CVE-2024-8995
Authorization Code issued for Deleted User reuse in Multiple WSO2 Products Allows Unauthorized Access
Overview
Description
Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused. If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead to unauthorized access to sensitive resources and services, contingent on the scopes originally authorized for the compromised authorization code.

| CVSS 3.1 | MEDIUM | MITRE-CVE |
Solution
Invalidate or remove authorization codes for deleted users to prevent reuse.
- Invalidate authorization codes upon user deletion.
- Implement a process to periodically clean old codes.
- Review and enforce access controls for code usage.
- Ensure client credentials are not exposed.
