CVE-2025-32837Network attack vector

Authenticated code execution via GetActiveConnectionVariables SQL injection

Published Apr 16, 2025 · Updated Apr 17, 2025

SQL injection in Siemens TeleControl Server Basic before 3.1.2.2 allows remote authenticated users to execute code through port 8000. Siemens identifies GetActiveConnectionVariables as the injection locus but does not disclose which input reaches an SQL statement or how it is neutralized. Successful exploitation requires authenticated port access and permits authorization bypass, database reads and writes, and code execution as NetworkService.
