Schneider Modicon Remote START/STOP Command



The Schneider Modicon with Unity series of PLCs use Modbus function code 90 (0x5a) to perform administrative commands without authentication. This module allows a remote user to change the state of the PLC between STOP and RUN, allowing an attacker to end process control by the PLC. This module is based on the original 'modiconstop.rb' Basecamp module from DigitalBond.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/admin/scada/modicon_command
msf auxiliary(modicon_command) > show actions
msf auxiliary(modicon_command) > set ACTION < action-name >
msf auxiliary(modicon_command) > show options
    ...show and set options...
msf auxiliary(modicon_command) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
