Level:

Medium / Hard

Categories:

Docker, docker escape

Source handout:

No

Note

Manager/instance handler is not reliable, it was made in one afternoon and is not tested properly. But it works.

Inception

Inception is inspired by the movie Inception. You are inside a docker, inside a docker, inside a docker. You need to escape the current docker and get the flag.txt on the "system" (First docker level) (But actually second level if you count CTF manager (docker in a docker in a docker)).

Starting

1. Change flag in docker-compose.yaml.
2. Run docker-compose up --build -d in the root directory.
3. Visit localhost:5000 in your browser.
4. Enter nick name and connect to your instance.
