Php-nuke was the hacking testing ground. Nuke was atrocious for exploitation.

I was thinking about php-nuke I while back and it's terrible security rep. I figured it was just the regular PHP foot guns of the era, but I took a look at the code recently and boy howdy that was some truly atrocious code. I'm not security person (although perhaps security minded) and I found a million problems after a cursory glance.
