An authenticated privilege escalation vulnerability in AWS Ops Wheel allows remote users to gain deployment administrator access by manipulating Cognito User Pool attributes.

The vulnerability involves improper control of dynamically-determined object attributes. An authenticated user can leverage a crafted UpdateUserAttributes API call to modify the custom:deployment_admin attribute, effectively granting themselves unauthorized administrative control over user accounts.

With a CVSS score of 8.8, this vulnerability poses a significant threat to cloud administrative integrity. Successful exploitation leads to full unauthorized administrative access, allowing an attacker to manipulate user accounts, access sensitive cloud resources, and potentially compromise the entire deployment environment.

Immediate Action: Update AWS Ops Wheel to the version containing the fix for PR #165 or apply the vendor-recommended security patch immediately.

Proactive Monitoring: Audit CloudTrail and Cognito logs for any UpdateUserAttributes API calls that modify custom attributes, specifically looking for unauthorized changes to deployment_admin flags.

Compensating Controls: Implement strict IAM policies to restrict the permissions of standard users, preventing them from accessing or modifying sensitive Cognito user attributes.

Public Exploit Available: false

Privilege escalation vulnerabilities are critical in cloud environments. Administrators must audit current Cognito configurations and apply the necessary updates to Ops Wheel to prevent unauthorized administrative takeover.
