CVE-2023-1731Network attack vector

Authenticated command execution via configuration upload

Published Apr 24, 2023 · Updated Feb 4, 2025

Command injection in Meinberg LTOS before 7.06.013 allows remote authenticated users to execute arbitrary commands through configuration upload. The configuration-file upload handler fails to validate attacker-controlled input before processing it, exposing a command-execution path. Exploitation requires a high-privilege account on the appliance, and successful commands can compromise the LTOS host.
