PHPGurukul Vehicle Parking Management System SQL Injection Vulnerability in Profile Management

A critical SQL injection vulnerability has been identified in PHPGurukul Vehicle Parking Management System version 1.13. The issue resides in the '/users/profile.php' file, where the 'firstname' parameter can be 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 there are indications that other parameters may also be susceptible.

Impact

Exploitation of this vulnerability allows attackers to inject malicious SQL queries, potentially leading to unauthorized database access, data manipulation or deletion, and exposure of sensitive information. Such actions could disrupt normal system operations and cause significant harm to the application's data integrity and security.

Reproduction

To reproduce this vulnerability, send a POST request to '/vpms/users/profile.php' with the 'firstname' parameter included in the multipart form data. Inject a payload that exploits the SQL injection vulnerability, such as a time-based blind injection payload that uses a SQL 'SLEEP' function to demonstrate the injection's effectiveness. The request should also include valid data for the other required parameters, such as 'lastname', 'mobilenumber', 'email', and 'regdate'.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection vulnerabilities. Additionally, implement thorough input validation and filtering to ensure that user input meets expected formats and does not contain malicious content. Finally, restrict database user permissions to the minimum necessary for application functionality, avoiding the use of accounts with high-level privileges.
