CVE-2022-42894Network attack vector

NTLM credential disclosure via unauthenticated SSRF

Published Nov 17, 2022 · Updated Apr 30, 2025

Server-side request forgery in a syngo Dynamics web service before VA40G HF01 allows remote attackers to leak NTLM credentials. Siemens Healthineers has not disclosed the affected service or operation, the request parameter involved, or the validation error that permits the server-side request. No authentication or user interaction is required, but the web services are intended for trusted nodes rather than Internet exposure; exploitation can expose NTLM credentials or enumerate local services.
