CVE-2025-31349Network attack vector

Authenticated code execution via unvalidated SMTP settings string

Published Apr 16, 2025 · Updated Apr 16, 2025

SQL injection in Siemens TeleControl Server Basic before 3.1.2.2 allows remote authenticated users to execute code through port 8000. The UpdateSmtpSettings method uses a user-supplied string to construct SQL queries without proper validation. Access to the authenticated service permits database reads and writes, authorization bypass, and OS-shell execution as NT AUTHORITY\NetworkService.
