Campcodes Online Shopping System SQL Injection Vulnerability in product.php

A SQL injection vulnerability has been identified in Campcodes Online Shopping System version 1.0, specifically within the product.php file. The issue arises from inadequate validation of user input in the 'p' parameter, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized access to the database, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access, modify, or delete database information. Additionally, it could lead to unauthorized execution of administrative operations on the database, and in some cases, allow for execution of commands on the server operating system.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to product.php with a manipulated 'p' parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities. The injection can be verified by using payloads that, for example, extract database information or bypass application logic.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure user input conforms to expected formats. Additionally, database user permissions should be minimized to the least privilege necessary.
