CVE-2025-32830: 
Telecontrol Server Basic vulnerability analysis and mitigation

A vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2). The affected application is vulnerable to SQL injection through the internally used 'UnlockProject' method. This vulnerability, tracked as CVE-2025-32830, was disclosed on April 16, 2025. The 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) with a CVSS v3.1 base score of 8.8 (HIGH) and a CVSS v4.0 base score of 8.7. The vulnerability vector string for CVSS v3.1 is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, and for CVSS v4.0 is 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 exists in the 'UnlockProject' method and requires an authenticated remote attacker to access port 8000 on a system where a vulnerable version of the application is executed (CISA Advisory, Siemens Advisory).

A successful exploitation of 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. This could potentially lead to unauthorized access to sensitive data and system compromise (Siemens Advisory).

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