Descriptions

The checkHTTPpassword function in http.c in ntop 3.3.10 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an Authorization HTTP header that lacks a : (colon) character in the base64-decoded string.

La función checkHTTPpassword en http.c en ntop 3.3.10 y versiones anteriores permite a atacantes remotos provocar una denegación de servicio (referencia a un puntero nulo y caída del demonio) mediante una cabecera HTTP Authorization que carece de un caracter : (dos puntos) en la cadena base64-decoded.

ntop versions 3.3.10 and below suffer from a basic authentication null pointer denial of service vulnerability.
