CVE-2025-23365

Local privilege escalation via writable installation inputs

Published Jul 8, 2025 · Updated Jul 8, 2025

Privilege escalation in Siemens TIA Administrator before 3.0.6 allows local users to execute arbitrary code during installations. The application lets low-privileged users overwrite cache files and change the downloads path, then trigger an installation that runs attacker-controlled content. A local low-privileged account is required, and successful exploitation executes code with elevated privileges on the affected host.
