CVE-2022-42733Network attack vector

Unauthenticated file disclosure via web service path

Published Nov 17, 2022 · Updated Apr 29, 2025

Improper file access in Siemens Healthineers syngo Dynamics before VA40G HF01 allows remote attackers to read server files. An application-server web-service operation accepts an attacker-controlled file path without enforcing read authorization, then retrieves any file readable by the website application-pool account. No authentication or user interaction is required, but the service is intended only for trusted nodes and the Internet-facing Web Portal is not affected.
