DescriptionCVE.org

A vulnerability was detected in code-projects Online Shoe Store 1.0. This affects an unknown part of the file /admin/admin_feature.php of the component Add Product Page. The manipulation of the argument product_name results in cross site scripting. The attack may be launched remotely. The exploit is now public and may be used.

AnalysisAI

Stored cross-site scripting (XSS) in code-projects Online Shoe Store 1.0 allows authenticated administrators to inject malicious scripts via the product_name parameter in the Add Product Page (/admin/admin_feature.php), which execute in the context of other users' browsers. The vulnerability requires high-privilege administrative access and user interaction (clicking a malicious link), limiting real-world impact, but publicly available exploit code exists.

Technical ContextAI

This is a CWE-79 (Improper Neutralization of Input During Web Page Generation) vulnerability in a PHP-based e-commerce application. The Add Product Page endpoint fails to sanitize or encode user input from the product_name parameter before storing it in a backend system or reflecting it in HTML responses. When an administrator submits a crafted product name containing JavaScript (e.g., <script>alert('XSS')</script>), the application processes and renders this payload without validation, allowing arbitrary script execution within the victim's browser session. The vulnerability manifests as stored XSS if the payload is persisted in a database, or reflected XSS if echoed immediately in responses.

RemediationAI

Apply input validation and output encoding to the product_name parameter in /admin/admin_feature.php. Implement server-side sanitization using a whitelist approach (allow only alphanumeric characters, spaces, and safe punctuation) or use a dedicated XSS filtering library. Additionally, apply HTML entity encoding (e.g., htmlspecialchars() in PHP) when displaying product names in web contexts. Check the vendor's repository at https://github.com/Jacky159/Pub_0323/issues/1 for a patched version. If no official patch is available, restrict administrative access to trusted users only and conduct a security code review of other user input handling in the application.
