Published: 16 April 2025
Summary
CVE-2025-31349 is a high-severity SQL Injection (CWE-89) vulnerability in Siemens Telecontrol Server Basic. Its CVSS base score is 8.7 (High).
Operationally, ranked at the 23.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
Deeper analysis
A SQL injection vulnerability exists in Siemens TeleControl Server Basic versions prior to V3.1.2.2. The flaw resides in the internally used UpdateSmtpSettings method and is tracked as CWE-89. An authenticated remote attacker who can reach TCP port 8000 on the affected system can exploit it to bypass authorization, read from and write to the application database, and execute code under the NT AUTHORITY\NetworkService account. The issue carries a CVSS 4.0 score of 8.7.
Successful exploitation requires valid credentials and network access to the exposed port; no user interaction or special configuration beyond the default listening port is needed. An attacker can therefore obtain broad control over the application's data store and achieve code execution with service-level privileges on the host.
The EPSS score rose from a low of 0.0008 to a peak of 0.0100 after disclosure, indicating emerging exploitation interest. Siemens has published advisory SSA-443402 that addresses the affected product versions.
