Code-Projects Simple Shopping Cart SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Simple Shopping Cart version 1.0, specifically in the '/Customers/settings.php' file. The issue arises from inadequate validation of the 'user_id' parameter, which allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Customers/settings.php' with a crafted 'user_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.
