by the AD Connect Sync service**. This account is not synchronized with Azure AD, leaving its SID as a viable target, and it inherently holds Domain Admin equivalent privileges due to its role in synchronizing password hashes (assuming Password Hash Sync is active). For domains with express installation, this account is prefixed with **MSOL\_**. For other instances, the account can be pinpointed by enumerating all accounts endowed with Directory Replication privileges on the domain object. +- Sposobnost da se menjaju nalozi putem Synchronization API je ključna. To se može postići imajući ulogu Global Admin ili posedujući AD Connect sinhronizovani nalog. Alternativno, uloga Hibridnog identitetskog administratora bi bila dovoljna, jer omogućava upravljanje AD Connect-om i uspostavljanje novih sinhronizovanih naloga. +- Prisutnost **hibridnog naloga** je neophodna. Ovaj nalog mora biti podložan izmeni sa podacima žrtvovanog naloga i takođe bi trebao biti dostupan za autentifikaciju. +- Identifikacija **ciljnog naloga žrtve** unutar Active Directory je neophodna. Iako se napad može izvršiti na bilo kom nalogu koji je već sinhronizovan, Azure AD tenant ne sme imati replicirane on-premises identifikatore bezbednosti, što zahteva izmenu nesinhronizovanog naloga kako bi se dobila karta. +- Pored toga, ovaj nalog bi trebao imati privilegije jednake privilegijama domain admin-a, ali ne sme biti član tipičnih AD administratorskih grupa kako bi se izbeglo generisanje nevažećih TGT-ova od strane AzureAD RODC-a. +- Najpogodniji cilj je **Active Directory nalog koji koristi AD Connect Sync servis**. Ovaj nalog nije sinhronizovan sa Azure AD, ostavljajući njegov SID kao mogući cilj, i inherentno ima privilegije jednake privilegijama domain admin-a zbog svoje uloge u sinhronizaciji hešova lozinki (pod pretpostavkom da je Password Hash Sync aktivan). Za domene sa ekspresnom instalacijom, ovaj nalog je prefiksiran sa **MSOL\_**. Za druge instance, nalog se može identifikovati prebrojavanjem svih naloga koji imaju privilegije replikacije direktorijuma na objektu domena. -### The full attack +### Potpuni napad -Check it in the original post: [https://dirkjanm.io/obtaining-domain-admin-from-azure-ad-via-cloud-kerberos-trust/](https://dirkjanm.io/obtaining-domain-admin-from-azure-ad-via-cloud-kerberos-trust/) +Proverite to u originalnom postu: [https://dirkjanm.io/obtaining-domain-admin-from-azure-ad-via-cloud-kerberos-trust/](https://dirkjanm.io/obtaining-domain-admin-from-azure-ad-via-cloud-kerberos-trust/) {{#include ../../../../banners/hacktricks-training.md}} - - - - diff --git a/src/pentesting-cloud/azure-security/az-lateral-movement-cloud-on-prem/azure-ad-connect-hybrid-identity/az-default-applications.md b/src/pentesting-cloud/azure-security/az-lateral-movement-cloud-on-prem/azure-ad-connect-hybrid-identity/az-default-applications.md index 593b0222a..ddf430501 100644 --- a/src/pentesting-cloud/azure-security/az-lateral-movement-cloud-on-prem/azure-ad-connect-hybrid-identity/az-default-applications.md +++ b/src/pentesting-cloud/azure-security/az-lateral-movement-cloud-on-prem/azure-ad-connect-hybrid-identity/az-default-applications.md @@ -4,10 +4,6 @@ **Check the techinque in:** [**https://dirkjanm.io/azure-ad-privilege-escalation-application-admin/**](https://dirkjanm.io/azure-ad-privilege-escalation-application-admin/)**,** [**https://www.youtube.com/watch?v=JEIR5oGCwdg**](https://www.youtube.com/watch?v=JEIR5oGCwdg) and [**https://www.youtube.com/watch?v=xei8lAPitX8**](https://www.youtube.com/watch?v=xei8lAPitX8) -The blog post discusses a privilege escalation vulnerability in Azure AD, allowing Application Admins or compromised On-Premise Sync Accounts to escalate privileges by assigning credentials to applications.

-1. Initially, an application (Service Provider or SP, such as AWS console or vSphere web client) is accessed by a user. This step might be bypassed, leading the client directly to the IdP (Identity Provider) depending on the specific implementation. -2. Subsequently, the SP identifies the appropriate IdP (e.g., AD FS, Okta) for user authentication. It then crafts a SAML (Security Assertion Markup Language) AuthnRequest and reroutes the client to the chosen IdP. -3. The IdP takes over, authenticating the user. Post-authentication, a SAMLResponse is formulated by the IdP and forwarded to the SP through the user. -4. Finally, the SP evaluates the SAMLResponse.

The **PRT (Primary Refresh Token) is extracted from LSASS** (Local Security Authority Subsystem Service) and stored for subsequent use. -2. The **Session Key is extracted next**. Given that this key is initially issued and then re-encrypted by the local device, it necessitates decryption using a DPAPI masterkey.

Post decryption of the Session Key, the **derived key and context for the PRT are obtained**. These are crucial for the **creation of the PRT cookie**.

For example, if a user's login behavior is unusual compared to their regular pattern, such as logging in from a different country, the system can prompt for additional authentication. -2. **Device Compliance Policy**: This policy can restrict access to Azure services only to devices that are compliant with the organization's security standards. For instance, access could be allowed only from devices that have up-to-date antivirus software or are running a certain operating system version. +1. **Politika rizika prijavljivanja**: Ova politika može biti postavljena da zahteva višefaktorsku autentifikaciju (MFA) kada se otkrije rizik prijavljivanja. Na primer, ako je ponašanje korisnika prilikom prijavljivanja neobično u poređenju sa njihovim redovnim obrascem, kao što je prijavljivanje iz druge zemlje, sistem može zatražiti dodatnu autentifikaciju. +2. **Politika usklađenosti uređaja**: Ova politika može ograničiti pristup Azure uslugama samo na uređaje koji su usklađeni sa bezbednosnim standardima organizacije. Na primer, pristup može biti dozvoljen samo sa uređaja koji imaju ažuriran antivirusni softver ili koji koriste određenu verziju operativnog sistema. -## Conditional Acces Policies Bypasses +## Zaobilaženje politika uslovnog pristupa -It's possible that a conditional access policy is **checking some information that can be easily tampered allowing a bypass of the policy**.

While access keys provide full administrative access to all resources, SAS allows for granular control by specifying permissions (like read or write) and defining an expiration time. +Shared Access Signatures (SAS) su sigurni, vremenski ograničeni URL-ovi koji **dodeljuju specifične dozvole za pristup resursima** u Azure Storage nalogu bez izlaganja pristupnih ključeva naloga. Dok pristupni ključevi pružaju punu administrativnu kontrolu nad svim resursima, SAS omogućava granularnu kontrolu tako što specificira dozvole (kao što su čitanje ili pisanje) i definiše vreme isteka. -#### SAS Types +#### SAS Tipovi -- **User delegation SAS**: This is created from an **Entra ID principal** which will sign the SAS and delegate the permissions from the user to the SAS. It can only be used with **blob and data lake storage** ([docs](https://learn.microsoft.com/en-us/rest/api/storageservices/create-user-delegation-sas)). It's possible to **revoke** all generated user delegated SAS. - - Even if it's possible to generate a delegation SAS with "more" permissions than the ones the user has. However, if the principal doesn't have them, it won't work (no privesc). -- **Service SAS**: This is signed using one of the storage account **access keys**. It can be used to grant access to specific resources in a single storage service. If the key is renewed, the SAS will stop working. -- **Account SAS**: It's also signed with one of the storage account **access keys**. It grants access to resources across a storage account services (Blob, Queue, Table, File) and can include service-level operations. +- **User delegation SAS**: Ovo se kreira iz **Entra ID principal** koji će potpisati SAS i delegirati dozvole od korisnika na SAS. Može se koristiti samo sa **blob i data lake storage** ([docs](https://learn.microsoft.com/en-us/rest/api/storageservices/create-user-delegation-sas)). Moguće je **opozvati** sve generisane korisničke delegirane SAS. +- Čak i ako je moguće generisati delegaciju SAS sa "više" dozvola nego što korisnik ima. Međutim, ako principal nema te dozvole, neće raditi (nema privesc). +- **Service SAS**: Ovo se potpisuje koristeći jedan od pristupnih ključeva **storage** naloga. Može se koristiti za dodeljivanje pristupa specifičnim resursima u jednoj usluzi skladištenja. Ako se ključ obnovi, SAS će prestati da funkcioniše. +- **Account SAS**: Takođe se potpisuje jednim od pristupnih ključeva **storage** naloga. Dodeljuje pristup resursima širom usluga skladištenja naloga (Blob, Queue, Table, File) i može uključivati operacije na nivou usluge. -A SAS URL signed by an **access key** looks like this: +SAS URL potpisan sa **pristupnim ključem** izgleda ovako: - `https://.blob.core.windows.net/newcontainer?sp=r&st=2021-09-26T18:15:21Z&se=2021-10-27T02:14:21Z&spr=https&sv=2021-07-08&sr=c&sig=7S%2BZySOgy4aA3Dk0V1cJyTSIf1cW%2Fu3WFkhHV32%2B4PE%3D` -A SAS URL signed as a **user delegation** looks like this: +SAS URL potpisan kao **user delegation** izgleda ovako: - `https://.blob.core.windows.net/testing-container?sp=r&st=2024-11-22T15:07:40Z&se=2024-11-22T23:07:40Z&skoid=d77c71a1-96e7-483d-bd51-bd753aa66e62&sktid=fdd066e1-ee37-49bc-b08f-d0e152119b04&skt=2024-11-22T15:07:40Z&ske=2024-11-22T23:07:40Z&sks=b&skv=2022-11-02&spr=https&sv=2022-11-02&sr=c&sig=7s5dJyeE6klUNRulUj9TNL0tMj2K7mtxyRc97xbYDqs%3D` -Note some **http params**: +Napomena o nekim **http parametrima**: -- The **`se`** param indicates the **expiration date** of the SAS -- The **`sp`** param indicates the **permissions** of the SAS -- The **`sig`** is the **signature** validating the SAS +- **`se`** parametar označava **datum isteka** SAS-a +- **`sp`** parametar označava **dozvole** SAS-a +- **`sig`** je **potpis** koji validira SAS -#### SAS permissions +#### SAS dozvole -When generating a SAS it's needed to indicate the permissions that it should be granting. Depending on the objet the SAS is being generated over different permissions might be included. For example: +Kada se generiše SAS, potrebno je naznačiti dozvole koje bi trebalo da dodeljuje. U zavisnosti od objekta nad kojim se generiše SAS, različite dozvole mogu biti uključene. Na primer: - (a)dd, (c)reate, (d)elete, (e)xecute, (f)ilter_by_tags, (i)set_immutability_policy, (l)ist, (m)ove, (r)ead, (t)ag, (w)rite, (x)delete_previous_version, (y)permanent_delete -## SFTP Support for Azure Blob Storage +## SFTP Podrška za Azure Blob Storage -Azure Blob Storage now supports the SSH File Transfer Protocol (SFTP), enabling secure file transfer and management directly to Blob Storage without requiring custom solutions or third-party products. +Azure Blob Storage sada podržava SSH File Transfer Protocol (SFTP), omogućavajući sigurnu razmenu i upravljanje datotekama direktno u Blob Storage bez potrebe za prilagođenim rešenjima ili proizvodima trećih strana. -### Key Features +### Ključne Karakteristike -- Protocol Support: SFTP works with Blob Storage accounts configured with hierarchical namespace (HNS). This organizes blobs into directories and subdirectories for easier navigation. -- Security: SFTP uses local user identities for authentication and does not integrate with RBAC or ABAC. Each local user can authenticate via: - - Azure-generated passwords - - Public-private SSH key pairs -- Granular Permissions: Permissions such as Read, Write, Delete, and List can be assigned to local users for up to 100 containers. -- Networking Considerations: SFTP connections are made through port 22. Azure supports network configurations like firewalls, private endpoints, or virtual networks to secure SFTP traffic. +- Podrška za protokol: SFTP radi sa Blob Storage nalozima konfiguriranim sa hijerarhijskim imenskim prostorom (HNS). Ovo organizuje blobove u direktorijume i poddirektorijume radi lakše navigacije. +- Bezbednost: SFTP koristi lokalne korisničke identitete za autentifikaciju i ne integriše se sa RBAC ili ABAC. Svaki lokalni korisnik može se autentifikovati putem: +- Azure generisanih lozinki +- Javnih i privatnih SSH ključeva +- Granularne dozvole: Dozvole kao što su Čitanje, Pisanje, Brisanje i Lista mogu se dodeliti lokalnim korisnicima za do 100 kontejnera. +- Mrežne razmatranja: SFTP veze se uspostavljaju preko porta 22. Azure podržava mrežne konfiguracije kao što su vatrozidi, privatne tačke ili virtuelne mreže za zaštitu SFTP saobraćaja. -### Setup Requirements +### Zahtevi za postavljanje -- Hierarchical Namespace: HNS must be enabled when creating the storage account. -- Supported Encryption: Requires Microsoft Security Development Lifecycle (SDL)-approved cryptographic algorithms (e.g., rsa-sha2-256, ecdsa-sha2-nistp256). -- SFTP Configuration: - - Enable SFTP on the storage account. - - Create local user identities with appropriate permissions. - - Configure home directories for users to define their starting location within the container. +- Hijerarhijski imenski prostor: HNS mora biti omogućen prilikom kreiranja naloga za skladištenje. +- Podržana enkripcija: Zahteva Microsoft Security Development Lifecycle (SDL) odobrene kriptografske algoritme (npr., rsa-sha2-256, ecdsa-sha2-nistp256). +- SFTP konfiguracija: +- Omogućite SFTP na nalogu za skladištenje. +- Kreirajte lokalne korisničke identitete sa odgovarajućim dozvolama. +- Konfigurišite početne direktorijume za korisnike kako biste definisali njihovu početnu lokaciju unutar kontejnera. -### Permissions +### Dozvole -| Permission | Symbol | Description | -| ---------------------- | ------ | ------------------------------------ | -| **Read** | `r` | Read file content. | -| **Write** | `w` | Upload files and create directories. | -| **List** | `l` | List contents of directories. | -| **Delete** | `d` | Delete files or directories. | -| **Create** | `c` | Create files or directories. | -| **Modify Ownership** | `o` | Change the owning user or group. | -| **Modify Permissions** | `p` | Change ACLs on files or directories. | +| Dozvola | Simbol | Opis | +| --------------------- | ------ | --------------------------------------- | +| **Čitanje** | `r` | Čitaj sadržaj datoteke. | +| **Pisanje** | `w` | Učitaj datoteke i kreiraj direktorijume. | +| **Lista** | `l` | Lista sadržaj direktorijuma. | +| **Brisanje** | `d` | Obriši datoteke ili direktorijume. | +| **Kreiranje** | `c` | Kreiraj datoteke ili direktorijume. | +| **Izmena vlasništva** | `o` | Promeni vlasničkog korisnika ili grupu. | +| **Izmena dozvola** | `p` | Promeni ACL-ove na datotekama ili direktorijumima. | -## Enumeration +## Enumeracija {{#tabs }} {{#tab name="az cli" }} -

It offers high availability, low latency, and scalability to handle large datasets efficiently. Data is organized into tables, with each entity identified by a partition key and row key, enabling fast lookups. It supports features like encryption at rest, role-based access control, and shared access signatures for secure, managed storage suitable for a wide range of applications. +**Azure Table Storage** je NoSQL skladište ključ-vrednost dizajnirano za skladištenje velikih količina strukturiranih, nestrukturiranih podataka. Pruža visoku dostupnost, nisku latenciju i skalabilnost za efikasno upravljanje velikim skupovima podataka. Podaci su organizovani u tabele, pri čemu je svaka entitet identifikovan pomoću partition key i row key, što omogućava brze pretrage. Podržava funkcije kao što su enkripcija u mirovanju, kontrola pristupa zasnovana na ulogama i potpisane pristupne dozvole za sigurno, upravljano skladištenje pogodno za širok spektar aplikacija. -There **isn't built-in backup mechanism** for table storage. +**Ne postoji ugrađeni mehanizam za backup** za table storage. -### Keys +### Ključevi #### **PartitionKey** -- The **PartitionKey groups entities into logical partitions**. Entities with the same PartitionKey are stored together, which improves query performance and scalability. -- Example: In a table storing employee data, `PartitionKey` might represent a department, e.g., `"HR"` or `"IT"`. +- **PartitionKey grupiše entitete u logičke particije**. Entiteti sa istim PartitionKey se skladište zajedno, što poboljšava performanse upita i skalabilnost. +- Primer: U tabeli koja skladišti podatke o zaposlenima, `PartitionKey` može predstavljati odeljenje, npr., `"HR"` ili `"IT"`. #### **RowKey** -- The **RowKey is the unique identifier** for an entity within a partition. When combined with the PartitionKey, it ensures that each entity in the table has a globally unique identifier. -- Example: For the `"HR"` partition, `RowKey` might be an employee ID, e.g., `"12345"`. +- **RowKey je jedinstveni identifikator** za entitet unutar particije.

Site Recovery **replicates workloads** running on physical and virtual machines (VMs) from a primary site to a secondary location. When an outage occurs at your primary site, you fail over to a secondary location, and access apps from there. After the primary location is running again, you can fail back to it. +Iz [**dokumentacije**](https://learn.microsoft.com/en-us/azure/site-recovery/site-recovery-overview): Site Recovery pomaže u obezbeđivanju kontinuiteta poslovanja tako što održava poslovne aplikacije i radne opterećenja u radu tokom prekida. Site Recovery **replicira radna opterećenja** koja se izvode na fizičkim i virtuelnim mašinama (VM) sa primarne lokacije na sekundarnu lokaciju. Kada dođe do prekida na vašoj primarnoj lokaciji, prebacujete se na sekundarnu lokaciju i pristupate aplikacijama odatle. Kada primarna lokacija ponovo počne da radi, možete se vratiti na nju. ## Azure Bastion -Azure Bastion enables secure and seamless **Remote Desktop Protocol (RDP)** and **Secure Shell (SSH)** access to your virtual machines (VMs) directly through the Azure Portal or via a jump box. By **eliminating the need for public IP addresses** on your VMs. +Azure Bastion omogućava siguran i neometan **Remote Desktop Protocol (RDP)** i **Secure Shell (SSH)** pristup vašim virtuelnim mašinama (VM) direktno kroz Azure Portal ili putem jump box-a. Tako što **uklanja potrebu za javnim IP adresama** na vašim VM-ima. -The Bastion deploys a subnet called **`AzureBastionSubnet`** with a `/26` netmask in the VNet it needs to work on. Then, it allows to **connect to internal VMs through the browser** using `RDP` and `SSH` avoiding exposing ports of the VMs to the Internet. It can also work as a **jump host**. +Bastion postavlja podmrežu nazvanu **`AzureBastionSubnet`** sa `/26` maskom u VNet-u na kojem treba da radi. Zatim omogućava **povezivanje sa internim VM-ima putem pregledača** koristeći `RDP` i `SSH`, izbegavajući izlaganje portova VM-ova internetu. Takođe može raditi kao **jump host**. -To list all Azure Bastion Hosts in your subscription and connect to VMs through them, you can use the following commands: +Da biste naveli sve Azure Bastion hostove u vašoj pretplati i povezali se sa VM-ima preko njih, možete koristiti sledeće komande: {{#tabs}} {{#tab name="az cli"}} - ```bash # List bastions az network bastion list -o table # Connect via SSH through bastion az network bastion ssh \ - --name MyBastion \ - --resource-group MyResourceGroup \ - --target-resource-id /subscriptions/12345678-1234-1234-1234-123456789abc/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM \ - --auth-type ssh-key \ - --username azureuser \ - --ssh-key ~/.ssh/id_rsa +--name MyBastion \ +--resource-group MyResourceGroup \ +--target-resource-id /subscriptions/12345678-1234-1234-1234-123456789abc/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM \ +--auth-type ssh-key \ +--username azureuser \ +--ssh-key ~/.ssh/id_rsa # Connect via RDP through bastion az network bastion rdp \ - --name \ - --resource-group \ - --target-resource-id /subscriptions//resourceGroups//providers/Microsoft.Compute/virtualMachines/ \ - --auth-type password \ - --username \ - --password +--name \ +--resource-group \ +--target-resource-id /subscriptions//resourceGroups//providers/Microsoft.Compute/virtualMachines/ \ +--auth-type password \ +--username \ +--password ``` - {{#endtab}} {{#tab name="PowerShell"}} - ```powershell # List bastions Get-AzBastion ``` - {{#endtab}} {{#endtabs}} ## Metadata -The Azure Instance Metadata Service (IMDS) **provides information about running virtual machine instances** to assist with their management and configuration.

Communication between the VM and IMDS stays within the host, ensuring secure access. When querying IMDS, HTTP clients inside the VM should bypass web proxies to ensure proper communication. +Azure Instance Metadata Service (IMDS) **pruža informacije o aktivnim instancama virtuelnih mašina** kako bi pomogao u njihovom upravljanju i konfiguraciji.

Evo kako bi to moglo da se odvija: -The attack involves several steps targeting a generic company. Here's how it might unfold: +1. **Registracija Domen i Hosting Aplikacije**: Napadač registruje domen koji podseća na pouzdanu stranicu, na primer, "safedomainlogin.com". Pod ovim domenom, kreira se poddomen (npr. "companyname.safedomainlogin.com") za hosting aplikacije dizajnirane da prikupi autorizacione kodove i zatraži pristupne tokene. +2. **Registracija Aplikacije u Azure AD**: Napadač zatim registruje Multi-Tenant Aplikaciju u svom Azure AD Tenant-u, nazivajući je po ciljanom preduzeću kako bi izgledala legitimno. Konfiguriše URL za preusmeravanje aplikacije da upućuje na poddomen koji hostuje zlonamernu aplikaciju. +3. **Postavljanje Dozvola**: Napadač postavlja aplikaciju sa raznim API dozvolama (npr. `Mail.Read`, `Notes.Read.All`, `Files.ReadWrite.All`, `User.ReadBasic.All`, `User.Read`). Ove dozvole, kada ih korisnik odobri, omogućavaju napadaču da izvuče osetljive informacije u ime korisnika. +4. **Distribucija Zlonamernih Linkova**: Napadač kreira link koji sadrži ID klijenta zlonamerne aplikacije i deli ga sa ciljnim korisnicima, obmanjujući ih da daju saglasnost. -1. **Domain Registration and Application Hosting**: The attacker registers a domain resembling a trustworthy site, for example, "safedomainlogin.com". Under this domain, a subdomain is created (e.g., "companyname.safedomainlogin.com") to host an application designed to capture authorization codes and request access tokens. -2. **Application Registration in Azure AD**: The attacker then registers a Multi-Tenant Application in their Azure AD Tenant, naming it after the target company to appear legitimate. They configure the application's Redirect URL to point to the subdomain hosting the malicious application. -3. **Setting Up Permissions**: The attacker sets up the application with various API permissions (e.g., `Mail.Read`, `Notes.Read.All`, `Files.ReadWrite.All`, `User.ReadBasic.All`, `User.Read`). These permissions, once granted by the user, allow the attacker to extract sensitive information on behalf of the user. -4. **Distributing Malicious Links**: The attacker crafts a link containing the client id of the malicious application and shares it with targeted users, tricking them into granting consent. +## Primer Napada -## Example Attack - -1. Register a **new application**. It can be only for the current directory if you are using an user from the attacked directory or for any directory if this is an external attack (like in the following image). - 1. Also set the **redirect URI** to the expected URL where you want to receive the code to the get tokens (`http://localhost:8000/callback` by default). +1. Registrujte **novu aplikaciju**. Može biti samo za trenutni direktorijum ako koristite korisnika iz napadnutog direktorijuma ili za bilo koji direktorijum ako je ovo spoljašnji napad (kao na sledećoj slici). +1. Takođe postavite **redirect URI** na očekivani URL gde želite da primite kod za dobijanje tokena (`http://localhost:8000/callback` po defaultu).

This includes encryption, backups, and other security measures. +- **Virtuelni privatni serveri (VPS)**: DigitalOcean pruža VPS koji se mogu koristiti za hostovanje veb sajtova i aplikacija.

Ovo uključuje enkripciju, rezervne kopije i druge mere bezbednosti. -Overall, DigitalOcean is a cloud computing platform that provides users with the tools and resources they need to build, deploy, and manage applications in the cloud. Its services are designed to be simple and easy to use, making them popular among developers and small businesses. +Sve u svemu, DigitalOcean je platforma za cloud računarstvo koja korisnicima pruža alate i resurse potrebne za izgradnju, implementaciju i upravljanje aplikacijama u cloudu. Njegove usluge su dizajnirane da budu jednostavne i lake za korišćenje, što ih čini popularnim među programerima i malim preduzećima. -### Main Differences from AWS +### Glavne razlike u odnosu na AWS -One of the main differences between DigitalOcean and AWS is the **range of services they offer**. **DigitalOcean focuses on providing simple** and easy-to-use virtual private servers (VPS), storage, and development and deployment tools. **AWS**, on the other hand, offers a **much broader range of services**, including VPS, storage, databases, machine learning, analytics, and many other services. This means that AWS is more suitable for complex, enterprise-level applications, while DigitalOcean is more suited to small businesses and developers. +Jedna od glavnih razlika između DigitalOcean-a i AWS-a je **raspon usluga koje nude**. **DigitalOcean se fokusira na pružanje jednostavnih** i lakih za korišćenje virtuelnih privatnih servera (VPS), skladištenja i alata za razvoj i implementaciju. **AWS**, s druge strane, nudi **mnogo širi spektar usluga**, uključujući VPS, skladištenje, baze podataka, mašinsko učenje, analitiku i mnoge druge usluge. To znači da je AWS pogodniji za složene, aplikacije na nivou preduzeća, dok je DigitalOcean više prilagođen malim preduzećima i programerima. -Another key difference between the two platforms is the **pricing structure**. **DigitalOcean's pricing is generally more straightforward and easier** to understand than AWS, with a range of pricing plans that are based on the number of droplets and other resources used. AWS, on the other hand, has a more complex pricing structure that is based on a variety of factors, including the type and amount of resources used. This can make it more difficult to predict costs when using AWS. +Još jedna ključna razlika između dve platforme je **struktura cena**. **Cene DigitalOcean-a su generalno jednostavnije i lakše** za razumevanje od AWS-a, sa nizom planova cena koji se zasnivaju na broju dropleta i drugih korišćenih resursa. AWS, s druge strane, ima složeniju strukturu cena koja se zasniva na raznim faktorima, uključujući tip i količinu korišćenih resursa. Ovo može otežati predviđanje troškova prilikom korišćenja AWS-a. -## Hierarchy +## Hijerarhija -### User +### Korisnik -A user is what you expect, a user.

Snapshots are stored on DigitalOcean's object storage service, and they are incremental, meaning that only the changes since the last snapshot are stored. This makes them efficient to use and cost-effective to store. +Snimci se mogu koristiti za kreiranje novih Dropleta sa istom konfiguracijom kao originalni Droplet, ili za vraćanje Dropleta u stanje u kojem je bio kada je snimak napravljen. Snimci se čuvaju na DigitalOcean-ovoj usluzi za skladištenje objekata, i oni su inkrementalni, što znači da se čuvaju samo promene od poslednjeg snimka. Ovo ih čini efikasnim za korišćenje i isplativim za skladištenje. -On the other hand, a backup is a complete copy of a Droplet, including the operating system, installed applications, files, and data, as well as the Droplet's settings and metadata. Backups are typically performed on a regular schedule, and they capture the entire state of a Droplet at a specific point in time. +S druge strane, rezervna kopija je potpuna kopija Dropleta, uključujući operativni sistem, instalirane aplikacije, datoteke i podatke, kao i postavke i metapodatke Dropleta. Rezervne kopije se obično vrše prema redovnom rasporedu, i one hvataju celo stanje Dropleta u određenom trenutku. -Unlike snapshots, backups are stored in a compressed and encrypted format, and they are transferred off of DigitalOcean's infrastructure to a remote location for safekeeping. This makes backups ideal for disaster recovery, as they provide a complete copy of a Droplet that can be restored in the event of data loss or other catastrophic events. +Za razliku od snimaka, rezervne kopije se čuvaju u komprimovanom i enkriptovanom formatu, i one se prenose sa DigitalOcean-ove infrastrukture na udaljenu lokaciju radi čuvanja.

Snapshots are stored on DigitalOcean's object storage service, while backups are transferred off of DigitalOcean's infrastructure to a remote location. Both snapshots and backups can be used to restore a Droplet, but snapshots are more efficient to use and store, while backups provide a more comprehensive backup solution for disaster recovery. +Ukratko, snimci su tačke u vremenu kopije diska Dropleta, dok su rezervne kopije potpune kopije Dropleta, uključujući njegove postavke i metapodatke. Snimci se čuvaju na DigitalOcean-ovoj usluzi za skladištenje objekata, dok se rezervne kopije prenose sa DigitalOcean-ove infrastrukture na udaljenu lokaciju. I snimci i rezervne kopije se mogu koristiti za vraćanje Dropleta, ali su snimci efikasniji za korišćenje i skladištenje, dok rezervne kopije pružaju sveobuhvatnije rešenje za oporavak od katastrofa.

-## **Projects Migration** +## **Migracija Projekata** -It's possible to **migrate a project without any organization** to an organization with the permissions `roles/resourcemanager.projectCreator` and `roles/resourcemanager.projectMover`. If the project is inside other organization, it's needed to contact GCP support to **move them out of the organization first**. For more info check [**this**](https://medium.com/google-cloud/migrating-a-project-from-one-organization-to-another-gcp-4b37a86dd9e6). +Moguće je **migrirati projekat bez organizacije** u organizaciju sa dozvolama `roles/resourcemanager.projectCreator` i `roles/resourcemanager.projectMover`. Ako je projekat unutar druge organizacije, potrebno je kontaktirati GCP podršku da **ih prvo premeste iz organizacije**.

-These are the policies that Google will add by default when setting up your GCP organization: +Ovo su politike koje će Google dodati podrazumevano prilikom postavljanja vaše GCP organizacije: -**Access Management Policies** +**Politike upravljanja pristupom** -- **Domain restricted contacts:** Prevents adding users to Essential Contacts outside your specified domains. This limits Essential Contacts to only allow managed user identities in your selected domains to receive platform notifications. -- **Domain restricted sharing:** Prevents adding users to IAM policies outside your specified domains. This limits IAM policies to only allow managed user identities in your selected domains to access resources inside this organization. -- **Public access prevention:** Prevents Cloud Storage buckets from being exposed to the public. This ensures that a developer can't configure Cloud Storage buckets to have unauthenticated internet access. -- **Uniform bucket level access:** Prevents object-level access control lists (ACLs) in Cloud Storage buckets. This simplifies your access management by applying IAM policies consistently across all objects in Cloud Storage buckets. -- **Require OS login:** VMs created in new projects will have OS Login enabled. This lets you manage SSH access to your instances using IAM without needing to create and manage individual SSH keys. +- **Kontakti sa ograničenim domenom:** Sprečava dodavanje korisnika u Esencijalne kontakte van vaših specificiranih domena. Ovo ograničava Esencijalne kontakte da dozvole samo upravljanim identitetima korisnika u vašim odabranim domenama da primaju obaveštenja sa platforme. +- **Deljenje sa ograničenim domenom:** Sprečava dodavanje korisnika u IAM politike van vaših specificiranih domena. Ovo ograničava IAM politike da dozvole samo upravljanim identitetima korisnika u vašim odabranim domenama da pristupaju resursima unutar ove organizacije. +- **Sprečavanje javnog pristupa:** Sprečava Cloud Storage kante da budu izložene javnosti. Ovo osigurava da programer ne može konfigurisati Cloud Storage kante da imaju neautentifikovani pristup internetu. +- **Uniformni pristup na nivou kante:** Sprečava liste kontrola pristupa (ACL) na nivou objekta u Cloud Storage kantama. Ovo pojednostavljuje vaše upravljanje pristupom primenom IAM politika dosledno na svim objektima u Cloud Storage kantama. +- **Zahtevajte OS prijavu:** VMs kreirane u novim projektima će imati omogućenu OS prijavu. Ovo vam omogućava da upravljate SSH pristupom vašim instancama koristeći IAM bez potrebe da kreirate i upravljate pojedinačnim SSH ključevima. -**Additional security policies for service accounts** +**Dodatne sigurnosne politike za naloge usluga** -- **Disable automatic IAM grants**: Prevents the default App Engine and Compute Engine service accounts from automatically being granted the Editor IAM role on a project at creation. This ensures service accounts don't receive overly-permissive IAM roles upon creation. -- **Disable service account key creation**: Prevents the creation of public service account keys. This helps reduce the risk of exposing persistent credentials. -- **Disable service account key upload**: Prevents the uploading of public service account keys. This helps reduce the risk of leaked or reused key material. +- **Onemogućite automatske IAM dozvole**: Sprečava da se podrazumevani App Engine i Compute Engine nalozi usluga automatski dodeljuju IAM ulogu urednika prilikom kreiranja projekta. Ovo osigurava da nalozi usluga ne dobiju previše dozvola prilikom kreiranja. +- **Onemogućite kreiranje ključeva naloga usluga**: Sprečava kreiranje javnih ključeva naloga usluga. Ovo pomaže u smanjenju rizika od izlaganja trajnih akreditiva. +- **Onemogućite otpremu ključeva naloga usluga**: Sprečava otpremu javnih ključeva naloga usluga. Ovo pomaže u smanjenju rizika od curenja ili ponovne upotrebe materijala ključeva. -**Secure VPC network configuration policies** +**Politike konfiguracije sigurnih VPC mreža** -- **Define allowed external IPs for VM instances**: Prevents the creation of Compute instances with a public IP, which can expose them to internet traffic. +- **Definišite dozvoljene spoljne IP adrese za VM instance**: Sprečava kreiranje Compute instanci sa javnim IP, što može izložiti internet saobraćaju. -* **Disable VM nested virtualization**: Prevents the creation of nested VMs on Compute Engine VMs. This decreases the security risk of having unmonitored nested VMs. +* **Onemogućite VM ugnježdenu virtualizaciju**: Sprečava kreiranje ugnježdenih VMs na Compute Engine VMs. Ovo smanjuje sigurnosni rizik od neproverenih ugnježdenih VMs. -- **Disable VM serial port:** Prevents serial port access to Compute Engine VMs. This prevents input to a server’s serial port using the Compute Engine API. +- **Onemogućite serijski port VM:** Sprečava pristup serijskom portu Compute Engine VMs. Ovo sprečava unos u serijski port servera koristeći Compute Engine API. -* **Restrict authorized networks on Cloud SQL instances:** Prevents public or non-internal network ranges from accessing your Cloud SQL databases. +* **Ograničite autorizovane mreže na Cloud SQL instancama:** Sprečava javne ili neinternetske mrežne opsege da pristupaju vašim Cloud SQL bazama podataka. -- **Restrict Protocol Forwarding Based on type of IP Address:** Prevents VM protocol forwarding for external IP addresses. +- **Ograničite prosleđivanje protokola na osnovu tipa IP adrese:** Sprečava prosleđivanje protokola VM za spoljne IP adrese. -* **Restrict Public IP access on Cloud SQL instances:** Prevents the creation of Cloud SQL instances with a public IP, which can expose them to internet traffic. +* **Ograničite javni pristup IP na Cloud SQL instancama:** Sprečava kreiranje Cloud SQL instanci sa javnim IP, što može izložiti internet saobraćaju. -- **Restrict shared VPC project lien removal:** Prevents the accidental deletion of Shared VPC host projects. +- **Ograničite uklanjanje tereta zajedničkog VPC projekta:** Sprečava slučajno brisanje zajedničkih VPC host projekata. -* **Sets the internal DNS setting for new projects to Zonal DNS Only:** Prevents the use of a legacy DNS setting that has reduced service availability. +* **Postavlja unutrašnju DNS postavku za nove projekte na Zonal DNS Samo:** Sprečava korišćenje nasleđene DNS postavke koja je smanjila dostupnost usluga. -- **Skip default network creation:** Prevents automatic creation of the default VPC network and related resources. This avoids overly-permissive default firewall rules. +- **Preskočite kreiranje podrazumevane mreže:** Sprečava automatsko kreiranje podrazumevane VPC mreže i povezanih resursa. Ovo izbegava previše dozvola podrazumevanih pravila vatrozida. -* **Disable VPC External IPv6 usage:** Prevents the creation of external IPv6 subnets, which can be exposed to unauthorized internet access. +* **Onemogućite korišćenje VPC spoljnog IPv6:** Sprečava kreiranje spoljašnjih IPv6 podmreža, koje mogu biti izložene neovlašćenom pristupu internetu.
-## **IAM Roles** +## **IAM Uloge** -These are like IAM policies in AWS as **each role contains a set of permissions.** +Ove su slične IAM politikama u AWS-u jer **svaka uloga sadrži skup dozvola.** -However, unlike in AWS, there is **no centralized repo** of roles. Instead of that, **resources give X access roles to Y principals**, and the only way to find out who has access to a resource is to use the **`get-iam-policy` method over that resource**.\ -This could be a problem because this means that the only way to find out **which permissions a principal has is to ask every resource who is it giving permissions to**, and a user might not have permissions to get permissions from all resources. +Međutim, za razliku od AWS-a, ne postoji **centralizovani repozitorij** uloga. Umesto toga, **resursi daju X pristupne uloge Y principima**, a jedini način da saznate ko ima pristup resursu je korišćenje **`get-iam-policy` metode nad tim resursom**.\ +To može biti problem jer to znači da je jedini način da saznate **koje dozvole ima princip da pitate svaki resurs kome dodeljuje dozvole**, a korisnik možda nema dozvole da dobije dozvole od svih resursa. -There are **three types** of roles in IAM: +Postoje **tri tipa** uloga u IAM: -- **Basic/Primitive roles**, which include the **Owner**, **Editor**, and **Viewer** roles that existed prior to the introduction of IAM. -- **Predefined roles**, which provide granular access for a specific service and are managed by Google Cloud.

-## **Service accounts** +## **Nalozi usluga** -These are the principals that **resources** can **have** **attached** and access to interact easily with GCP. For example, it's possible to access the **auth token** of a Service Account **attached to a VM** in the metadata.\ -It is possible to encounter some **conflicts** when using both **IAM and access scopes**. For example, your service account may have the IAM role of `compute.instanceAdmin` but the instance you've breached has been crippled with the scope limitation of `https://www.googleapis.com/auth/compute.readonly`. This would prevent you from making any changes using the OAuth token that's automatically assigned to your instance. +Ovo su principi koje **resursi** mogu **imati** **priključene** i pristupiti kako bi lako interagovali sa GCP-om. Na primer, moguće je pristupiti **auth tokenu** naloga usluga **priključenog VM-u** u metapodacima.\ +Moguće je naići na neke **sukobe** kada se koriste i **IAM i pristupne oblasti**. Na primer, vaš nalog usluga može imati IAM ulogu `compute.instanceAdmin`, ali instanca koju ste kompromitovali ima ograničenje opsega `https://www.googleapis.com/auth/compute.readonly`. Ovo bi vam onemogućilo da napravite bilo kakve promene koristeći OAuth token koji je automatski dodeljen vašoj instanci. -It's similar to **IAM roles from AWS**. But not like in AWS, **any** service account can be **attached to any service** (it doesn't need to allow it via a policy). - -Several of the service accounts that you will find are actually **automatically generated by GCP** when you start using a service, like: +Slično je **IAM ulogama iz AWS-a**. Ali ne kao u AWS-u, **bilo koji** nalog usluga može biti **priključen bilo kojoj usluzi** (ne mora to dozvoliti putem politike). +Nekoliko naloga usluga koje ćete pronaći su zapravo **automatski generisani od strane GCP-a** kada počnete koristiti uslugu, kao: ``` PROJECT_NUMBER-compute@developer.gserviceaccount.com PROJECT_ID@appspot.gserviceaccount.com ``` - -However, it's also possible to create and attach to resources **custom service accounts**, which will look like this: - +Međutim, takođe je moguće kreirati i povezati se sa resursima **prilagođenim servisnim nalozima**, koji će izgledati ovako: ``` SERVICE_ACCOUNT_NAME@PROJECT_NAME.iam.gserviceaccount.com ``` +### **Ključevi i Tokeni** -### **Keys & Tokens** +Postoje 2 glavna načina za pristup GCP kao servisni nalog: -There are 2 main ways to access GCP as a service account: +- **Putem OAuth tokena**: Ovo su tokeni koje ćete dobiti sa mesta kao što su metapodaci ili krađom http zahteva i ograničeni su **opsegom pristupa**. +- **Ključevi**: Ovo su javni i privatni parovi ključeva koji će vam omogućiti da potpišete zahteve kao servisni nalog i čak generišete OAuth tokene za izvršavanje akcija kao servisni nalog. Ovi ključevi su opasni jer je komplikovanije ograničiti i kontrolisati ih, zato GCP preporučuje da ih ne generišete. +- Imajte na umu da svaki put kada se kreira SA, **GCP generiše ključ za servisni nalog** kojem korisnik ne može pristupiti (i neće biti naveden u web aplikaciji). Prema [**ovoj temi**](https://www.reddit.com/r/googlecloud/comments/f0ospy/service_account_keys_observations/) ovaj ključ je **interno korišćen od strane GCP** da omogući metapodacima pristup za generisanje dostupnih OAuth tokena. -- **Via OAuth tokens**: These are tokens that you will get from places like metadata endpoints or stealing http requests and they are limited by the **access scopes**. -- **Keys**: These are public and private key pairs that will allow you to sign requests as the service account and even generate OAuth tokens to perform actions as the service account. These keys are dangerous because they are more complicated to limit and control, that's why GCP recommend to not generate them. - - Note that every-time a SA is created, **GCP generates a key for the service account** that the user cannot access (and won't be listed in the web application). According to [**this thread**](https://www.reddit.com/r/googlecloud/comments/f0ospy/service_account_keys_observations/) this key is **used internally by GCP** to give metadata endpoints access to generate the accesible OAuth tokens. +### **Opsezi pristupa** -### **Access scopes** +Opsezi pristupa su **priključeni generisanim OAuth tokenima** za pristup GCP API krajnjim tačkama. Oni **ograničavaju dozvole** OAuth tokena.\ +To znači da ako token pripada vlasniku resursa, ali nema u opsegu tokena pristup tom resursu, token **ne može biti korišćen za (zlo)upotrebu tih privilegija**. -Access scope are **attached to generated OAuth tokens** to access the GCP API endpoints. They **restrict the permissions** of the OAuth token.\ -This means that if a token belongs to an Owner of a resource but doesn't have the in the token scope to access that resource, the token **cannot be used to (ab)use those privileges**. - -Google actually [recommends](https://cloud.google.com/compute/docs/access/service-accounts#service_account_permissions) that **access scopes are not used and to rely totally on IAM**. The web management portal actually enforces this, but access scopes can still be applied to instances using custom service accounts programmatically. - -You can see what **scopes** are **assigned** by **querying:** +Google zapravo [preporučuje](https://cloud.google.com/compute/docs/access/service-accounts#service_account_permissions) da **opsezi pristupa ne budu korišćeni i da se potpuno oslanjaju na IAM**.

Možete postaviti korisnika kao člana uloge, a zatim postaviti grupu kao člana iste uloge i takođe postaviti te principe (korisnika i grupu) kao članove drugih uloga. +- **Povezivanja**: Nekoliko **principala može biti povezano sa ulogom**. Ti **principali mogu i dalje biti povezani ili članovi drugih uloga**. Međutim, ako je principal koji nije povezan sa ulogom postavljen kao **član povezane uloge**, sledeći put kada se **povezivanje primeni, članstvo će nestati**. +- **Politike**: Politika je **autoritativna**, ukazuje na uloge i principe i tada, **ti principi ne mogu imati više uloga i te uloge ne mogu imati više principa** osim ako ta politika nije izmenjena (čak ni u drugim politikama, povezivanjima ili članstvima). Stoga, kada je uloga ili principal specificiran u politici, sva njegova ovlašćenja su **ograničena tom politikom**. Očigledno, ovo se može zaobići u slučaju da principal dobije opciju da izmeni politiku ili dozvole za eskalaciju privilegija (kao što je kreiranje novog principala i povezivanje njega sa novom ulogom). -- **Memberships**: You set **principals as members of roles** **without restrictions** over the role or the principals. You can put a user as a member of a role and then put a group as a member of the same role and also set those principals (user and group) as member of other roles. -- **Bindings**: Several **principals can be binded to a role**. Those **principals can still be binded or be members of other roles**. However, if a principal which isn’t binded to the role is set as **member of a binded role**, the next time the **binding is applied, the membership will disappear**. -- **Policies**: A policy is **authoritative**, it indicates roles and principals and then, **those principals cannot have more roles and those roles cannot have more principals** unless that policy is modified (not even in other policies, bindings or memberships). Therefore, when a role or principal is specified in policy all its privileges are **limited by that policy**. Obviously, this can be bypassed in case the principal is given the option to modify the policy or privilege escalation permissions (like create a new principal and bind him a new role). - -## References +## Reference -

This means that you will be able to launch a resource with a SA, get into the resource, and **steal the SA token**. Therefore, this will allow to escalate to a principal via a resource escalation. This has happened in several resources previously, but now it’s less frequent (but can still happen). +- **Privesc to a principal**: Ovo će vam omogućiti da **imituješ drugi princip**, i stoga delujete kao on sa svim njegovim dozvolama. npr.: Zloupotreba _getAccessToken_ za imitaciju servisnog naloga. +- **Privesc on the resource**: Ovo će vam omogućiti da **dobijete više dozvola nad specifičnim resursom**. npr.: možete zloupotrebiti _setIamPolicy_ dozvolu nad cloudfunctions da biste omogućili pokretanje funkcije. +- Imajte na umu da neke **dozvole resursa će takođe omogućiti da prikačite proizvoljni servisni nalog** na resurs.

Ovo se ranije dešavalo na nekoliko resursa, ali sada je ređe (ali se i dalje može desiti). -Obviously, the most interesting privilege escalation techniques are the ones of the **second group** because it will allow you to **get more privileges outside of the resources you already have** some privileges over. However, note that **escalating in resources** may give you also access to **sensitive information** or even to **other principals** (maybe via reading a secret that contains a token of a SA). +Očigledno, najzanimljivije tehnike eskalacije privilegija su one iz **druge grupe** jer će vam omogućiti da **dobijete više privilegija van resursa nad kojima već imate** neke privilegije.

For example, if the token has the **`https://www.googleapis.com/auth/cloud-platform`** scope, it will have **full access** to all GCP services. However, if the token has the **`https://www.googleapis.com/auth/cloud-platform.read-only`** scope, it will only have **read-only access** to all GCP services even if the SA has more permissions in IAM. +Tokeni SA koji su procurili iz GCP metadata servisa imaju **access scopes**. Ovo su **ograničenja** na **dozvole** koje token ima. Na primer, ako token ima **`https://www.googleapis.com/auth/cloud-platform`** opseg, imaće **potpun pristup** svim GCP uslugama. Međutim, ako token ima **`https://www.googleapis.com/auth/cloud-platform.read-only`** opseg, imaće samo **pristup za čitanje** svim GCP uslugama čak i ako SA ima više dozvola u IAM-u. -There is no direct way to bypass these permissions, but you could always try searching for **new credentials** in the compromised host, **find the service key** to generate an OAuth token without restriction or **jump to a different VM less restricted**. +Ne postoji direktan način da se zaobiđu ove dozvole, ali uvek možete pokušati da tražite **nove kredencijale** na kompromitovanom hostu, **pronađete servisni ključ** za generisanje OAuth tokena bez ograničenja ili **preskočite na drugu VM sa manje ograničenja**. -When [access scopes](https://cloud.google.com/compute/docs/access/service-accounts#accesscopesiam) are used, the OAuth token that is generated for the computing instance (VM) will **have a** [**scope**](https://oauth.net/2/scope/) **limitation included**.

Instances that do not block project-wide keys will accept the SSH key, granting access. - - A direct method to SSH into an instance is using the `gcloud compute ssh [INSTANCE]` command. This command uses your current username and the SSH keys set at the project level to attempt access. - -## References +## Reference - [https://about.gitlab.com/blog/2020/02/12/plundering-gcp-escalating-privileges-in-google-cloud-platform/](https://about.gitlab.com/blog/2020/02/12/plundering-gcp-escalating-privileges-in-google-cloud-platform/) {{#include ../../../../banners/hacktricks-training.md}} - - - - diff --git a/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-container-privesc.md b/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-container-privesc.md index ea10ba464..8ed9e98ed 100644 --- a/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-container-privesc.md +++ b/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-container-privesc.md @@ -6,90 +6,82 @@ ### `container.clusters.get` -This permission allows to **gather credentials for the Kubernetes cluster** using something like: - +Ova dozvola omogućava **prikupljanje kredencijala za Kubernetes klaster** koristeći nešto poput: ```bash gcloud container clusters get-credentials --zone ``` - -Without extra permissions, the credentials are pretty basic as you can **just list some resource**, but hey are useful to find miss-configurations in the environment. +Bez dodatnih dozvola, akreditivi su prilično osnovni jer možete **samo da nabrojite neke resurse**, ali su korisni za pronalaženje pogrešnih konfiguracija u okruženju. > [!NOTE] -> Note that **kubernetes clusters might be configured to be private**, that will disallow that access to the Kube-API server from the Internet. - -If you don't have this permission you can still access the cluster, but you need to **create your own kubectl config file** with the clusters info.

The difference with the previous method is that **instead of making google sign a blob containing a JWT, we use the signJWT method that already expects a JWT**. This makes it easier to use but you can only sign JWT instead of any bytes. +Napadač sa pomenutim dozvolama će moći da **potpiše dobro oblikovane JSON web tokene (JWT-ove)**. Razlika u odnosu na prethodnu metodu je u tome što **umesto da nateramo Google da potpiše blob koji sadrži JWT, koristimo metodu signJWT koja već očekuje JWT**. Ovo olakšava korišćenje, ali možete potpisati samo JWT umesto bilo kojih bajtova. -You can find a script to automate the [**creation, exploit and cleaning of a vuln environment here**](https://github.com/carlospolop/gcp_privesc_scripts/blob/main/tests/7-iam.serviceAccounts.signJWT.sh) and a python script to abuse this privilege [**here**](https://github.com/RhinoSecurityLabs/GCP-IAM-Privilege-Escalation/blob/master/ExploitScripts/iam.serviceAccounts.signJWT.py).

You can abuse it to **grant yourself** the permissions you need to impersonate the service account. In the following example we are granting ourselves the `roles/iam.serviceAccountTokenCreator` role over the interesting SA: - +Napadač sa pomenutim dozvolama će moći da **doda IAM politike servisnim nalozima**. Možete to zloupotrebiti da **dodelite sebi** dozvole koje su vam potrebne da biste se pretvarali da ste servisni nalog. U sledećem primeru dodeljujemo sebi ulogu `roles/iam.serviceAccountTokenCreator` nad interesantnim SA: ```bash gcloud iam service-accounts add-iam-policy-binding "${VICTIM_SA}@${PROJECT_ID}.iam.gserviceaccount.com" \ - --member="user:username@domain.com" \ - --role="roles/iam.serviceAccountTokenCreator" +--member="user:username@domain.com" \ +--role="roles/iam.serviceAccountTokenCreator" # If you still have prblem grant yourself also this permission gcloud iam service-accounts add-iam-policy-binding "${VICTIM_SA}@${PROJECT_ID}.iam.gserviceaccount.com" \ \ - --member="user:username@domain.com" \ - --role="roles/iam.serviceAccountUser" +--member="user:username@domain.com" \ +--role="roles/iam.serviceAccountUser" ``` - -You can find a script to automate the [**creation, exploit and cleaning of a vuln environment here**](https://github.com/carlospolop/gcp_privesc_scripts/blob/main/tests/d-iam.serviceAccounts.setIamPolicy.sh)**.** +Možete pronaći skriptu za automatizaciju [**kreiranja, eksploatacije i čišćenja ranjivog okruženja ovde**](https://github.com/carlospolop/gcp_privesc_scripts/blob/main/tests/d-iam.serviceAccounts.setIamPolicy.sh)**.** ### `iam.serviceAccounts.actAs` -The **iam.serviceAccounts.actAs permission** is like the **iam:PassRole permission from AWS**. It's essential for executing tasks, like initiating a Compute Engine instance, as it grants the ability to "actAs" a Service Account, ensuring secure permission management. Without this, users might gain undue access. Additionally, exploiting the **iam.serviceAccounts.actAs** involves various methods, each requiring a set of permissions, contrasting with other methods that need just one. +**iam.serviceAccounts.actAs dozvola** je poput **iam:PassRole dozvole iz AWS-a**. Ključna je za izvršavanje zadataka, kao što je pokretanje Compute Engine instance, jer omogućava sposobnost "delovanja kao" servisni nalog, osiguravajući bezbedno upravljanje dozvolama. Bez ovoga, korisnici bi mogli dobiti neprimeren pristup. Pored toga, eksploatacija **iam.serviceAccounts.actAs** uključuje različite metode, od kojih svaka zahteva skup dozvola, za razliku od drugih metoda koje zahtevaju samo jednu. -#### Service account impersonation +#### Impersonacija servisnog naloga -Impersonating a service account can be very useful to **obtain new and better privileges**. There are three ways in which you can [impersonate another service account](https://cloud.google.com/iam/docs/understanding-service-accounts#impersonating_a_service_account): +Impersonacija servisnog naloga može biti veoma korisna za **dobijanje novih i boljih privilegija**. Postoje tri načina na koja možete [impersonirati drugi servisni nalog](https://cloud.google.com/iam/docs/understanding-service-accounts#impersonating_a_service_account): -- Authentication **using RSA private keys** (covered above) -- Authorization **using Cloud IAM policies** (covered here) -- **Deploying jobs on GCP services** (more applicable to the compromise of a user account) +- Autentifikacija **koristeći RSA privatne ključeve** (pokazano iznad) +- Autorizacija **koristeći Cloud IAM politike** (pokazano ovde) +- **Implementacija poslova na GCP uslugama** (više primenljivo na kompromitaciju korisničkog naloga) ### `iam.serviceAccounts.getOpenIdToken` -An attacker with the mentioned permissions will be able to generate an OpenID JWT. These are used to assert identity and do not necessarily carry any implicit authorization against a resource. +Napadač sa pomenutim dozvolama će moći da generiše OpenID JWT. Ovi se koriste za potvrdu identiteta i ne nose nužno nikakvu implicitnu autorizaciju prema resursu. -According to this [**interesting post**](https://medium.com/google-cloud/authenticating-using-google-openid-connect-tokens-e7675051213b), it's necessary to indicate the audience (service where you want to use the token to authenticate to) and you will receive a JWT signed by google indicating the service account and the audience of the JWT. -

### `cloudkms.cryptoKeyVersions.useToDecryptViaDelegation` -Here's a conceptual breakdown of how this delegation works: +Evo konceptualnog pregleda kako ova delegacija funkcioniše: -1. **Service Account A** has direct access to decrypt using a specific key in KMS. -2. **Service Account B** is granted the `useToDecryptViaDelegation` permission. This allows it to request KMS to decrypt data on behalf of Service Account A. +1. **Servisni nalog A** ima direktan pristup za dekripciju koristeći određeni ključ u KMS-u. +2. **Servisni nalog B** dobija dozvolu `useToDecryptViaDelegation`. Ovo mu omogućava da zatraži KMS da dekriptuje podatke u ime Servisnog naloga A. -The usage of this **permission is implicit in the way that the KMS service checks permissions** when a decryption request is made. +Korišćenje ove **dozvole je implicitno u načinu na koji KMS servis proverava dozvole** kada se podnese zahtev za dekripciju. -When you make a standard decryption request using the Google Cloud KMS API (in Python or another language), the service **checks whether the requesting service account has the necessary permissions**. If the request is made by a service account with the **`useToDecryptViaDelegation`** permission, KMS verifies whether this **account is allowed to request decryption on behalf of the entity that owns the key**. +Kada podnesete standardni zahtev za dekripciju koristeći Google Cloud KMS API (u Pythonu ili drugom jeziku), servis **proverava da li servisni nalog koji podnosi zahtev ima potrebne dozvole**. Ako zahtev podnosi servisni nalog sa **`useToDecryptViaDelegation`** dozvolom, KMS proverava da li je **ovaj nalog ovlašćen da zatraži dekripciju u ime entiteta koji poseduje ključ**. -#### Setting Up for Delegation - -1. **Define the Custom Role**: Create a YAML file (e.g., `custom_role.yaml`) that defines the custom role. This file should include the `cloudkms.cryptoKeyVersions.useToDecryptViaDelegation` permission. Here's an example of what this file might look like: +#### Podešavanje za Delegaciju +1. **Definišite Prilagođenu Ulogu**: Kreirajte YAML datoteku (npr. `custom_role.yaml`) koja definiše prilagođenu ulogu. Ova datoteka treba da uključuje dozvolu `cloudkms.cryptoKeyVersions.useToDecryptViaDelegation`. Evo primera kako bi ova datoteka mogla izgledati: ```yaml title: "KMS Decryption via Delegation" description: "Allows decryption via delegation" stage: "GA" includedPermissions: - - "cloudkms.cryptoKeyVersions.useToDecryptViaDelegation" +- "cloudkms.cryptoKeyVersions.useToDecryptViaDelegation" ``` - -2. **Create the Custom Role Using the gcloud CLI**: Use the following command to create the custom role in your Google Cloud project: - +2. **Kreirajte prilagođenu ulogu koristeći gcloud CLI**: Koristite sledeću komandu da kreirate prilagođenu ulogu u vašem Google Cloud projektu: ```bash gcloud iam roles create kms_decryptor_via_delegation --project [YOUR_PROJECT_ID] --file custom_role.yaml ``` +Zamenite `[YOUR_PROJECT_ID]` sa vašim Google Cloud ID-jem projekta. -Replace `[YOUR_PROJECT_ID]` with your Google Cloud project ID. - -3. **Grant the Custom Role to a Service Account**: Assign your custom role to a service account that will be using this permission.

### Networking -- **IP Forwarding**: It's possible to **enable IP forwarding** from the creation of the instance. -- **Hostname**: It's possible to give the instance a permanent hostname. -- **Interface**: It's possible to add a network interface +- **IP Forwarding**: Moguće je **omogućiti IP prosleđivanje** prilikom kreiranja instance. +- **Hostname**: Moguće je dati instanci trajno ime. +- **Interfejs**: Moguće je dodati mrežni interfejs. ### Extra Security -These options will **increase the security** of the VM and are recommended: +Ove opcije će **povećati bezbednost** VM-a i preporučuju se: -- **Secure boot:** Secure boot helps protect your VM instances against boot-level and kernel-level malware and rootkits. -- **Enable vTPM:** Virtual Trusted Platform Module (vTPM) validates your guest VM pre-boot and boot integrity, and offers key generation and protection. -- **Integrity supervision:** Integrity monitoring lets you monitor and verify the runtime boot integrity of your shielded VM instances using Stackdriver reports. Requires vTPM to be enabled. +- **Secure boot:** Secure boot pomaže u zaštiti vaših VM instanci od malware-a na nivou pokretanja i kernel-a i rootkit-a. +- **Enable vTPM:** Virtual Trusted Platform Module (vTPM) validira integritet vašeg gostujućeg VM-a pre pokretanja i tokom pokretanja, i nudi generisanje i zaštitu ključeva. +- **Integrity supervision:** Monitoring integriteta vam omogućava da pratite i verifikujete integritet pokretanja vaših zaštićenih VM instanci koristeći Stackdriver izveštaje. Zahteva da vTPM bude omogućen. ### VM Access -The common way to enable access to the VM is by **allowing certain SSH public keys** to access the VM.\ -However, it's also possible to **enable the access to the VM vial `os-config` service using IAM**. Moreover, it's possible to enable 2FA to access the VM using this service.\ -When this **service** is **enabled**, the access via **SSH keys is disabled.** +Uobičajen način za omogućavanje pristupa VM-u je **dozvoljavanje određenih SSH javnih ključeva** za pristup VM-u.\ +Međutim, takođe je moguće **omogućiti pristup VM-u putem `os-config` servisa koristeći IAM**. Štaviše, moguće je omogućiti 2FA za pristup VM-u koristeći ovaj servis.\ +Kada je ovaj **servis** **omogućen**, pristup putem **SSH ključeva je onemogućen.**
### Metadata -It's possible to define **automation** (userdata in AWS) which are **shell commands** that will be executed every time the machine turns on or restarts. - -It's also possible to **add extra metadata key-value values** that are going to be accessible from the metadata endpoint. This info is commonly used for environment variables and startup/shutdown scripts. This can be obtained using the **`describe` method** from a command in the enumeration section, but it could also be retrieved from the inside of the instance accessing the metadata endpoint. +Moguće je definisati **automaciju** (userdata u AWS) koja su **shell komande** koje će se izvršavati svaki put kada se mašina uključi ili ponovo pokrene. +Takođe je moguće **dodati dodatne ključ-vrednost metapodatke** koji će biti dostupni sa metapodatkovnog krajnjeg tačke. Ove informacije se obično koriste za varijable okruženja i skripte za pokretanje/gašenje. Ovo se može dobiti koristeći **`describe` metodu** iz komande u sekciji enumeracije, ali se takođe može preuzeti iznutra instance pristupajući metapodatkovnom kraju. ```bash # view project metadata curl "http://metadata.google.internal/computeMetadata/v1/project/attributes/?recursive=true&alt=text" \ - -H "Metadata-Flavor: Google" +-H "Metadata-Flavor: Google" # view instance metadata curl "http://metadata.google.internal/computeMetadata/v1/instance/attributes/?recursive=true&alt=text" \ - -H "Metadata-Flavor: Google" +-H "Metadata-Flavor: Google" ``` - -Moreover, **auth token for the attached service account** and **general info** about the instance, network and project is also going to be available from the **metadata endpoint**. For more info check: +Pored toga, **auth token za pridruženi servisni nalog** i **opšte informacije** o instanci, mreži i projektu će takođe biti dostupne sa **metadata endpoint**.

You can also configure what to do when the used CMEF is revoked: Noting or shut down the VM. +Google-om upravljani ključ za enkripciju se koristi po default-u, ali može se konfigurisati ključ za enkripciju koji upravlja kupac (CMEK). Takođe možete konfigurisati šta da radite kada se korišćeni CMEK opozove: Noting ili isključite VM.

Metod `_make_authorization_grant_assertion` otkriva potrebu da se deklarira t**arget workspace user**, nazvan _subject_, za generisanje JWT-ova pod DWD.

Jednostavno rečeno, jedan validan Workspace korisnik je dovoljan za nastavak.\ +Ovaj korisnik može biti definisan u DeleFriend-ovom _config.yaml_ fajlu. Ako ciljani korisnik Workspace-a nije već poznat, alat olakšava automatsku identifikaciju validnih korisnika Workspace-a skeniranjem korisnika domena sa ulogama na GCP projektima. Ključno je napomenuti (ponovo) da su JWT-ovi specifični za domen i ne generišu se za svakog korisnika; stoga, automatski proces cilja jedinstveni identitet po domenu. +7. **Enumerate and create a new bearer access token** za svaki JWT i validirati token protiv tokeninfo API. #### [Gitlab's Python script](https://gitlab.com/gitlab-com/gl-security/threatmanagement/redteam/redteam-public/gcp_misc/-/blob/master/gcp_delegation.py) -Gitlab've created [this Python script](https://gitlab.com/gitlab-com/gl-security/gl-redteam/gcp_misc/blob/master/gcp_delegation.py) that can do two things - list the user directory and create a new administrative account while indicating a json with SA credentials and the user to impersonate.

-1. **Identity creates a JWT:** The Identity uses the service account's private key (part of the JSON key pair file) to sign a JWT. This JWT contains claims about the service account, the target user to impersonate, and the OAuth scopes of access to the REST API which is being requested. -2. **The Identity uses the JWT to request an access token:** The application/user uses the JWT to request an access token from Google's OAuth 2.0 service. The request also includes the target user to impersonate (the user's Workspace email), and the scopes for which access is requested. -3. **Google's OAuth 2.0 service returns an access token:** The access token represents the service account's authority to act on behalf of the user for the specified scopes. This token is typically short-lived and must be refreshed periodically (per the application's need). It's essential to understand that the OAuth scopes specified in the JWT token have validity and impact on the resultant access token. For instance, access tokens possessing multiple scopes will hold validity for numerous REST API applications. -4. **The Identity uses the access token to call Google APIs**: Now with a relevant access token, the service can access the required REST API. The application uses this access token in the "Authorization" header of its HTTP requests destined for Google APIs. These APIs utilize the token to verify the impersonated identity and confirm it has the necessary authorization. -5. **Google APIs return the requested data**: If the access token is valid and the service account has appropriate authorization, the Google APIs return the requested data. For example, in the following picture, we’ve leveraged the _users.messages.list_ method to list all the Gmail message IDs associated with a target Workspace user. +1. **Identitet kreira JWT:** Identitet koristi privatni ključ servisnog naloga (deo JSON datoteke sa ključem) da potpiše JWT. Ovaj JWT sadrži tvrdnje o servisnom nalogu, ciljanom korisniku koga treba impersonirati, i OAuth opsezima pristupa REST API-ju koji se zahteva. +2. **Identitet koristi JWT da zatraži pristupni token:** Aplikacija/korisnik koristi JWT da zatraži pristupni token od Google-ove OAuth 2.0 usluge. Zahtev takođe uključuje ciljanog korisnika koga treba impersonirati (korisnički email Workspace-a), i opsege za koje se traži pristup. +3. **Google-ova OAuth 2.0 usluga vraća pristupni token:** Pristupni token predstavlja ovlašćenje servisnog naloga da deluje u ime korisnika za određene opsege. Ovaj token je obično kratkotrajan i mora se periodično osvežavati (prema potrebama aplikacije). Važno je razumeti da opsezi OAuth navedeni u JWT tokenu imaju validnost i uticaj na rezultantni pristupni token. Na primer, pristupni tokeni koji poseduju više opsega će imati validnost za brojne REST API aplikacije. +4. **Identitet koristi pristupni token da pozove Google API-e**: Sada sa relevantnim pristupnim tokenom, servis može pristupiti potrebnom REST API-ju. Aplikacija koristi ovaj pristupni token u "Authorization" header-u svojih HTTP zahteva namenjenih Google API-ima. Ovi API-ji koriste token da verifikuju impersonirani identitet i potvrde da ima neophodna ovlašćenja. +5. **Google API-e vraćaju tražene podatke**: Ako je pristupni token validan i servisni nalog ima odgovarajuće ovlašćenje, Google API-e vraćaju tražene podatke.

In contrast, AWS presents a broad spectrum of cloud services for a diverse clientele. -2. **Hybrid Cloud Solutions**: Both IBM Cloud and AWS offer hybrid cloud services, allowing integration of on-premises infrastructure with their cloud services. However, the methodology and services provided by each differ. -3. **Artificial Intelligence and Machine Learning (AI & ML)**: IBM Cloud is particularly noted for its extensive and integrated services in AI and ML. AWS also offers AI and ML services, but IBM's solutions are considered more comprehensive and deeply embedded within its cloud platform. -4. **Industry-Specific Solutions**: IBM Cloud is recognized for its focus on particular industries like financial services, healthcare, and government, offering bespoke solutions. AWS caters to a wide array of industries but might not have the same depth in industry-specific solutions as IBM Cloud. +1. **Fokus**: IBM Cloud prvenstveno se obraća klijentima iz preduzeća, pružajući paket usluga dizajniranih za njihove specifične potrebe, uključujući poboljšanu sigurnost i mere usklađenosti. Nasuprot tome, AWS nudi širok spektar cloud usluga za raznoliku klijentelu. +2. **Hibridna Cloud Rešenja**: I IBM Cloud i AWS nude hibridne cloud usluge, omogućavajući integraciju lokalne infrastrukture sa njihovim cloud uslugama. Međutim, metodologija i usluge koje svaka od njih pruža se razlikuju. +3. **Veštačka Inteligencija i Mašinsko Učenje (AI & ML)**: IBM Cloud je posebno poznat po svojim opsežnim i integrisanim uslugama u AI i ML. AWS takođe nudi AI i ML usluge, ali se IBM-ova rešenja smatraju sveobuhvatnijim i dublje integrisanim unutar svoje cloud platforme. +4. **Rešenja Specifična za Industriju**: IBM Cloud je prepoznat po svom fokusu na određene industrije kao što su finansijske usluge, zdravstvena zaštita i vlada, nudeći prilagođena rešenja.

It is designed to provide a high level of security by physically and electronically isolating the cryptographic functions from the rest of the system. +Hardverski bezbednosni modul (HSM) je posvećen kriptografski uređaj koji se koristi za generisanje, skladištenje i upravljanje kriptografskim ključevima i zaštitu osetljivih podataka. Dizajniran je da pruži visok nivo bezbednosti fizički i elektronski izolovanjem kriptografskih funkcija od ostatka sistema. -The way an HSM works can vary depending on the specific model and manufacturer, but generally, the following steps occur: +Način na koji HSM funkcioniše može varirati u zavisnosti od specifičnog modela i proizvođača, ali generalno, sledeći koraci se dešavaju: -1. **Key generation**: The HSM generates a random cryptographic key using a secure random number generator. -2. **Key storage**: The key is **stored securely within the HSM, where it can only be accessed by authorized users or processes**. -3. **Key management**: The HSM provides a range of key management functions, including key rotation, backup, and revocation. -4. **Cryptographic operations**: The HSM performs a range of cryptographic operations, including encryption, decryption, digital signature, and key exchange. These operations are **performed within the secure environment of the HSM**, which protects against unauthorized access and tampering. -5. **Audit logging**: The HSM logs all cryptographic operations and access attempts, which can be used for compliance and security auditing purposes. +1. **Generisanje ključeva**: HSM generiše nasumični kriptografski ključ koristeći siguran generator nasumičnih brojeva. +2. **Skladištenje ključeva**: Ključ je **sigurno smešten unutar HSM-a, gde mu mogu pristupiti samo ovlašćeni korisnici ili procesi**. +3. **Upravljanje ključevima**: HSM pruža niz funkcija upravljanja ključevima, uključujući rotaciju ključeva, rezervnu kopiju i opoziv. +4. **Kriptografske operacije**: HSM obavlja niz kriptografskih operacija, uključujući enkripciju, dekripciju, digitalni potpis i razmenu ključeva. Ove operacije se **izvode unutar sigurnog okruženja HSM-a**, što štiti od neovlašćenog pristupa i manipulacije. +5. **Audit logovanje**: HSM beleži sve kriptografske operacije i pokušaje pristupa, što se može koristiti za usklađenost i bezbednosne revizije. -HSMs can be used for a wide range of applications, including secure online transactions, digital certificates, secure communications, and data encryption. They are often used in industries that require a high level of security, such as finance, healthcare, and government. +HSM se može koristiti za širok spektar aplikacija, uključujući sigurne online transakcije, digitalne sertifikate, sigurnu komunikaciju i enkripciju podataka. Često se koriste u industrijama koje zahtevaju visok nivo bezbednosti, kao što su finansije, zdravstvo i vlada. -Overall, the high level of security provided by HSMs makes it **very difficult to extract raw keys from them, and attempting to do so is often considered a breach of security**. However, there may be **certain scenarios** where a **raw key could be extracted** by authorized personnel for specific purposes, such as in the case of a key recovery procedure. +Sve u svemu, visok nivo bezbednosti koji pružaju HSM čini **veoma teškim da se sirovi ključevi izvade iz njih, a pokušaj da se to uradi često se smatra kršenjem bezbednosti**. Međutim, mogu postojati **određeni scenariji** u kojima bi **sirovi ključ mogao biti izvučen** od strane ovlašćenog osoblja za specifične svrhe, kao što je slučaj procedure oporavka ključeva. {{#include ../../banners/hacktricks-training.md}} - - - - diff --git a/src/pentesting-cloud/ibm-cloud-pentesting/ibm-hyper-protect-virtual-server.md b/src/pentesting-cloud/ibm-cloud-pentesting/ibm-hyper-protect-virtual-server.md index eb99bff8f..3246d718e 100644 --- a/src/pentesting-cloud/ibm-cloud-pentesting/ibm-hyper-protect-virtual-server.md +++ b/src/pentesting-cloud/ibm-cloud-pentesting/ibm-hyper-protect-virtual-server.md @@ -2,45 +2,41 @@ {{#include ../../banners/hacktricks-training.md}} -## Basic Information +## Osnovne informacije -Hyper Protect Virtual Server is a **virtual server** offering from IBM that is designed to provide a **high level of security and compliance** for sensitive workloads.

Some of the key differences are: +U poređenju sa x64 arhitekturom, koja je najčešće korišćena arhitektura u serverima i ličnim računarima, LinuxONE ima neke jedinstvene prednosti. Neke od ključnih razlika su: -1. **Scalability**: LinuxONE can support massive amounts of processing power and memory, which makes it ideal for large-scale workloads. -2. **Security**: LinuxONE has built-in security features that are designed to protect against cyber threats and data breaches. These features include hardware encryption, secure boot, and tamper-proof virtualization. -3. **Reliability**: LinuxONE has built-in redundancy and failover capabilities that help ensure high availability and minimize downtime. -4. **Performance**: LinuxONE can deliver high levels of performance for workloads that require large amounts of processing power, such as big data analytics, machine learning, and AI. +1. **Skalabilnost**: LinuxONE može podržati ogromne količine procesorske snage i memorije, što ga čini idealnim za velika radna opterećenja. +2. **Sigurnost**: LinuxONE ima ugrađene sigurnosne funkcije koje su dizajnirane da štite od sajber pretnji i curenja podataka. Ove funkcije uključuju hardversku enkripciju, sigurno pokretanje i zaštitu od neovlašćenog pristupa. +3. **Pouzdanost**: LinuxONE ima ugrađenu redundanciju i mogućnosti prebacivanja koje pomažu da se osigura visoka dostupnost i minimizira vreme zastoja. +4. **Performanse**: LinuxONE može pružiti visoke nivoe performansi za radna opterećenja koja zahtevaju velike količine procesorske snage, kao što su analitika velikih podataka, mašinsko učenje i AI. -Overall, LinuxONE is a powerful and secure platform that is well-suited for running large-scale, mission-critical workloads that require high levels of performance and reliability. While x64 architecture has its own advantages, it may not be able to provide the same level of scalability, security, and reliability as LinuxONE for certain workloads.\\ +Sve u svemu, LinuxONE je moćna i sigurna platforma koja je dobro prilagođena za pokretanje velikih, radnih opterećenja od kritične važnosti koja zahtevaju visoke nivoe performansi i pouzdanosti. Dok x64 arhitektura ima svoje prednosti, možda neće moći da pruži isti nivo skalabilnosti, sigurnosti i pouzdanosti kao LinuxONE za određena radna opterećenja.\\ {{#include ../../banners/hacktricks-training.md}} - - - - diff --git a/src/pentesting-cloud/kubernetes-security/README.md b/src/pentesting-cloud/kubernetes-security/README.md index 4f7e16ef0..1904d2ffc 100644 --- a/src/pentesting-cloud/kubernetes-security/README.md +++ b/src/pentesting-cloud/kubernetes-security/README.md @@ -2,83 +2,79 @@ {{#include ../../banners/hacktricks-training.md}} -## Kubernetes Basics +## Osnovi Kubernetesa -If you don't know anything about Kubernetes this is a **good start**.

Podrazumevani servisni nalozi u sistemu mogu se enumerisati, svaki povezan sa tajnom. Ove tajne imaju strukturu imena: statički prefiks praćen nasumičnim alfanumeričkim tokenom od pet karaktera (izuzimajući određene karaktere) prema [izvornom kodu](https://github.com/kubernetes/kubernetes/blob/8418cccaf6a7307479f1dfeafb0d2823c1c37802/staging/src/k8s.io/apimachinery/pkg/util/rand/rand.go#L83). -While an attacker in possession of a token with read permissions requires the exact name of the secret to use it, unlike the broader _**listing secrets**_ privilege, there are still vulnerabilities. Default service accounts in the system can be enumerated, each associated with a secret. These secrets have a name structure: a static prefix followed by a random five-character alphanumeric token (excluding certain characters) according to the [source code](https://github.com/kubernetes/kubernetes/blob/8418cccaf6a7307479f1dfeafb0d2823c1c37802/staging/src/k8s.io/apimachinery/pkg/util/rand/rand.go#L83). +Token se generiše iz ograničenog skupa od 27 karaktera (`bcdfghjklmnpqrstvwxz2456789`), umesto iz punog alfanumeričkog opsega. Ova ograničenja smanjuju ukupan broj mogućih kombinacija na 14,348,907 (27^5). Kao rezultat, napadač bi mogao izvesti brute-force napad da bi dedukovao token u roku od nekoliko sati, što bi potencijalno moglo dovesti do eskalacije privilegija pristupom osetljivim servisnim nalozima. -The token is generated from a limited 27-character set (`bcdfghjklmnpqrstvwxz2456789`), rather than the full alphanumeric range. This limitation reduces the total possible combinations to 14,348,907 (27^5). Consequently, an attacker could feasibly execute a brute-force attack to deduce the token in a matter of hours, potentially leading to privilege escalation by accessing sensitive service accounts. +### Zahtevi za potpisivanje sertifikata -### Certificate Signing Requests +Ako imate glagole **`create`** u resursu `certificatesigningrequests` (ili barem u `certificatesigningrequests/nodeClient`).

Unlike Pods that are managed by the control plane (for example, a Deployment); instead, the **kubelet watches each static Pod** (and restarts it if it fails). +_Static Pods_ se direktno upravljaju od strane kubelet demona na određenom čvoru, bez da ih API server posmatra. Za razliku od Podova koji se upravljaju putem kontrolne ravni (na primer, Deployment); umesto toga, **kubelet prati svaki static Pod** (i ponovo ga pokreće ako ne uspe). -Therefore, static Pods are always **bound to one Kubelet** on a specific node. +Stoga, static Pods su uvek **vezani za jedan Kubelet** na određenom čvoru. -The **kubelet automatically tries to create a mirror Pod on the Kubernetes API server** for each static Pod. This means that the Pods running on a node are visible on the API server, but cannot be controlled from there. The Pod names will be suffixed with the node hostname with a leading hyphen. +**Kubelet automatski pokušava da kreira mirror Pod na Kubernetes API serveru** za svaki static Pod. To znači da su Podovi koji se izvršavaju na čvoru vidljivi na API serveru, ali se ne mogu kontrolisati odatle. Imena Podova će imati sufiks sa imenom čvora sa vodećim crticama. > [!CAUTION] -> The **`spec` of a static Pod cannot refer to other API objects** (e.g., ServiceAccount, ConfigMap, Secret, etc. So **you cannot abuse this behaviour to launch a pod with an arbitrary serviceAccount** in the current node to compromise the cluster. But you could use this to run pods in different namespaces (in case thats useful for some reason). +> **`spec` static Pod-a ne može se odnositi na druge API objekte** (npr., ServiceAccount, ConfigMap, Secret, itd.). Dakle, **ne možete zloupotrebiti ovo ponašanje da pokrenete pod sa proizvoljnim serviceAccount** na trenutnom čvoru da kompromitujete klaster. Ali možete to iskoristiti da pokrenete podove u različitim namespace-ima (ako je to iz nekog razloga korisno). -If you are inside the node host you can make it create a **static pod inside itself**. This is pretty useful because it might allow you to **create a pod in a different namespace** like **kube-system**. +Ako ste unutar čvora, možete ga naterati da kreira **static pod unutar sebe**. Ovo je prilično korisno jer bi moglo omogućiti da **kreirate pod u različitom namespace-u** kao što je **kube-system**. -In order to create a static pod, the [**docs are a great help**](https://kubernetes.io/docs/tasks/configure-pod-container/static-pod/). You basically need 2 things: +Da biste kreirali static pod, [**dokumentacija je velika pomoć**](https://kubernetes.io/docs/tasks/configure-pod-container/static-pod/).

On GKE, this will spin up a [Network Load Balancer](https://cloud.google.com/compute/docs/load-balancing/network/) that will give you a single IP address that will forward all traffic to your service. In AWS it will launch a Load Balancer. +Izlaže Servis spolja **koristeći load balancer provajdera u oblaku**. Na GKE, ovo će pokrenuti [Network Load Balancer](https://cloud.google.com/compute/docs/load-balancing/network/) koji će vam dati jedinstvenu IP adresu koja će preusmeriti sav saobraćaj na vaš servis. U AWS-u će pokrenuti Load Balancer. -You have to pay for a LoadBalancer per exposed service, which can be expensive. - -List all LoadBalancers: +Morate plaćati za LoadBalancer po izloženom servisu, što može biti skupo. +Lista svih LoadBalancera: ```bash kubectl get services --all-namespaces -o=custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name,TYPE:.spec.type,CLUSTER-IP:.spec.clusterIP,EXTERNAL-IP:.status.loadBalancer.ingress[*],PORT(S):.spec.ports[*].port,NODEPORT(S):.spec.ports[*].nodePort,TARGETPORT(S):.spec.ports[*].targetPort,SELECTOR:.spec.selector' | grep LoadBalancer ``` - -### External IPs +### Spoljni IP-ovi > [!TIP] -> External IPs are exposed by services of type Load Balancers and they are generally used when an external Cloud Provider Load Balancer is being used. +> Spoljni IP-ovi su izloženi uslugama tipa Load Balancers i obično se koriste kada se koristi spoljni Cloud Provider Load Balancer. > -> For finding them, check for load balancers with values in the `EXTERNAL-IP` field. +> Da biste ih pronašli, proverite load balancere sa vrednostima u polju `EXTERNAL-IP`. -Traffic that ingresses into the cluster with the **external IP** (as **destination IP**), on the Service port, will be **routed to one of the Service endpoints**. `externalIPs` are not managed by Kubernetes and are the responsibility of the cluster administrator. - -In the Service spec, `externalIPs` can be specified along with any of the `ServiceTypes`. In the example below, "`my-service`" can be accessed by clients on "`80.11.12.10:80`" (`externalIP:port`) +Saobraćaj koji ulazi u klaster sa **spoljnim IP-om** (kao **odredišni IP**), na portu usluge, biće **usmeren na jedan od krajnjih tačaka usluge**. `externalIPs` nisu upravljani od strane Kubernetesa i odgovornost su administratora klastera. +U specifikaciji usluge, `externalIPs` se mogu navesti zajedno sa bilo kojim od `ServiceTypes`. U sledećem primeru, "`my-service`" može biti pristupljeno od strane klijenata na "`80.11.12.10:80`" (`externalIP:port`) ```yaml apiVersion: v1 kind: Service metadata: - name: my-service +name: my-service spec: - selector: - app: MyApp - ports: - - name: http - protocol: TCP - port: 80 - targetPort: 9376 - externalIPs: - - 80.11.12.10 +selector: +app: MyApp +ports: +- name: http +protocol: TCP +port: 80 +targetPort: 9376 +externalIPs: +- 80.11.12.10 ``` - ### ExternalName -[**From the docs:**](https://kubernetes.io/docs/concepts/services-networking/service/#externalname) Services of type ExternalName **map a Service to a DNS name**, not to a typical selector such as `my-service` or `cassandra`. You specify these Services with the `spec.externalName` parameter. - -This Service definition, for example, maps the `my-service` Service in the `prod` namespace to `my.database.example.com`: +[**Iz dokumenata:**](https://kubernetes.io/docs/concepts/services-networking/service/#externalname) Servisi tipa ExternalName **mapiraju servis na DNS ime**, a ne na tipičan selektor kao što je `my-service` ili `cassandra`. Ove servise definišete pomoću parametra `spec.externalName`. +Ova definicija servisa, na primer, mapira `my-service` servis u `prod` imenskom prostoru na `my.database.example.com`: ```yaml apiVersion: v1 kind: Service metadata: - name: my-service - namespace: prod +name: my-service +namespace: prod spec: - type: ExternalName - externalName: my.database.example.com +type: ExternalName +externalName: my.database.example.com ``` +Kada se traži host `my-service.prod.svc.cluster.local`, klasterska DNS usluga vraća `CNAME` zapis sa vrednošću `my.database.example.com`. Pristup `my-service` funkcioniše na isti način kao i drugi servisi, ali sa ključnom razlikom da **preusmeravanje se dešava na DNS nivou** umesto putem proksiranja ili prosleđivanja. -When looking up the host `my-service.prod.svc.cluster.local`, the cluster DNS Service returns a `CNAME` record with the value `my.database.example.com`. Accessing `my-service` works in the same way as other Services but with the crucial difference that **redirection happens at the DNS level** rather than via proxying or forwarding. - -List all ExternalNames: - +Lista svih ExternalNames: ```bash kubectl get services --all-namespaces | grep ExternalName ``` - ### Ingress -Unlike all the above examples, **Ingress is NOT a type of service**. Instead, it sits **in front of multiple services and act as a “smart router”** or entrypoint into your cluster. +Za razliku od svih gore navedenih primera, **Ingress NIJE tip usluge**. Umesto toga, on se nalazi **ispred više usluga i deluje kao “pametni ruter”** ili ulazna tačka u vaš klaster. -You can do a lot of different things with an Ingress, and there are **many types of Ingress controllers that have different capabilities**. +Možete raditi mnogo različitih stvari sa Ingress-om, i postoje **mnogi tipovi Ingress kontrolera koji imaju različite mogućnosti**. -The default GKE ingress controller will spin up a [HTTP(S) Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) for you. This will let you do both path based and subdomain based routing to backend services. For example, you can send everything on foo.yourdomain.com to the foo service, and everything under the yourdomain.com/bar/ path to the bar service. - -The YAML for a Ingress object on GKE with a [L7 HTTP Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) might look like this: +Podrazumevani GKE ingress kontroler će pokrenuti [HTTP(S) Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) za vas. Ovo će vam omogućiti da radite i rutiranje zasnovano na putanjama i poddomenima ka pozadinskim uslugama. Na primer, možete poslati sve na foo.yourdomain.com ka foo usluzi, i sve pod putanjom yourdomain.com/bar/ ka bar usluzi. +YAML za Ingress objekat na GKE sa [L7 HTTP Load Balancer](https://cloud.google.com/compute/docs/load-balancing/http/) može izgledati ovako: ```yaml apiVersion: extensions/v1beta1 kind: Ingress metadata: - name: my-ingress +name: my-ingress spec: - backend: - serviceName: other - servicePort: 8080 - rules: - - host: foo.mydomain.com - http: - paths: - - backend: - serviceName: foo - servicePort: 8080 - - host: mydomain.com - http: - paths: - - path: /bar/* - backend: - serviceName: bar - servicePort: 8080 +backend: +serviceName: other +servicePort: 8080 +rules: +- host: foo.mydomain.com +http: +paths: +- backend: +serviceName: foo +servicePort: 8080 +- host: mydomain.com +http: +paths: +- path: /bar/* +backend: +serviceName: bar +servicePort: 8080 ``` - -List all the ingresses: - +Списак свих улаза: ```bash kubectl get ingresses --all-namespaces -o=custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name,RULES:spec.rules[*],STATUS:status' ``` - -Although in this case it's better to get the info of each one by one to read it better: - +Iako je u ovom slučaju bolje dobiti informacije o svakom pojedinačno kako bi se bolje pročitali: ```bash kubectl get ingresses --all-namespaces -o=yaml ``` - ### References - [https://medium.com/google-cloud/kubernetes-nodeport-vs-loadbalancer-vs-ingress-when-should-i-use-what-922f010849e0](https://medium.com/google-cloud/kubernetes-nodeport-vs-loadbalancer-vs-ingress-when-should-i-use-what-922f010849e0) - [https://kubernetes.io/docs/concepts/services-networking/service/](https://kubernetes.io/docs/concepts/services-networking/service/) {{#include ../../banners/hacktricks-training.md}} - - - - diff --git a/src/pentesting-cloud/kubernetes-security/kubernetes-basics.md b/src/pentesting-cloud/kubernetes-security/kubernetes-basics.md index f4e4ed9e0..676438ccf 100644 --- a/src/pentesting-cloud/kubernetes-security/kubernetes-basics.md +++ b/src/pentesting-cloud/kubernetes-security/kubernetes-basics.md @@ -1,94 +1,93 @@ -# Kubernetes Basics +# Osnovi Kubernetesa -## Kubernetes Basics +## Osnovi Kubernetesa {{#include ../../banners/hacktricks-training.md}} -**The original author of this page is** [**Jorge**](https://www.linkedin.com/in/jorge-belmonte-a924b616b/) **(read his original post** [**here**](https://sickrov.github.io)**)** +**Originalni autor ove stranice je** [**Jorge**](https://www.linkedin.com/in/jorge-belmonte-a924b616b/) **(pročitajte njegov originalni post** [**ovde**](https://sickrov.github.io)**)** -## Architecture & Basics +## Arhitektura i Osnovi -### What does Kubernetes do? +### Šta radi Kubernetes? -- Allows running container/s in a container engine. -- Schedule allows containers mission efficient. -- Keep containers alive. -- Allows container communications. -- Allows deployment techniques. -- Handle volumes of information. +- Omogućava pokretanje kontejnera u kontejnerskom motoru. +- Raspoređuje kontejnerske misije efikasno. +- Održava kontejnere aktivnim. +- Omogućava komunikaciju između kontejnera. +- Omogućava tehnike implementacije. +- Rukuje obimima informacija. -### Architecture +### Arhitektura ![](https://sickrov.github.io/media/Screenshot-68.jpg) -- **Node**: operating system with pod or pods. - - **Pod**: Wrapper around a container or multiple containers with. A pod should only contain one application (so usually, a pod run just 1 container). The pod is the way kubernetes abstracts the container technology running. - - **Service**: Each pod has 1 internal **IP address** from the internal range of the node. However, it can be also exposed via a service. The **service has also an IP address** and its goal is to maintain the communication between pods so if one dies the **new replacement** (with a different internal IP) **will be accessible** exposed in the **same IP of the service**. It can be configured as internal or external. The service also actuates as a **load balancer when 2 pods are connected** to the same service.\ - When a **service** is **created** you can find the endpoints of each service running `kubectl get endpoints` -- **Kubelet**: Primary node agent. The component that establishes communication between node and kubectl, and only can run pods (through API server). The kubelet doesn’t manage containers that were not created by Kubernetes. -- **Kube-proxy**: is the service in charge of the communications (services) between the apiserver and the node. The base is an IPtables for nodes. Most experienced users could install other kube-proxies from other vendors. -- **Sidecar container**: Sidecar containers are the containers that should run along with the main container in the pod. This sidecar pattern extends and enhances the functionality of current containers without changing them. Nowadays, We know that we use container technology to wrap all the dependencies for the application to run anywhere. A container does only one thing and does that thing very well. -- **Master process:** - - **Api Server:** Is the way the users and the pods use to communicate with the master process. Only authenticated request should be allowed. - - **Scheduler**: Scheduling refers to making sure that Pods are matched to Nodes so that Kubelet can run them. It has enough intelligence to decide which node has more available resources the assign the new pod to it. Note that the scheduler doesn't start new pods, it just communicate with the Kubelet process running inside the node, which will launch the new pod. - - **Kube Controller manager**: It checks resources like replica sets or deployments to check if, for example, the correct number of pods or nodes are running. In case a pod is missing, it will communicate with the scheduler to start a new one. It controls replication, tokens, and account services to the API. - - **etcd**: Data storage, persistent, consistent, and distributed. Is Kubernetes’s database and the key-value storage where it keeps the complete state of the clusters (each change is logged here). Components like the Scheduler or the Controller manager depends on this date to know which changes have occurred (available resourced of the nodes, number of pods running...) -- **Cloud controller manager**: Is the specific controller for flow controls and applications, i.e: if you have clusters in AWS or OpenStack. +- **Čvor**: operativni sistem sa podom ili podovima. +- **Pod**: Omotač oko kontejnera ili više kontejnera. Pod bi trebao sadržati samo jednu aplikaciju (tako da obično, pod pokreće samo 1 kontejner). Pod je način na koji Kubernetes apstrahuje tehnologiju kontejnera koja se pokreće. +- **Servis**: Svaki pod ima 1 internu **IP adresu** iz unutrašnjeg opsega čvora. Međutim, može biti izložen i putem servisa. **Servis takođe ima IP adresu** i njegov cilj je održavanje komunikacije između podova, tako da ako jedan umre, **novi zamenski** (sa drugačijom internom IP) **će biti dostupan** izložen na **isto IP servisa**. Može biti konfigurisan kao unutrašnji ili spoljašnji. Servis takođe deluje kao **balansirnik opterećenja kada su 2 poda povezana** na isti servis.\ +Kada je **servis** **kreiran**, možete pronaći krajnje tačke svakog servisa pokretanjem `kubectl get endpoints` +- **Kubelet**: Primarni agent čvora. Komponenta koja uspostavlja komunikaciju između čvora i kubectl, i može pokretati samo podove (putem API servera). Kubelet ne upravlja kontejnerima koji nisu kreirani od strane Kubernetesa. +- **Kube-proxy**: je servis zadužen za komunikaciju (servise) između apiservera i čvora. Osnova je IPtables za čvorove. Najiskusniji korisnici mogu instalirati druge kube-proxy-e od drugih dobavljača. +- **Sidecar kontejner**: Sidecar kontejneri su kontejneri koji bi trebali raditi zajedno sa glavnim kontejnerom u podu. Ovaj sidecar obrazac proširuje i poboljšava funkcionalnost trenutnih kontejnera bez njihovog menjanja. Danas znamo da koristimo tehnologiju kontejnera da obavijemo sve zavisnosti za aplikaciju da bi radila bilo gde. Kontejner radi samo jednu stvar i radi tu stvar veoma dobro. +- **Glavni proces:** +- **Api Server:** Je način na koji korisnici i podovi komuniciraju sa glavnim procesom. Samo autentifikovani zahtevi bi trebali biti dozvoljeni. +- **Raspoređivač**: Raspoređivanje se odnosi na osiguranje da su podovi usklađeni sa čvorovima kako bi Kubelet mogao da ih pokrene. Ima dovoljno inteligencije da odluči koji čvor ima više dostupnih resursa i dodeli novi pod njemu. Imajte na umu da raspoređivač ne pokreće nove podove, samo komunicira sa Kubelet procesom koji se pokreće unutar čvora, koji će pokrenuti novi pod. +- **Kube Controller menadžer**: Proverava resurse kao što su replikacione grupe ili implementacije da proveri da li, na primer, ispravan broj podova ili čvorova radi. U slučaju da nedostaje pod, komuniciraće sa raspoređivačem da pokrene novi. Kontroliše replikaciju, tokene i usluge računa za API. +- **etcd**: Skladište podataka, postojano, konzistentno i distribuirano. To je baza podataka Kubernetesa i skladište ključ-vrednost gde čuva potpuno stanje klastera (svaka promena se ovde beleži). Komponente kao što su Raspoređivač ili Menadžer kontrolera zavise od ovih podataka da bi znale koje su promene nastale (dostupni resursi čvorova, broj pokrenutih podova...) +- **Cloud controller menadžer**: Specifični je kontroler za tokove kontrole i aplikacije, tj: ako imate klastere u AWS-u ili OpenStack-u. -Note that as the might be several nodes (running several pods), there might also be several master processes which their access to the Api server load balanced and their etcd synchronized. +Imajte na umu da kako može biti nekoliko čvorova (koji pokreću nekoliko podova), može biti i nekoliko glavnih procesa čiji je pristup API serveru balansiran opterećenjem i njihov etcd sinhronizovan. -**Volumes:** +**Obim:** -When a pod creates data that shouldn't be lost when the pod disappear it should be stored in a physical volume. **Kubernetes allow to attach a volume to a pod to persist the data**. The volume can be in the local machine or in a **remote storage**. If you are running pods in different physical nodes you should use a remote storage so all the pods can access it. +Kada pod kreira podatke koji ne bi trebali biti izgubljeni kada pod nestane, trebali bi biti smešteni u fizički obim. **Kubernetes omogućava povezivanje obima sa podom kako bi se podaci sačuvali**. Obim može biti na lokalnoj mašini ili u **daljinskom skladištu**. Ako pokrećete podove na različitim fizičkim čvorovima, trebali biste koristiti daljinsko skladište kako bi svi podovi mogli da mu pristupe. -**Other configurations:** +**Druge konfiguracije:** -- **ConfigMap**: You can configure **URLs** to access services. The pod will obtain data from here to know how to communicate with the rest of the services (pods). Note that this is not the recommended place to save credentials! -- **Secret**: This is the place to **store secret data** like passwords, API keys... encoded in B64. The pod will be able to access this data to use the required credentials. -- **Deployments**: This is where the components to be run by kubernetes are indicated. A user usually won't work directly with pods, pods are abstracted in **ReplicaSets** (number of same pods replicated), which are run via deployments. Note that deployments are for **stateless** applications. The minimum configuration for a deployment is the name and the image to run. -- **StatefulSet**: This component is meant specifically for applications like **databases** which needs to **access the same storage**. -- **Ingress**: This is the configuration that is use to **expose the application publicly with an URL**. Note that this can also be done using external services, but this is the correct way to expose the application. - - If you implement an Ingress you will need to create **Ingress Controllers**. The Ingress Controller is a **pod** that will be the endpoint that will receive the requests and check and will load balance them to the services. the ingress controller will **send the request based on the ingress rules configured**. Note that the ingress rules can point to different paths or even subdomains to different internal kubernetes services. - - A better security practice would be to use a cloud load balancer or a proxy server as entrypoint to don't have any part of the Kubernetes cluster exposed. - - When request that doesn't match any ingress rule is received, the ingress controller will direct it to the "**Default backend**".

A special supplemental group that applies to all containers in a pod. Some volume types allow the Kubelet to change the ownership of that volume to be owned by the pod:
1. The owning GID will be the FSGroup
2. The setgid bit is set (new files created in the volume will be owned by FSGroup)
3. The permission bits are OR'd with rw-rw---- If unset, the Kubelet will not modify the ownership and permissions of any volume

fsGroup
integer

|

Specijalna dopunska grupa koja se primenjuje na sve kontejnere u podu. Neki tipovi volumena omogućavaju Kubelet-u da promeni vlasništvo tog volumena da bude u vlasništvu poda:
1. Vlasnički GID će biti FSGroup
2. Setgid bit je postavljen (nove datoteke kreirane u volumenu će biti u vlasništvu FSGroup)
3. Bitovi dozvola su OR'd sa rw-rw---- Ako nije postavljeno, Kubelet neće menjati vlasništvo i dozvole bilo kog volumena

Konkretno, otvara mogućnost da **maliciozni kontejner** izvrši **ARP spoofing napad** na druge kontejnere smeštene na istom čvoru. Tokom takvog napada, maliciozni kontejner može obmanjujuće presresti ili izmeniti mrežni saobraćaj namenjen drugim kontejnerima. -ARP spoofing attacks involve the **attacker sending falsified ARP** (Address Resolution Protocol) messages over a local area network. This results in the linking of the **attacker's MAC address with the IP address of a legitimate computer or server on the network**. Post successful execution of such an attack, the attacker can intercept, modify, or even stop data in-transit. The attack is executed on Layer 2 of the OSI model, which is why the default connectivity in Kubernetes at this layer raises security concerns. +ARP spoofing napadi uključuju **napadača koji šalje lažne ARP** (Address Resolution Protocol) poruke preko lokalne mreže. To rezultira povezivanjem **MAC adrese napadača sa IP adresom legitimnog računara ili servera na mreži**. Nakon uspešnog izvršenja takvog napada, napadač može presresti, izmeniti ili čak zaustaviti podatke u tranzitu. Napad se izvršava na Sloju 2 OSI modela, zbog čega podrazumevana povezanost u Kubernetes-u na ovom sloju izaziva bezbednosne brige. -In the scenario 4 machines are going to be created: - -- ubuntu-pe: Privileged machine to escape to the node and check metrics (not needed for the attack) -- **ubuntu-attack**: **Malicious** container in default namespace -- **ubuntu-victim**: **Victim** machine in kube-system namespace -- **mysql**: **Victim** machine in default namespace +U scenariju će biti kreirane 4 mašine: +- ubuntu-pe: Privilegovana mašina za bekstvo na čvor i proveru metrika (nije potrebna za napad) +- **ubuntu-attack**: **Maliciozni** kontejner u podrazumevanom imenskom prostoru +- **ubuntu-victim**: **Žrtva** mašina u kube-system imenskom prostoru +- **mysql**: **Žrtva** mašina u podrazumevanom imenskom prostoru ```yaml echo 'apiVersion: v1 kind: Pod metadata: - name: ubuntu-pe +name: ubuntu-pe spec: - containers: - - image: ubuntu - command: - - "sleep" - - "360000" - imagePullPolicy: IfNotPresent - name: ubuntu-pe - securityContext: - allowPrivilegeEscalation: true - privileged: true - runAsUser: 0 - volumeMounts: - - mountPath: /host - name: host-volume - restartPolicy: Never - hostIPC: true - hostNetwork: true - hostPID: true - volumes: - - name: host-volume - hostPath: - path: / +containers: +- image: ubuntu +command: +- "sleep" +- "360000" +imagePullPolicy: IfNotPresent +name: ubuntu-pe +securityContext: +allowPrivilegeEscalation: true +privileged: true +runAsUser: 0 +volumeMounts: +- mountPath: /host +name: host-volume +restartPolicy: Never +hostIPC: true +hostNetwork: true +hostPID: true +volumes: +- name: host-volume +hostPath: +path: / --- apiVersion: v1 kind: Pod metadata: - name: ubuntu-attack - labels: - app: ubuntu +name: ubuntu-attack +labels: +app: ubuntu spec: - containers: - - image: ubuntu - command: - - "sleep" - - "360000" - imagePullPolicy: IfNotPresent - name: ubuntu-attack - restartPolicy: Never +containers: +- image: ubuntu +command: +- "sleep" +- "360000" +imagePullPolicy: IfNotPresent +name: ubuntu-attack +restartPolicy: Never --- apiVersion: v1 kind: Pod metadata: - name: ubuntu-victim - namespace: kube-system +name: ubuntu-victim +namespace: kube-system spec: - containers: - - image: ubuntu - command: - - "sleep" - - "360000" - imagePullPolicy: IfNotPresent - name: ubuntu-victim - restartPolicy: Never +containers: +- image: ubuntu +command: +- "sleep" +- "360000" +imagePullPolicy: IfNotPresent +name: ubuntu-victim +restartPolicy: Never --- apiVersion: v1 kind: Pod metadata: - name: mysql +name: mysql spec: - containers: - - image: mysql:5.6 - ports: - - containerPort: 3306 - imagePullPolicy: IfNotPresent - name: mysql - env: - - name: MYSQL_ROOT_PASSWORD - value: mysql - restartPolicy: Never' | kubectl apply -f - +containers: +- image: mysql:5.6 +ports: +- containerPort: 3306 +imagePullPolicy: IfNotPresent +name: mysql +env: +- name: MYSQL_ROOT_PASSWORD +value: mysql +restartPolicy: Never' | kubectl apply -f - ``` ```bash @@ -97,33 +96,31 @@ kubectl exec -it ubuntu-attack -- bash -c "apt update; apt install -y net-tools kubectl exec -it ubuntu-victim -n kube-system -- bash -c "apt update; apt install -y net-tools curl netcat mysql-client; bash" kubectl exec -it mysql bash -- bash -c "apt update; apt install -y net-tools; bash" ``` +## Osnovno Kubernetes Mrežno Povezivanje -## Basic Kubernetes Networking - -If you want more details about the networking topics introduced here, go to the references. +Ako želite više detalja o mrežnim temama predstavljenim ovde, pogledajte reference. ### ARP -Generally speaking, **pod-to-pod networking inside the node** is available via a **bridge** that connects all pods. This bridge is called “**cbr0**”. (Some network plugins will install their own bridge.) The **cbr0 can also handle ARP** (Address Resolution Protocol) resolution.

Ovaj most se zove “**cbr0**”. (Neki mrežni dodaci će instalirati svoj vlastiti most.) **cbr0 takođe može obraditi ARP** (Protokol za rešavanje adresa) rezoluciju.

First of all you need to [create an OIDC provider for the cluster](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html). -2. Then you create an IAM role with the permissions the SA will require. -3. Create a [trust relationship between the IAM role and the SA](https://docs.aws.amazon.com/eks/latest/userguide/associate-service-account-role.html) name (or the namespaces giving access to the role to all the SAs of the namespace). _The trust relationship will mainly check the OIDC provider name, the namespace name and the SA name_. -4. Finally, **create a SA with an annotation indicating the ARN of the role**, and the pods running with that SA will have **access to the token of the role**. The **token** is **written** inside a file and the path is specified in **`AWS_WEB_IDENTITY_TOKEN_FILE`** (default: `/var/run/secrets/eks.amazonaws.com/serviceaccount/token`) +Ovo je **preporučeni način od strane AWS**. +1. Prvo treba da [napravite OIDC provajder za klaster](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html). +2. Zatim kreirate IAM ulogu sa dozvolama koje će SA zahtevati. +3. Napravite [odnos poverenja između IAM uloge i SA](https://docs.aws.amazon.com/eks/latest/userguide/associate-service-account-role.html) imenom (ili imenom prostora imena koje daje pristup ulozi svim SA-ima u prostoru imena). _Odnos poverenja će uglavnom proveravati ime OIDC provajdera, ime prostora imena i ime SA_. +4. Na kraju, **napravite SA sa anotacijom koja označava ARN uloge**, a podovi koji se pokreću sa tom SA će imati **pristup tokenu uloge**. **Token** je **napisan** unutar datoteke i putanja je specificirana u **`AWS_WEB_IDENTITY_TOKEN_FILE`** (podrazumevano: `/var/run/secrets/eks.amazonaws.com/serviceaccount/token`) ```bash # Create a service account with a role cat >my-service-account.yaml < [!WARNING] -> As an attacker, if you can enumerate a K8s cluster, check for **service accounts with that annotation** to **escalate to AWS**.

The main difference is the overall architecture and how builds are managed inside an openshift (or kubernetes) cluster. +Fundamentalno, gotovo sve iza kulisa funkcioniše isto kao i redovna Jenkins instanca koja radi u VM-u. Glavna razlika je u ukupnoj arhitekturi i načinu na koji se izgradnje upravljaju unutar Openshift (ili Kubernetes) klastera. -### Builds +### Izgradnje -When a build is triggered, it is first managed/orchestrated by the Jenkins master node then delegated to an agent/slave/worker. In this context, the master node is just a regular pod running in a namespace (which might be different that the one where workers run). The same applies for the workers/slaves, however they destroyed once the build finished whereas the master always stays up. Your build is usually run inside a pod, using a default pod template defined by the Jenkins admins. +Kada se izgradnja pokrene, prvo njome upravlja/orchestrira Jenkins master čvor, a zatim se delegira agentu/slavi/radniku. U ovom kontekstu, master čvor je samo redovni pod koji radi u namespace-u (koji može biti različit od onog gde radnici rade). Isto važi i za radnike/slave, međutim oni se uništavaju kada se izgradnja završi, dok master uvek ostaje aktivan. Vaša izgradnja se obično pokreće unutar poda, koristeći pod šablon koji su definisali Jenkins administratori. -### Triggering a build +### Pokretanje izgradnje -You have multiples main ways to trigger a build such as: +Imate više glavnih načina za pokretanje izgradnje, kao što su: -1.

Omogućava vam da ponovo pokrenete prethodno izvršenu izgradnju dok vam omogućava da ažurirate groovy skriptu. Ovo zahteva privilegije na Jenkins folderu i unapred definisanu pipeline.
