Shared Network Namespace
container-security-container-host-security-breakouts | Level: Easy | Total Lab Runs: 0 | Premium Lab |
There are multiple administrative tools available today which helps developers and operation teams in managing Docker hosts/swarms. Such
tools require high privileges to perform various operations (e.g.
starting a container with special capabilities, attaching to any container etc.). However, if they are not protected well, they can lead to compromise.
In this lab exercise, a machine on the network is running a Portainer instance on the localhost interface. The network namespace of the host machine is shared with a container that is running a web application. The web application is vulnerable to arbitrary file vulnerability and can be leveraged to interact with the network services running on the host machine.
Objective: Get access to Portainer UI, use it to get shell access on the host machine and retrieve the flag kept in the home directory of the root user on the host system!
You might need the following credentials for exploitation:
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a root terminal of a Kali instance
- Your Kali has an interface with IP address 192.X.Y.2. Run "ip addr" to know the values of X and Y.
- The target server should be located at the IP address 192.X.Y.3.
- Do not attack the gateway located at IP address 192.X.Y.1
- postgresql is not running by default so Metasploit may give you an error. Ignore it.
The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:
- Using automated scanners
- Using brute force attacks
- Denial of Service attacks
- Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
- Attacking the lab infrastructure
Users violating the above will be either temporarily or permanently banned from the website.
If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.
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 email@example.com 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.
