I operate a small shared hosting area. While I notice that people are unable/struggle to exploit with PHP I have found a small minority of people using Perl in order to obtain server information.
So, to put it simply here is the question I would like to ask -
Is there a way to prevent Perl scripts from accessing certain system critical files such as named.conf /etc/passwd & others? Naturally suhosin/ suphp or php.ini does not protect against this when in a perl scenario.
