This is an example of the prevalence of cheap hosting and open web frameworks. Overconfidence by do-it-yourself website creators that think that they've got it good, but fail to take all of the proper measures to secure their sites.
Hmm, I wonder how secure my site is. It's basically set up by the Mac OS X Server wizard.
