Code-Projects Online Ordering System SQL Injection Vulnerability in User Deletion Function

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Online Ordering System. The issue resides in the admin/delete_user.php file, where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability 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, which could lead to unauthorized database access, manipulation or deletion of data, and access to sensitive information.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the admin/delete_user.php file with a payload that exploits the SQL injection flaw in the 'id' parameter. 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.
