Deeper analysis

CVE-2025-30031 is an SQL injection vulnerability in Siemens TeleControl Server Basic versions prior to V3.1.2.2. The flaw exists in the internally used UpdateUsers method and stems from insufficient input sanitization, allowing improper database query construction.

An authenticated remote attacker with network access to TCP port 8000 on a host running the vulnerable application can exploit the issue to bypass authorization, read from or write to the application's database, and execute arbitrary code under the NT AUTHORITY\NetworkService account. The CVSS 4.0 score of 8.7 reflects network attack vector, low complexity, and high impact on confidentiality, integrity, and availability.

The Siemens security advisory SSA-443402, referenced at cert-portal.siemens.com/productcert/html/ssa-443402.html, addresses the vulnerability and provides remediation guidance for affected TeleControl Server Basic deployments.

EPSS for the CVE rose from a low baseline of 0.0008 to a peak of 0.0100, indicating emerging exploitation interest after disclosure.
