CVE-2025-32839: 
Telecontrol Server Basic vulnerability analysis and mitigation

A SQL injection vulnerability (CVE-2025-32839) was discovered in TeleControl Server Basic (All versions < V3.1.2.2). The vulnerability was disclosed on April 16, 2025, affecting the internally used 'GetGateways' method. This security flaw allows an authenticated remote attacker to bypass authorization controls and potentially execute code with 'NT AUTHORITY\NetworkService' permissions (Siemens Advisory).

The vulnerability is classified as an SQL injection (CWE-89) that affects the 'GetGateways' 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 (Siemens Advisory).

If exploited, 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. A successful attack requires the attacker to have access to port 8000 on a system where a vulnerable version of the affected application is running (Siemens Advisory, CISA 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).
