Subject: Re: Attacking the local LAN via XSS

this is a very good point. :) cheers for that

then the problem is not actually sending a HTTP POST request but
getting the result from it or even modifying the headers. None of the
modern browsers allows you to read the iframe source. Well, actually
it is more likely to get thins working on IE6...

on the other hand, most devices have some sort of authentication
mechanism... most likely HTTP Basic Auth... that needs to go to the
headers of the request and it is not possible to perform it HTML forms
unless unless you are using the XmlHttpRequest object from JavaScript.

thx
