Corrupting Source Image II
container-security-image-security-registry | Level: Easy | Total Lab Runs: 0 | Premium Lab |
The target docker server is running multiple containers. Some of the docker images used for these containers are stored on the unprotected private docker registry present on the same network. A watchtower instance deployed on the target server ensures that the latest image present in the private repository is used for the containers. A flag is kept in /share directory of the host machine which is mounted to one of the containers.
Objective: Leverage this arrangement to retrieve the flag from the container!
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a Ubuntu docker host terminal instance.
- The target docker server can be accessible on "targetserver" domain.
- The private registry can be accessed on "registry" domain on port 5000.

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 firstname.lastname@example.org 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.
