Adds mixin to support resolving IPs across different session types

[cgranleese-r7]

This PR builds on a previous PR, specifically this comment thread.

This new mixin allows for DNS resolution for modules with multiple session types. E.g. modules/post/windows/gather/enum_computers.rb supports multiple sessions:

'SessionTypes' => %w[meterpreter powershell shell]

However the resolution across these session requires different logic. Meterpreter will now make use of the new Meterpreter API changes that will NEED to be landed before this PR can land.

metasploit-payloads PR - rapid7/metasploit-payloads#681
metasploit-framework PR - #18499

The mixin will check if we have a Meterpreter session with access to the net library and use the new Meterpreter API if so, otherwise fallback to nslookup if not.

Note

A rescue was added to the enum_computers module to allow for instances when the DNS isn't able to be resolved via the meterpreter API. This is due to inconsistent resolving methods in the runtime languages.

With no errors

With every entry returning an error

Mixed results

Verification

List the steps needed to make sure this thing works

• Start msfconsole
• use post/windows/gather/enum_computers.rb
• Target a machine with multiple computers available
• Get a Meterpreter session
• Verify the module now list all expected computers as part of that domain
  Example:

List of identified Hosts.
=========================

 Domain  Hostname  IPs
 ------  --------  ---
 VB      DC1       192.168.175.201, 192.168.175.200, 192.168.175.135

We'll need to make sure this works with ipv6

Will attic for now until we can pick this up again in the new year when we've got the other priorities out for this year 👍

Thanks for your contribution to Metasploit Framework! We've looked at this pull request, and we agree that it seems like a good addition to Metasploit, but it looks like it is not quite ready to land. We've labeled it attic and closed it for now.

What does this generally mean? It could be one or more of several things:

• It doesn't look like there has been any activity on this pull request in a while
• We may not have the proper access or equipment to test this pull request, or the contributor doesn't have time to work on it right now.
• Sometimes the implementation isn't quite right and a different approach is necessary.

We would love to land this pull request when it's ready. If you have a chance to address all comments, we would be happy to reopen and discuss how to merge this!

We'll want to handle the scenario of nslookup not being present; we can likely fall back to checking other binaries for unix environents, i.e.

$ host google.com
google.com has address 172.253.122.139
...  etc ...

Could we add automated tests for this: https://github.com/rapid7/metasploit-framework/tree/157763b2afa7ac990bc5a4e9a1bd1cfc25cdd58c/test/modules/post/test

So we can see if this functionality works across the board for our sessions

Let's add it to the recent test infra you wired up too, i.e. non-meterpreter shells: https://github.com/rapid7/metasploit-framework/pull/19413/files#diff-dfa8c541f020ceb4c845b17cffcac5b7e331498e527254f0b60b1bb4ba1c39b8
