This module controls Sonic Pi via its local OSC server. The server runs on 127.0.0.1:4557 and receives OSC messages over UDP. Yes, this is RCE, but it's local. I suggest playing music. :-)

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.

Side Effects:

  • audio-effects: Module may cause a noise (Examples: audio output from the speakers or hardware beeps).
  • screen-effects: Module may show something on the screen (Example: a window pops up).

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/osx/manage/sonic_pi

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/osx/manage/sonic_pi
msf post(sonic_pi) > show options
    ... show and set options ...
msf post(sonic_pi) > set SESSION session-id
msf post(sonic_pi) > 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/osx/manage/sonic_pi")
  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.

Knowledge Base

Introduction

This module controls Sonic Pi via its local OSC server.

The server runs on 127.0.0.1:4557 and receives OSC messages over UDP.

Setup

I've supported only OS X. I had no luck running Sonic Pi on Windows, and I can't test Raspberry Pi at the moment.

brew cask install sonic-pi if you have Homebrew or download and install Sonic Pi from https://sonic-pi.net/#mac.

Actions

Name  Description
----  -----------
Run   Run Sonic Pi code
Stop  Stop all jobs

Options

OSC_HOST

This is the OSC server host, which is 127.0.0.1 by default.

OSC_PORT

This is the OSC server (UDP) port, which is 4557 by default.

START_SONIC_PI

Enable this to start Sonic Pi if it isn't running already. Note that this will start the GUI, which will be visible to the user.

FILE

This is the path to Sonic Pi code you want to run. It can be arbitrary Ruby.

SonicPiPath

This is the path to the Sonic Pi executable within its application bundle.

RubyPath

This is the path to a Ruby executable. Sonic Pi's vendored Ruby is the default.
