Module Overview

Name: Allen-Bradley/Rockwell Automation EtherNet/IP CIP Commands
Module: auxiliary/admin/scada/multi_cip_command
Source code: modules/auxiliary/admin/scada/multi_cip_command.rb
Disclosure date: 2012-01-19
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 44818
List of CVEs: -

The EtherNet/IP CIP protocol allows a number of unauthenticated commands to a PLC which implements the protocol. This module implements the CPU STOP command, as well as the ability to crash the Ethernet card in an affected device. This module is based on the original 'ethernetip-multi.rb' Basecamp module from DigitalBond.

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
