Technical details

An authentication bypass vulnerability exists in the `sign_auth_cookie` function within `application/controllers/Login.php` (part of `MY_Controller`). The application uses a hardcoded encryption key ('Signetbd') in `application/config/config.php` to generate HMAC-SHA256 signatures for the `school_auth` cookie. Because the key is static and publicly known, a remote, unauthenticated attacker can forge a valid `school_auth` cookie for any role (e.g., admin, teacher) and user ID. When the server processes this forged cookie via `restore_auth_session_from_cookie()`, it validates the signature against the hardcoded key and establishes a valid session, granting the attacker full access to the impersonated account. As of the advisory date, no patch has been released by the vendor.
