The following courtesy of 'bitlance winter' adds an entirely new
dimension to the matter and also suggest some additional
peculiarities at play:

<a href='http://&quot;&gt;&lt;plaintext&gt;.e-gold.com&apos;>foo</a>

<a href='http://&quot;&gt;&lt;script&gt;alert()&lt;%
2Fscript&gt;.e-gold.com'>foo</a>

these will inject arbitrary html and script into the site in the
context of the 'intranet zone', which means one no longer needs
to go out and setup a site with the dns issue, all one needs to
do is locate a functioning site, include their code into a
suitable url, either direct the target via that or place an
iframe elsewhere pointing to it.

Because the wildcarding is a bit too wild.

For instance, "http://&money.e-gold.com/ " resolves.

And, "http://&money;G-Money&OGbabyOG.e-gold.com/"; resolves.

In e-gold's case, they actually take the url line and render
it variously in their dynamic html on their page.




Still unclear how or why this can be interpreted into the site
or through the browser.
