Deeper analysis
CVE-2025-32834 is an SQL injection vulnerability in Siemens TeleControl Server Basic versions prior to V3.1.2.2. The flaw exists in the internally used UpdateConnectionVariablesWithImport method and stems from insufficient input sanitization when handling database operations, as indicated by its CWE-89 classification.
An authenticated remote attacker who can reach TCP port 8000 on a system running the affected application can exploit the issue to bypass authorization controls, read from and 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 the combination of network attack vector, low complexity, and high impact on confidentiality, integrity, and availability without requiring user interaction.
The Siemens advisory at https://cert-portal.siemens.com/productcert/html/ssa-443402.html recommends upgrading to version V3.1.2.2 or later to address the vulnerability.
The EPSS score rose from a low of 0.0004 to a peak of 0.0100, indicating emerging exploitation interest after disclosure that warrants renewed attention.
