CVE-2015-4051
First published: Mon Jun 08 2015(Updated: )
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.
