## Technical details

The vulnerability is a missing authorization check (CWE-862) in the password update functionality at /admin/edit_user_account.php. The application authenticates the user's session but fails to verify whether the authenticated user has permission to modify the target account specified by the id parameter. An authenticated CIT user can craft a POST request targeting any account (e.g., id=4 for admin) and the server will process it without authorization validation. This allows privilege escalation from a low-privileged role to administrator by resetting the admin password. The attack requires valid authentication credentials but no elevated privileges, and is exploitable via network access to the application.
