Introduction

LXC is the well-known and heavily tested low-level Linux container runtime. It is in active development since 2008 and has proven itself in critical production environments world-wide. LXD is a next generation system container manager. that offers a user experience similar to virtual machines but using Linux containers instead.

The LXC/LXD groups are used to allow users to create and manage Linux containers. These can be exploited by creating a root-level privilege container from the current file system and interacting with it, executing /bin/sh and therefore starting a root shell.
