XSS PHP

Description

A Stored Cross-Site Scripting (XSS) vulnerability exists in SourceCodester Sales and Inventory System 1.0. The vulnerability is located in the update_details.php file. The application fails to sanitize the "website" parameter provided in a POST request. This allows authenticated attackers to inject arbitrary web script or HTML that is stored in the database and executed whenever the store details page is accessed.

Analysis

Stored cross-site scripting (XSS) in SourceCodester Sales and Inventory System 1.0 allows authenticated attackers to inject malicious scripts via the unvalidated website parameter in update_details.php, which are persisted in the database and executed whenever the store details page is accessed by any user. Publicly available exploit code exists, though the vulnerability requires prior authentication and affects primarily self-hosted instances of this open-source inventory management application.
