Code-Projects Concert Ticket Reservation System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the Concert Ticket Reservation System version 1.0. The issue resides in the login.php file, specifically within the Parameter Handler component. The vulnerability is triggered by manipulating the 'Email' parameter, allowing attackers to inject malicious SQL queries. This flaw 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 data access, data leakage, unauthorized data modification or deletion, and in some cases, executing commands on the server.

Reproduction

The vulnerability can be reproduced by sending a POST request to the 'process_login.php' endpoint with a crafted 'Email' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits are also advisable.
