I just read through this which discusses using use Cwd;, however I didnt really see anything within the post that dealt with -T checks against the module. I just read through Ovid's writeup on web programming and so I am dutifully adding taint checking to my cgi scripts and in the process trying to go through to untaint them.

My burden at the moment is a script which calls $dir = `pwd`; I think this is something that you could find in a lot of code out there. After reading the post about use Cwd; I thought my issues were solved. However the following test code:

#!/usr/bin/perl -wT

use strict;
use Cwd;

my $dir = cwd();

print "$dir\n";

ends up still complaining with:

Insecure $ENV{PATH} while running with -T switch at /usr/lib/perl5/5.0
+0503/Cwd.pm line 82.

Do I need a more current revision of Cwd or is this not the way to find your cwd using -T?

humbly -c
