Telecontrol Server Basic vulnerability analysis and mitigation

A vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2) tracked as CVE-2025-32846. The vulnerability was disclosed on April 16, 2025, and involves SQL injection through the internally used 'LockGeneralSettings' method. This vulnerability affects the TeleControl Server Basic application, which allows remote monitoring and control of plants via WAN/LAN (Siemens Advisory).

The vulnerability is classified as an SQL injection (CWE-89) that affects the 'LockGeneralSettings' method in TeleControl Server Basic. It has received a CVSS v3.1 base score of 8.8 (HIGH) with the vector string 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 with the vector string 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 requires network access to port 8000 on the affected system (Siemens Advisory).

If successfully 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. The impact spans across confidentiality, integrity, and availability of the system (Siemens Advisory).

Siemens has released version V3.1.2.2 which addresses 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).
