CVE-2022-29881Network attack vector

Unauthenticated configuration disclosure via unprotected developer views

Published May 10, 2022 · Updated Dec 9, 2025

Missing authentication in the Siemens SICAM T web interface before 3.0 allows remote attackers to read internal configuration details. Certain internal developer views lack special access protection, so the interface serves their configuration content without validating a session. Network reachability to the management interface is the only reported gate, and the documented consequence is read-only disclosure rather than device reconfiguration or interruption.
