Deeper analysis

CVE-2025-29905 affects TeleControl Server Basic in all versions prior to V3.1.2.2. The flaw is an SQL injection reachable via the internally used RestoreFromBackup method, allowing an authenticated remote attacker to bypass authorization controls and interact directly with the application's database.

An attacker who can reach TCP port 8000 on a vulnerable system can leverage the injection to read from and write to the database and execute code under the NT AUTHORITY\NetworkService account. The CVSS 4.0 score of 8.7 reflects network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.

The Siemens advisory at cert-portal.siemens.com/productcert/html/ssa-443402.html addresses the issue and provides the fixed version V3.1.2.2.

EPSS for the CVE rose from a low starting value of 0.0008 to a peak of 0.0100, indicating that exploitation interest increased after disclosure.
