Very interesting...

First thing, their Perlmonks link is also pointing to your tutorial. Someone has to get enough courange and tell the Commandos of the little slip ;-)).

In terms of security, abusing a CGI script is one sure way of hacking into a server. Check out this page, for example. I also have numerous links on my box to sites that discuss various exploits.. as far as I can tell cracking a server script (CGI, etc) is very much favoured by many hackers. Therefore, of course, DoD should get _absolutely_ concerned with their security as in this day and age, those kind of IT attacks could prove more damaging than any direct military action. Soon (and I don't even claim to be a visionary), the first thing a foe country would do prior to launching a 'physical' attack is hack opponent's servers in order to establish immediate strategic superiority and thereby assure seamless conquest.
