Descriptions
modules/rlm_unix/rlm_unix.c in FreeRADIUS before 2.2.0, when unix mode is enabled for user authentication, does not properly check the password expiration in /etc/shadow, which allows remote authenticated users to authenticate using an expired password.
modules/rlm_unix/rlm_unix.c en FreeRADIUS anterior a v2.2.0, cuando el modo unix está activado para la autenticación de usuarios, no valida adecuadamente la expiración de la contraseña en /etc/shadow, lo que permite a usuarios autenticados remotamente validarse mediante una contraseña caducada.
