|---|
| Description | The affected authentication logic is in `Front-end/server.php:2,40-122`. The application starts or accepts a PHP session before credential verification with `session_start()`. Both successful login branches then assign `$_SESSION['name']` and `$_SESSION['email']` without calling `session_regenerate_id(true)`. Under PHP configurations that accept client-selected session identifiers, a session ID known to an attacker remains the authenticated ID after the victim logs in. The attacker can reuse the fixed `PHPSESSID` to access the victim's `profile.php` or `student.php` data. The local PHP 7.4 reproduction accepted an attacker-selected 32-character SID, returned no replacement cookie after successful authentication, and served the authenticated profile when the same SID was replayed. |
