A session management vulnerability in AOS-8 allows previously authenticated users to retain network access after their accounts are administratively disabled. Existing sessions are not invalidated when credentials are revoked, enabling continued access until session expiration. An attacker with compromised credentials could exploit this behavior to maintain unauthorized access even after the account has been disabled.
