CVE-2025-32865: 
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 'CreateLog' 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. 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 on (NVD, Siemens Advisory).

The vulnerability is classified as an SQL Injection (CWE-89) issue. It has been assigned 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. A CVSS v4.0 base score of 8.7 has also been calculated 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 (CISA Advisory, Siemens Advisory).

Successful exploitation of this vulnerability could allow an attacker to read and write to the application's database, cause a denial-of-service condition, and execute code with NT AUTHORITY\NetworkService permissions. The attacker could potentially bypass authorization controls and gain unauthorized access to sensitive data (CISA Advisory).

Siemens has released version V3.1.2.2 which fixes this vulnerability. As a workaround, organizations should 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).
