CVE-2025-30032
Telecontrol Server Basic vulnerability analysis and mitigation

Overview

A SQL injection vulnerability (CVE-2025-30032) was identified in TeleControl Server Basic (versions prior to V3.1.2.2). The vulnerability exists in the internally used 'UpdateDatabaseSettings' method and was discovered on April 16, 2025. The affected software is Siemens TeleControl Server Basic, which is used for remote monitoring and control of plants via WAN/LAN (Siemens Advisory).

Technical details

The vulnerability is classified as SQL Injection (CWE-89) with a CVSS v3.1 Base Score of 8.8 HIGH (Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and a CVSS v4.0 Base Score of 8.7 (Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N). The vulnerability specifically affects the 'UpdateDatabaseSettings' method in the application (Siemens Advisory).

Impact

If successfully exploited, this vulnerability allows an authenticated remote attacker to bypass authorization controls, read from and write to the application's database, and execute code with 'NT AUTHORITY\NetworkService' permissions. The attack requires the attacker to have access to port 8000 on a system where a vulnerable version of the application is running (Siemens Advisory).

Mitigation and workarounds

Siemens has released version V3.1.2.2 which fixes this vulnerability. As a workaround, organizations are advised to restrict access to port 8000 on affected systems to trusted IP addresses only. Siemens also recommends configuring the environment according to their operational guidelines for Industrial Security (Siemens Advisory).
