Overview

This is a sample hardware bridge that demonstrates how to connect the HWBridge API to metasploit. It demonstrates some bare minimum capabilities to report back to the hardware connector and establish a hwbridge session. This module provides an example on how to connect any hardware component to Metasploit. It is also a fully functional interface to SocketCAN and will work to create an automotive HW Bridge.

Setup a Test

To experimient with using Metasploit to send automtovie CAN bus packets you can use the SocketCAN capabilities of Linux to create a virtual CAN device. NOTE: If you have a supported CAN sniffer you could also use a real can device.

In order for the local_hwbridge to inteface with SocketCAN you will need:

  • can-utils

Once those are installed you can setup a virtual CAN inteface using:

sudo modprobe can
sudo modprobe vcan
sudo ip link add dev vcan0 type vcan
sudo ip link set up vcan0

Once that is setup you can simply launch the module and it should auto detect any CAN intefaces you have active on the system.

msf > use auxiliary/server/local_hwbridge 
msf auxiliary(local_hwbridge) > run
[*] Auxiliary module execution completed

[*] Using URL: http://0.0.0.0:8080/xaUKu68Va
[*] Local IP: http://10.1.10.21:8080/xaUKu68Va
[*] Server started.

By default it will create a random URI, in this case it's xaUKu68Va.

Connecting to the HWBridge

You will need to use the auxiliary/client/hwbridge/connect to connect to the local_hwbridge. You can either use the same machine or another machine to connect to your local_hwbridge. Just make sure the TARGETURI matches the randomly generated URI

set TARGETURI xaUKu68Va

Then simply type run and you should connect to the HW bridge and a hwbridge session should be established. You can switch to the hwbridge session to interact with this module.

See the documentation for auxiliary/client/hwbridge/connect for more information on the hwbridge sessions.
