The remote web server contains a script that is vulnerable to a Cross-Site Scripting (XSS) attack.
The remote host is using Brooky CubeCart, an online storefront application written in PHP. This version of CubeCart is vulnerable to multiple XSS Injection flaws. An attacker exploiting these flaws would need to be able to convince a user to browse to a malicious URI. Successful exploitation would result in code execution within the user's browser that could lead to theft of authentication materials.
Upgrade to version 3.0.4 or higher.
