Descriptions
Yubico PAM Module before 2.10 performed user authentication when 'use_first_pass' PAM configuration option was not used and the module was configured as 'sufficient' in the PAM configuration. A remote attacker could use this flaw to circumvent common authentication process and obtain access to the account in question by providing a NULL value (pressing Ctrl-D keyboard sequence) as the password string.
El módulo PAM de Yubico versiones anteriores a 2.10, realizó la autenticación del usuario cuando no se utilizó la opción de configuración PAM "use_first_pass" y el módulo fue configurado como "sufficient" en la configuración PAM. Un atacante remoto podría usar este fallo para omitir el proceso de autenticación común y conseguir acceso a la cuenta en cuestión al proporcionar un valor NULL (presionando la secuencia de teclado Ctrl-D) como la cadena de contraseña.
