A flaw has been found in poco-ai poco-claw up to 0.5.4. Affected is the function get_workspace_file of the file executor_manager/app/api/v1/workspace.py of the component Workspace API. Executing a manipulation of the argument user_id can lead to authorization bypass. The attack may be launched remotely. The exploit has been published and may be used. This patch is called 67fcc88505c57f77d3fcf04eb5b89425b10cbf48. Upgrading the affected component is recommended.
Weakness
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
Potential Mitigations
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
