I fail to see how it can be exploited?    My AV software will capture the
bad things, my firewall will block ALL types of traffic coming into my
machine by default.   All uncessary ports have been disbled from listening
and the only ones I have open are the ones I know I require.  I do not see
how one unfiltered URL data in a CFML page can exploit the machine?

Unfortunately, it isn't nonsense. The problem with this is that, if you do
allow any legitimate incoming traffic, and there's any chance that this
traffic can be exploited, and you don't limit outbound traffic, you can't
really get a handle on your machine's security. This won't be caught by the
"how safe is your machine" tools, either. All it takes is one unfiltered SQL
query using form or URL data in a CFML page (malformed data passed through
"legitimate channels").
