Codeproject Online Restaurant Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Codeproject's Online Restaurant Management System version 1.0. The issue resides in the '/reservation_save.php' file, where the 'first' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication or authorization requirements.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized database access, data manipulation, and in some cases, full system control or service disruption.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/reservation_save.php' file with a crafted 'first' 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

To address this vulnerability, 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 can also help enhance overall security.
