Descriptions

Beckhoff IPC Diagnostics before 1.8 does not properly restrict access to functions in /config, which allows remote attackers to cause a denial of service (reboot or shutdown), create arbitrary users, or possibly have unspecified other impact via a crafted request, as demonstrated by a beckhoff.com:service:cxconfig:1#Write SOAP action to /upnpisapi.

Beckhoff IPC Diagnostics anterior a 1.8 no restringe correctamente el acceso a funciones en /config, lo que permite a atacantes remotos causar una denegación de servicio (reinicio o cierre), crear usuarios arbitrarios o posiblemente tener otro impacto no especificado a través de una solicitud manipulada, tal y como fue demostrado por una acción SOAP beckhoff.com:service:cxconfig:1#Write en /upnpisapi.

Beckhoff IPC Diagnostics versions prior to 1.8 suffer from an authentication bypass vulnerability.
