Description
Nefteprodukttekhnika BUK TS-G Gas Station Automation System 2.9.1 on Linux contains a SQL Injection vulnerability (CWE-89) in the system configuration module. A remote attacker can send specially crafted HTTP POST requests to the /php/request.php endpoint via the sql parameter in application/x-www-form-urlencoded data (e.g., action=do&sql=<query_here>&reload_driver=0) to execute arbitrary SQL commands and potentially achieve remote code execution.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
