I believe the article that merlyn is trying to remember appeared in the Summer 1998 issue of The Perl Journal. It was called Safely Empowering Your CGI Scripts but you'll need to be a subscriber to view it.

Subscriptions cost $18/year and can be obtained online, which isn't too bad, considering that many other journals want a lot more money. There is, apparently some risk that the magazine is on the rocks (see TPJ future in question), but subscriptions allow immediate access to their online archives). Given that $18 is less than half the price of many tech books, it's cheap access to a lot of useful and extremely educational material.

If you'd rather not risk the subscription, I notice that Mr. Stein has a package that may help available on his web site; here's the direct link.
