Synopsis

Amazon Cognito Insecure Permissions

Description

Amazon Cognito is a cloud product from Amazon Web Services (AWS) which provides user authentication, authorization and management services for web and mobile applications. By using Amazon Cognito, developers can quickly add a user management feature to their applications, control and enforce permissions on these users by defining roles, or federate identities from external identity providers.

When configured with an identity pool ID, Amazon Cognito allows a remote unauthenticated user to retrieve temporary AWS credentials related to the Cognito role to be used against the target application AWS account. Depending on the permissions attached to the role, an attacker could leverage these credentials to gain access to sensitive information, or perform arbitrary modifications on the other cloud assets of the target AWS account.

Solution

Review the permissions set on the policy used by the Cognito role to ensure that they follow the least privilege principle and do not grant excessive permissions based on the application needs.
