CVE-2022-29883Network attack vector

Unauthenticated log deletion via unprotected web pages

Published May 10, 2022 · Updated Dec 9, 2025

Improper authentication in Siemens SICAM T before 3.0 allows remote attackers to delete device log files through the web interface. Certain web-interface pages expose log-deletion functions without enforcing authentication before the operation is accepted. Network reachability to the device is sufficient; the demonstrated consequence is integrity loss limited to stored logs.
