| Title | SourceCodester Computer Laboratory Management System (PHP LMS) 1.0 Improper Authorization |
|---|
| Description | A broken access control vulnerability exists in the PHP LMS application.
The application fails to enforce proper authorization checks in the save_users function located in classes/Users.php. The backend directly trusts the user-supplied id parameter when updating user records.
An authenticated low-privileged user can modify arbitrary user accounts, including administrator accounts, by manipulating the id parameter in a POST request to /classes/Users.php?f=save.
This can lead to privilege escalation and full administrative account takeover. |
