Understanding exploit templates and mixins

Let's suppose that you have written an exploit code for a new zero-day vulnerability. Now, if you want to make it part of the Metasploit Framework, you need to ensure it is in a particular format. Fortunately, you just need to focus on the actual exploit code and then simply use a readily available template (provided by the Metasploit Framework) to insert it in the required format.

The exploit module skeleton is readily provided by the Metasploit Framework, as in the following code:

##
# This module requires Metasploit: http://metasploit.com/download

require 'msf/core'
class MetasploitModule < Msf::Exploit::Remote

super(update_info(info,
'Name' => '[Vendor] [Software] [Root Cause] [Vulnerability type]',
'Description' => %q{
