Name of the Vulnerable Software and Affected Versions TeleControl Server Basic versions prior to 3.1.2.2

Description The issue allows an authenticated remote attacker to bypass authorization controls, read from and write to the application's database, and execute code with "NT AUTHORITYNetworkService" permissions through SQL injection in the UnlockOpcSettings method. A successful attack requires access to port 8000 on a system where a vulnerable version of the application is executed.

Recommendations For versions prior to 3.1.2.2, update to version 3.1.2.2 or later to resolve the issue. As a temporary workaround, consider restricting access to port 8000 to minimize the risk of exploitation. Additionally, limiting the use of the UnlockOpcSettings method until a patch is applied can help mitigate the risk.
