Is the script internal to Cisco? I would love to do some internal testing in my lab on a few different versions before I send notifications to our clients that have the affected versions.<br>
<br>
In other words can I please have the script? :)<br>

I don't think that's the correct advisory. That's a DoS vulnerability from 2004.<br>
