PHPGurukul Vehicle Parking Management System SQL Injection Vulnerability in reg-users.php

A critical SQL injection vulnerability has been identified in PHPGurukul Vehicle Parking Management System version 1.13. The issue resides in the admin/reg-users.php file, where the del parameter is manipulated to inject malicious SQL code. This exploitation occurs without proper input validation or sanitization, allowing attackers to interfere with SQL queries and execute unauthorized database operations. The vulnerability can be exploited remotely, and a public exploit is available.

Impact

Exploitation of this vulnerability allows attackers to gain unauthorized access to the application's database, potentially leading to data manipulation, unauthorized data access, and in some cases, full system control.

Reproduction

The vulnerability can be reproduced by sending a GET request to the admin/reg-users.php file with the del parameter. The injected payload should be crafted to exploit the SQL injection vulnerability, such as using a time-based blind SQL injection payload that leverages the RLIKE operator to test for SQL injection vulnerability by causing a delay in the response.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection vulnerabilities. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats, blocking malicious inputs. Finally, database user permissions should be minimized, ensuring that the database account used by the application has only the necessary privileges.
