Descriptions

The "%xx" URL decoding function in Squid 2.5STABLE4 and earlier allows remote attackers to bypass url_regex ACLs via a URL with a NULL ("%00") character, which causes Squid to use only a portion of the requested URL when comparing it against the access control lists.

La función de decodificación de URL "%xx" en Squid 2.5STABLE4 y anteriores permite a atacantes remotos saltarse las listas de control de acceso (ACL) url_regex mediante una URL con un carácter nulo ("%00"), lo que hace que Squid use sólo un parte de la URL solicitada para compararla con la lista de control de acceso.
