CVE-2022-40176Network attack vector

Root command execution via unvalidated restore filenames

Published Oct 11, 2022 · Updated Aug 3, 2024

OS command injection in Siemens Desigo PXM and PXG devices allows remote authenticated users to execute root commands during package restore. The restore handler passes unvalidated filenames from an imported package into an operating-system command that runs with root privileges. A low-privileged account and user interaction to restore a crafted package are required, after which the device is fully compromised.
