A Time-of-check Time-of-use (TOCTOU) Race Condition exists in ZoneMinder through 1.32.3 as a session remains active for an authenticated user even after deletion from the users table. This allows a nonexistent user to access and modify records (add/delete Monitors, Users, etc.).
Weakness
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check.
