| Título | OUSL-GROUP-BrinaryBrains School-Student-Management-System 1.0 Authentication Bypass |
|---|
| Descripción | The application supports automatic login restoration through a cookie named `school_auth`. The `MY_Controller` constructor unconditionally attempts to recover a user session from this cookie via `restore_auth_session_from_cookie()`. The cookie’s integrity is protected by an HMAC-SHA256 signature generated by the method `sign_auth_cookie()`:
```php
protected function sign_auth_cookie($role, $user_id)
{
return hash_hmac('sha256', strtolower($role) . ':' . (int) $user_id, (string) $this->config->item('encryption_key'));
}
``` |
