Description |
|
|
Se ha descubierto una vulnerabilidad en mod-auth-shadow, un módulo de Apache que permite autenticar a los usuarios con las contraseñas shadow del sistema. mod-auth-shadow no comprueba los campos de caducidad en /etc/shadow . Por tanto, una cuenta caducada podría usarse para validar correctamente contra este módulo. Nótese que, si bien sólo Debian ha emitido un aviso al respecto, esta vulneabilidad afecta a cualquier distribución que incluya una versión vulnerable del paquete mod-auth-shadow. |
