Re: XSS Tunnelling White Paper and Tool

This is very cool. This is a perfect example of an alternate means to exploit lazy admins :)

Consider a small/medium managed hosting company with public support forums. The forums aren't high on anyone's list to secure because they've got better things to do. Mallory discovers some exploits in the forum (or just un-checked HTML in postings) and posts an XSS described in the whitepaper into the forums. Bob, the admin browses the forums, gets infected and then browses to the admin interface of one of his customer's boxes. Mallory now has control over the managed server.

Better yet, embedded in a message to an HTML email client (to one of those services that doesn't sanitize properly). The possibilities are endless...

Thanks for the brilliant XSS demo tool.
