Exploit públicoDisponiblePublicado en Exploit-DB
Apache en Red Hat Linux con la directiva UserDir habilitada genera códigos de error distintos cuando un nombre de usuario existe pero no hay un directorio public_html, y cuando el nombre de usuario no existe, lo que podría permitir a atacantes remotos determinar nombres de usuario válidos en el servidor.
