Description

This module attempts to gain root privileges on Juju agent systems running the juju-run agent utility. Juju agent systems running agent tools prior to version 1.25.12, 2.0.x before 2.0.4, and 2.1.x before 2.1.3, provide a UNIX domain socket to manage software ("units") without setting appropriate permissions, allowing unprivileged local users to execute arbitrary commands as root. This module has been tested successfully with Juju agent tools versions 1.18.4, 1.25.5 and 1.25.9 on Ubuntu 14.04.1 LTS x86 deployed by Juju 1.18.1-trusty-amd64 and 1.25.6-trusty-amd64 on Ubuntu 14.04.1 LTS x86_64.

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.
