Container Platforms

This module looks for container platforms running on the target and then lists any currently running containers for each platform found. The currently supported container platforms are:

  1. Docker

  2. LXC

  3. RKT

Verification Steps

  1. Start msfconsole

  2. Get a session via exploit of your choice

  3. Load the module use post/linux/gather/enum_containers

  4. Set the session set session 1

  5. run the module run

  6. You should get feedback if any container platforms are runnable by the current user and if there are any active containers running on them

Options

SESSION

Which session to use, which can be viewed with sessions -l

CMD

Optional shell command to run on each running container

Scenarios

Scenario 1: Docker is installed with 4 running containers

msf5 post(linux/gather/enum_containers) > set session 4
session => 4
msf5 post(linux/gather/enum_containers) > run
