CVE-2023-30897

Local privilege escalation via installation-folder permissions

Published Jun 13, 2023 · Updated Jan 3, 2025

Incorrect installation-folder permissions in Siemens SIMATIC WinCC before 7.5.2.13 allow local users to execute code with elevated privileges. When a non-default installation path is chosen, the installer fails to assign proper access rights to that folder, allowing unprivileged code to be placed or modified there. Exploitation requires authenticated local access and the non-default path configuration; successful code injection escalates privileges on the host.
