Multithreaded MSF exploitation with ICMP verification

This recipe will demonstrate how to use bash to exploit a single vulnerability across multiple systems and use ICMP traffic to validate the successful exploitation of each. This technique requires little overhead and can easily be used to gather a list of exploitable systems.

Getting ready

To use the script demonstrated in this recipe, you will need to have access to multiple systems that each have the same vulnerability that can be exploited with Metasploit. In the example provided, a VM running a vulnerable version of Windows XP was copied to generate three instances of the MS08-067 vulnerability. For more information on setting up a Windows system, please refer to the Installing Windows Server recipe in Chapter 1, Getting Started, of this book. Additionally, this section will require a script to be written to the filesystem by using a text editor such as VIM or Nano. For more information on writing scripts, please refer to the Using...
