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.
Conclusion & alert: CVE-2015-4051 is rated High Exploit Risk (87/100): CVSS Critical severity, with high exploitation likelihood (EPSS 5.73%, 92th percentile). Core evidence: 2 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +3.76% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
