CVE-2023-30901Network attack vector

Authenticated action forgery via web interface CSRF

Published Jun 13, 2023 · Updated Dec 9, 2025

Cross-Site Request Forgery in Siemens SICAM P850 and P855 before V3.11 and SICAM T before V3.0 allows remote attackers to alter device state. The web interface accepts state-changing requests from a malicious site without verifying that the authenticated session intentionally initiated them. An authenticated victim must click the attacker-controlled link, after which arbitrary actions execute with the victim's device privileges; the documented impact is integrity loss without stated confidentiality or availability impact.
