CVE-2025-32831
Published: 16 April 2025
Summary
CVE-2025-32831 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 UpdateProjectUserRights method. The affected component is the TeleControl Server Basic application, which listens on TCP port 8000 and is susceptible to manipulation of database queries through this method. The issue is tracked as CWE-89 and carries a CVSS 4.0 score of 8.7 reflecting network-accessible attack vectors with low complexity and low privileges required.
An authenticated remote attacker who can reach port 8000 on a system running a vulnerable instance can exploit the flaw to bypass authorization controls, read from and write to the application's database, and execute code under the NT AUTHORITY\NetworkService account. Successful exploitation therefore grants the attacker broad control over project user rights and underlying data without needing additional user interaction.
The Siemens advisory at https://cert-portal.siemens.com/productcert/html/ssa-443402.html addresses the issue and is the primary source for official mitigation guidance.
EPSS for the CVE rose from a low starting value of 0.0004 to a peak of 0.0100, indicating that exploitation interest emerged after disclosure and that the vulnerability warrants renewed attention.
