|pam-disabled-bypass-authentication (10405)||High Risk|
PAM (Pluggable Authentication Module) could allow a remote attacker to bypass authentication and gain unauthorized access to the system, caused by a vulnerability in the authentication process. PAM validates disabled passwords as empty passwords. A remote attacker could exploit this vulnerability by authenticating using an unauthorized password to gain unauthorized access to the vulnerable system.
