Code-Projects Vehicle Showroom Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the Vehicle Showroom Management System version 1.0. The issue resides in the file '/util/PaymentStatusFunction.php', where the 'CUSTOMER_ID' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, with potential consequences including unauthorized database access, data manipulation, and disruption of service.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/util/PaymentStatusFunction.php' file with a crafted 'CUSTOMER_ID' parameter. Various payloads can be used to exploit the SQL injection, such as boolean-based blind injections, error-based injections, time-based blind injections, and UNION-based injections. These payloads can be automated using tools like sqlmap.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
