CVE-2025-32863: 
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 'UnlockTraceLevelSettings' method. This could allow an authenticated remote attacker to bypass authorization controls, to read from and write to the application's database and execute code with "NT AUTHORITY\NetworkService" permissions. The vulnerability was discovered and disclosed on April 16, 2025 (Siemens Advisory, CISA Advisory).

The vulnerability is classified as SQL Injection (CWE-89) with a CVSS v3.1 base score of 8.8 (HIGH) and vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The CVSS v4.0 base score is 8.7 with 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. 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 (NVD, Siemens Advisory).

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 (CISA Advisory).

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