Lab Walkthrough Video:

A group of developers was migrating their monolithic applications to microservices architecture. Every developer had a low privileged account on the server. But as building docker images and running containers require additional privileges. Hence, the developers were added to the docker group. However, allowing a low privileged user to start a docker container is equivalent to providing root access on the host machine. And, the administrator was aware of this issue. Hence, he deployed a 3rd party docker firewall plugin which restricts the developers to a selective set of operations.  

In this lab exercise, the student user cannot run a container. However, the student user can list and exec into running containers.

Objective: Leverage a running container, escalate to the root user on the host machine and retrieve the flag!

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
