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.

Executive Summary

The vulnerability is a SQL Injection (CWE-89) found in the Nefteprodukttekhnika BUK TS-G Gas Station Automation System version 2.9.1 running on Linux. It exists in the system configuration module where a remote attacker can send specially crafted HTTP POST requests to the /php/request.php endpoint. By manipulating the sql parameter in the application/x-www-form-urlencoded data, the attacker can execute arbitrary SQL commands.

This can potentially allow the attacker to perform unauthorized actions on the database, including remote code execution.

Impact Analysis

This vulnerability can have severe impacts as it allows a remote attacker to execute arbitrary SQL commands without any authentication or user interaction.

  • Unauthorized access to sensitive data stored in the database.
  • Modification or deletion of critical data.
  • Potential remote code execution, which could lead to full system compromise.
  • Disruption of gas station automation system operations.
