| Titel | xxyopen novel-plus 5.1.3 Improper Restriction of Excessive Authentication Attempts |
|---|
| Beschreibung | The ajaxLogin method in the authentication module is vulnerable to a Captcha Replay Attack. The application correctly validates the user-submitted captcha against the one stored in the session but fails to invalidate or remove the captcha after its first use. This allows an attacker to reuse a single valid captcha indefinitely to perform automated brute-force or dictionary attacks against user passwords, completely bypassing the anti-automation security control. |
