Code-Projects Product Inventory System SQL Injection Vulnerability in Edit Product Admin Page

A critical SQL injection vulnerability has been identified in Code-Projects Product Inventory System version 1.0. The issue resides in the admin/edit_product.php file, where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely but requires authentication to access the affected page.

Impact

Exploitation of this vulnerability allows attackers to inject SQL queries that could be executed by the database. This could lead to unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, log into the application as an admin user. Once authenticated, navigate to the admin/edit_product.php page. The vulnerability can be exploited by manipulating the 'id' parameter in the URL to inject SQL payloads. This can be done using a boolean-based blind SQL injection technique, or a time-based blind SQL injection technique, where the injected SQL query is crafted to either return a true/false response or to delay the response by a specified amount of time, indicating successful injection.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection vulnerabilities. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
