Executive Summary

This vulnerability is a stored Cross-Site Scripting (XSS) flaw in the Inventory Management System 1.0 by SourceCodester. It exists in the Product Management module where user input in the Product Name field is not properly sanitized before being stored or displayed. Attackers can inject malicious JavaScript into this field, which executes when other users view the Product Catalog page.

Detection Guidance

To detect this XSS vulnerability, inspect HTTP requests to /api/products_handler.php for unsanitized Product_Name parameters. Use browser developer tools to check if product names render unencoded JavaScript. Test by submitting a payload like <script>alert(1)</script> in the Product Name field and verify if it executes when viewing the Products page.

Impact Analysis

An attacker could steal session cookies or sensitive data from authenticated users viewing the Product Catalog page. This could lead to account takeover, unauthorized access to the system, or further exploitation of user privileges. The Products page is frequently accessed by staff and administrators, increasing the risk.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR and HIPAA requirements for data protection and confidentiality. Non-compliance may result in legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Apply htmlspecialchars() to all product fields before database storage. Implement strict server-side input validation to reject scripts or HTML tags. Set Content Security Policy headers to block inline scripts. Ensure DataTables output encoding is enabled to prevent script execution in rendered pages.
