ECS: Process Injection

cloud-services-amazon-ecs | Level: Easy  | Total Lab Runs: 0 | Premium Lab

Lab Scoreboard

On AWS, ECS is a container orchestration service that allows us to deploy, manage, and scale containerized applications.

Containers running with additional privileges and volume mounts can pose a huge risk, as breaking out of an ECS container can provide access to an EC2 host. Once the attackers are inside the EC2 Host, further attacks can be performed on other resources based on the instance role/profile configuration.

In this lab exercise, you are provided with the root user of a container running in privileged mode.

Objective:  Break out of the container by leveraging the additional capabilities provided to the container and retrieve the flag stored in the tmp directory of the host system!

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.
