I was certainly delighted to read the article. Often, I find a lot of interesting stuff at www.securityfocus.com.
It surprises how easy it is to fool HTML aware sites that lack proper protection/filtering mechanisms. I'm wondering, also, if perlmonks.com is 100% secure from those types of attacks. Let me test it right here by including
<LINK REL=STYLESHEET TYPE="text/javascript" SRC=""> tag inside my post:
<LINK REL=STYLESHEET TYPE="text/javascript" SRC="">
I'm sure however this wouldn't work, since these posts are filtered and anything other than a set of accepted tags (such as readmore and common bracketed tags) is tossed away.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
