Campcodes Online Food Ordering System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Campcodes Online Food Ordering System version 1.0. The issue resides in the file '/routers/router.php', where the 'username' 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, tamper with data, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, data modification or deletion, 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 '/routers/router.php' with the 'username' parameter crafted to include malicious SQL payloads. For example, injecting SQL that exploits time-based blind SQL injection techniques, such as using 'SLEEP' functions to create a delay, can demonstrate the vulnerability.

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 user input to ensure it meets expected formats, minimize database user permissions, and conduct regular security audits.
