Title: Just William's Amazon Webstore Closeup.PHP Image Parameter Cross-Site Scripting Vulnerability

Severity: MODERATE

Description:

Amazon Webstore is a project that is currently being developed at JustWilliam's. It is written in PHP and is designed to interface with Amazon's vast database of products.

Amazon Webstore is prone to a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input to the 'image' parameter of 'closeup.php'.

An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.

This issue reportedly affects Amazon Webstore version 04050100; other versions may also be vulnerable.

Affected Products:

  • Just William's Amazon Webstore 04050100
