Code-Projects Online Hotel Reservation System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Online Hotel Reservation System. The issue resides in the '/reservation/demo.php' file, where the 'start' parameter is manipulated to inject malicious SQL queries. This vulnerability allows remote attackers to gain unauthorized access to the database, modify or delete data, and access sensitive information. The vulnerability arises from inadequate input validation, enabling attackers to manipulate SQL queries and execute unauthorized operations.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of database contents, and access to sensitive information. Such actions could disrupt services and compromise overall system security.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/reservation/demo.php' with a crafted 'start' 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, validate and filter user input, minimize database user permissions, and conduct regular security audits.
