Eclipse GlassFish versions up to 7.0.16 are vulnerable to brute force attacks due to the lack of rate limiting on failed login attempts. Attackers can repeatedly submit authentication requests without restrictions, allowing them to guess credentials systematically. The absence of account lockout mechanisms or delay enforcement increases the risk of unauthorized access. This flaw stems from improper session handling in the authentication module, where failed attempts are not logged or throttled. The vulnerability is exploitable remotely without requiring elevated privileges.
