Subject: DOMDocument and <script> tag - XSS test
From: xwisdom@gmail.com (Raymond Irving)

--f46d04088c7598ea9c04c4eb3822
Content-Type: text/plain; charset=ISO-8859-1

Hello,

I'm having a problem with the DOM parser:

If I load the following using DOMDocument->loadHTML():

<script type="text/javascript"><!--
   var d="&quot;;alert('This is an XSS test'); //";
</script>

it will be converted to:

<script type="text/javascript"><!--
   var d="";alert('This is an XSS test'); //";
</script>

This is because parser is substituting '&quot;' for  '"'.

Is there a way to prevent this from happening?

Raymond
