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 '/messageexec.php' file, where the 'name' parameter is manipulated to inject malicious SQL queries. This vulnerability allows attackers to gain unauthorized access to the database, modify or delete data, and access sensitive information. The vulnerability can be exploited remotely without any authentication.

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 'messageexec.php' with a crafted 'name' parameter that includes malicious SQL payloads. This injection takes advantage of the application's failure to properly validate or sanitize user input before it is used in SQL queries. The injection can be confirmed by using SQL injection testing tools, such as sqlmap, to extract database information or manipulate database contents.

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 user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can further enhance the application's security.
