Projectworlds Travel Management System SQL Injection Vulnerability in Enquiry.php

A critical SQL injection vulnerability has been identified in Projectworlds Travel Management System version 1.0. The issue resides in the file '/enquiry.php', where insufficient input validation of the 't2' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized access to database information, modification or deletion of data, and in some cases, execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/enquiry.php' with the 't2' parameter included. The request can be crafted to include a SQL injection payload, such as a time-based blind SQL injection that uses the 'SLEEP' function to demonstrate the injection's effectiveness. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to separate SQL code from user input, ensuring that injected data is not executed as part of a SQL command. Additionally, input validation and filtering should be applied to confirm that user input meets expected formats. Minimizing database user permissions and conducting regular security audits can further enhance the application's security.
