Campcodes Grocery Sales and Inventory System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Grocery Sales and Inventory System version 1.0. The issue arises in the file '/ajax.php?action=save_product', where insufficient validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions pose a serious threat to the overall security of the system and its data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/ajax.php?action=save_product' with a crafted 'id' 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

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.
