CVE-2025-32838: 
Telecontrol Server Basic vulnerability analysis and mitigation

A SQL injection vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2) through the internally used 'ImportConnectionVariables' method. The vulnerability was disclosed on April 16, 2025, and affects the TeleControl Server Basic application, which is used for remote monitoring and control of plants via WAN/LAN (Siemens Advisory).

The vulnerability is classified as a SQL injection (CWE-89) that exists in the 'ImportConnectionVariables' method. It has received a CVSS v3.1 Base Score of 8.8 (HIGH) with vector 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 (HIGH) with 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 (NVD).

If exploited, this vulnerability could allow 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. A successful attack requires the attacker to be able to access port 8000 on a system where a vulnerable version of the affected application is executed (Siemens Advisory).

Siemens has released version V3.1.2.2 which fixes this vulnerability. Users are recommended to update to this version. As a workaround, Siemens recommends restricting access to port 8000 on the affected systems to trusted IP addresses only (Siemens Advisory).
