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.

Stability:

  • crash-service-restarts: Module may crash the service, but the service restarts.

Side Effects:

  • physical-effects: Module may produce physical effects (Examples: the device makes movement or flashes LEDs).

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/hardware/automotive/ecu_hard_reset

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/hardware/automotive/ecu_hard_reset
msf post(ecu_hard_reset) > show options
    ... show and set options ...
msf post(ecu_hard_reset) > set SESSION session-id
msf post(ecu_hard_reset) > 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/hardware/automotive/ecu_hard_reset")
  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 performs hard reset in the ECU Reset Service Identifier (0x11).

Verification Steps

Fire up virtual CAN bus:

  1. sudo modprobe can
  2. sudo modprobe vcan
  3. sudo ip link add dev vcan0 type vcan
  4. sudo ip link set up vcan0

Launch msf:

  1. Start msfconsole
  2. use auxiliary/server/local_hwbridge
  3. set uripath testbus
  4. run
  5. use auxiliary/client/hwbridge/connect
  6. set targeturi testbus

Options

ARBID CAN ID to perform ECU Hard Reset (Default: 0x7DF)

CANBUS CAN Bus to perform scan on, defaults to connected bus

Scenarios

Using UDS simulator for testing ECU hard reset:

msf5 auxiliary(client/hwbridge/connect) > run
[*] Running module against 127.0.0.1

[*] Attempting to connect to 127.0.0.1...
[*] Hardware bridge interface session 2 opened (127.0.0.1 -> 127.0.0.1) at 2019-09-11 04:59:40 -0700
[+] HWBridge session established
[*] HW Specialty: {"automotive"=>true}  Capabilities: {"can"=>true, "custom_methods"=>true}
[!] NOTICE:  You are about to leave the matrix.  All actions performed on this hardware bridge
[!]          could have real world consequences.  Use this module in a controlled testing
[!]          environment and with equipment you are authorized to perform testing on.
[*] Auxiliary module execution completed
msf5 auxiliary(client/hwbridge/connect) > sessions

msf5 auxiliary(client/hwbridge/connect) > sessions -i 1
[*] Starting interaction with 1...

hwbridge > run post/hardware/automotive/ecu_hard_reset CANBUS=vcan0

[*] Performing ECU Hard Reset...

You can use candump to verify the CAN messages being sent:

─$ candump vcan0          
  vcan0  7DF   [8]  02 11 01 00 00 00 00 00

UDS Server Output └─$ ./uds-server -v -V "PWN3D" vcan0 Using CAN interface vcan0 Fuzz level set to: 0 Pkt: 7DF#02 11 01 00 00 00 00 00 Unhandled mode/sid: ECU Reset
