Snitz Forums 2000 Image Tag Cross-Agent Scripting Vulnerability

Snitz Forums 2000 is ASP-based web forum software. It runs on Microsoft Windows operating systems.

Snitz Forums 2000 allows users to include images in forum messages using image tags, with the following syntax:

[img]url of image[/img]

It is possible to inject arbitrary script code into forum messages via these image tags. Script code will be executed in the browser of the user viewing the forum message, in the context of the website running the vulnerable software. This may allow an attacker to steal cookie-based authentication credentials.
