CVE-2025-32858: 
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 'UpdateWebServerGatewaySettings' method. This vulnerability, tracked as CVE-2025-32858, was disclosed on April 16, 2025. The 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 (Siemens Advisory, NVD).

The vulnerability is classified as an 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 exists in the application's handling of SQL queries through the 'UpdateWebServerGatewaySettings' method, which fails to properly sanitize user input (CISA Advisory).

Successful exploitation of this vulnerability could allow an authenticated 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).

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).
