CodeProjects Online Restaurant Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in CodeProjects Online Restaurant Management System version 1.0. The issue resides in the '/admin/category_update.php' file, where the 'id' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to gain unauthorized access to the database, leak sensitive information, alter or delete data, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, leakage of sensitive information, and could lead to a complete compromise of the system.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/admin/category_update.php' file with a crafted 'id' parameter. This parameter can be manipulated to include malicious SQL payloads that exploit the application's SQL query handling. The injection can be verified by using payloads that, for example, cause a time delay or trigger a SQL error, indicating successful exploitation.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to separate SQL code from user input, validate and filter input data, minimize database user permissions, and conduct regular security audits.
