CVE-2025-32837
Published: 16 April 2025
Summary
CVE-2025-32837 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 12.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
Deeper analysis
A vulnerability has been identified in TeleControl Server Basic versions prior to V3.1.2.2 consisting of an SQL injection flaw in the internally used GetActiveConnectionVariables method. The affected component allows an authenticated remote attacker who can reach TCP port 8000 to bypass authorization controls, read from and write to the application's database, and execute code under the NT AUTHORITY\NetworkService account. The issue is tracked as CWE-89 and carries a CVSS 4.0 score of 8.7.
An attacker with valid credentials and network access to the exposed port can leverage the injection to escalate privileges within the database and obtain code execution on the underlying Windows host. Because the method is invoked internally, the attack does not require user interaction beyond initial authentication and can be performed entirely over the network.
The Siemens advisory SSA-443402 recommends upgrading to version 3.1.2.2 or later, which contains the fix for the SQL injection.
The EPSS score for this CVE rose from a low of 0.0004 to a peak of 0.0100 after disclosure, indicating emerging exploitation interest that warrants renewed attention.
