CVE-2024-35783Network attack vector

Administrative command execution via elevated database server

Published Sep 10, 2024 · Updated Jan 14, 2025

OS command execution in Siemens SIMATIC SCADA and PCS 7 products allows remote authenticated users to run commands as administrators. The products run their database server with elevated privileges, causing authenticated database command execution to cross into the operating system with administrative rights. High-privilege authentication is required, and successful exploitation grants arbitrary command execution with access to system data and services.
