How do I use taint mode in my CGI/Perl script?
CGI/Perl Taint Mode FAQNotice that Perl 4 does not support the -T flag. Instead, version 4 of Perl distributions typically come with a separate executable altogether, "taintPerl". Windows NT and other non-UNIX Web servers may have trouble recognizing the first magical line of a Perl script. Executing the first line of a script with the command parameters in there is a UNIXism. Read the next section for issues involved in activating taint mode on WinNT, Win95/98, or Mac.

Related QuestionsOnce I activate taint mode is that it?
CGI/Perl Taint Mode FAQYou should test your script thoroughly to see if turning on taint mode stops anything from occuring. Usually the majority of your script will work fine. In fact if you are lucky, the whole program may work without any changes at all! Run-time checking means that taint mode Perl is constantly and vigilantly checking to see if the script is going to do anything unsafe with user input while the program runs. It does not stop checking after the script first compiles (compile-time checking).

CGI/Perl Taint Mode FAQWhen you make a system call to an external program or use its sister command, exec, taint mode also stops this from happening if the PATH has not been adjusted.

Being in "paranoid" mode, Perl stops the command from executing.
