Description Preview
Overview
This vulnerability affects Redmine project management web application versions 4.2.0 and 4.2.1. The issue occurs in the session management functionality related to two-factor authentication implementation. When a user enables two-factor authentication for their account, any existing sessions for that user continue to remain active instead of being terminated. This creates a security gap where sessions that were established before the stronger authentication requirement was implemented can still access the account, effectively bypassing the added security measure. An attacker who has gained unauthorized access to a user's session could continue to maintain access even after the legitimate user enables 2FA protection.
Remediation
Organizations should upgrade to a patched version of Redmine as recommended by the vendor. The vulnerability has been addressed in subsequent releases. If immediate upgrading is not possible, administrators should consider the following temporary mitigations:
- Manually terminate all active sessions after enabling 2FA for any user account
- Monitor user sessions closely for any suspicious activity
- Implement additional network-level security controls to restrict access to the Redmine instance
- Educate users about the importance of using secure and private devices when accessing Redmine
For users enabling 2FA, it is recommended to log out of all sessions on all devices immediately after enabling 2FA to ensure no unauthorized sessions remain active.
