# AWS - Cognito Enum
|
||||
|
||||
{{#include ../../../../banners/hacktricks-training.md}}
|
||||
|
||||
## Cognito
|
||||
|
||||
Amazon Cognito is utilized for **authentication, authorization, and user management** in web and mobile applications. It allows users the flexibility to sign in either directly using a **user name and password** or indirectly through a **third party**, including Facebook, Amazon, Google, or Apple.
|
||||
|
||||
Central to Amazon Cognito are two primary components:
|
||||
|
||||
1. **User Pools**: These are directories designed for your app users, offering **sign-up and sign-in functionalities**.
|
||||
2. **Identity Pools**: These pools are instrumental in **authorizing users to access different AWS services**. They are not directly involved in the sign-in or sign-up process but are crucial for resource access post-authentication.
|
||||
|
||||
### **User pools**

### **Identity pools**

|

|
||||
## Enumeration
|
||||
|
||||
```bash
|
||||
# List Identity Pools
|
||||
aws cognito-identity list-identity-pools --max-results 60
|
||||
aws cognito-identity describe-identity-pool --identity-pool-id "eu-west-2:38b294756-2578-8246-9074-5367fc9f5367"
|
||||
aws cognito-identity list-identities --identity-pool-id <ident-pool-id> --max-results 60
|
||||
aws cognito-identity get-identity-pool-roles --identity-pool-id <ident-pool-id>
|
||||
|
||||
# Identities Datasets
|
||||
## Get dataset of identity id (inside identity pool)
|
||||
aws cognito-sync list-datasets --identity-pool-id <ident-pool-id> --identity-id <ident-id>
|
||||
## Get info of the dataset
|
||||
aws cognito-sync describe-dataset --identity-pool-id <value> --identity-id <value> --dataset-name <value>
|
||||
## Get dataset records
|
||||
aws cognito-sync list-records --identity-pool-id <value> --identity-id <value> --dataset-name <value>
|
||||
|
||||
# User Pools
|
||||
## Get pools
|
||||
aws cognito-idp list-user-pools --max-results 60
|
||||
|
||||
## Get users
|
||||
aws cognito-idp list-users --user-pool-id <user-pool-id>
|
||||
|
||||
## Get groups
|
||||
aws cognito-idp list-groups --user-pool-id <user-pool-id>
|
||||
|
||||
## Get users in a group
|
||||
aws cognito-idp list-users-in-group --user-pool-id <user-pool-id> --group-name <group-name>
|
||||
|
||||
## List App IDs of a user pool
|
||||
aws cognito-idp list-user-pool-clients --user-pool-id <user-pool-id>
|
||||
|
||||
## List configured identity providers for a user pool
|
||||
aws cognito-idp list-identity-providers --user-pool-id <user-pool-id>
|
||||
|
||||
## List user import jobs
|
||||
aws cognito-idp list-user-import-jobs --user-pool-id <user-pool-id> --max-results 60
|
||||
|
||||
## Get MFA config of a user pool
|
||||
aws cognito-idp get-user-pool-mfa-config --user-pool-id <user-pool-id>
|
||||
|
||||
## Get risk configuration
|
||||
aws cognito-idp describe-risk-configuration --user-pool-id <user-pool-id>
|
||||
```
|
||||
|
||||
### Identity Pools - Unauthenticated Enumeration
|
||||
|
||||
Just **knowing the Identity Pool ID** you might be able **get credentials of the role associated to unauthenticated** users (if any). [**Check how here**](cognito-identity-pools.md#accessing-iam-roles).
|
||||
|
||||
### User Pools - Unauthenticated Enumeration
|
||||
|
||||
Even if you **don't know a valid username** inside Cognito, you might be able to **enumerate** valid **usernames**, **BF** the **passwords** of even **register a new user** just **knowing the App client ID** (which is usually found in source code). [**Check how here**](cognito-user-pools.md#registration)**.**
