Automated privilege escalation of the world's most popular Docker images

This repository contains the results of a Trickest workflow that performs a collection of multiple types of security checks and vulnerability tests on DockerHub's top 100 most downloaded images. The tests include (but are not limited to):

• Checking for the usage of outdated software with known exploits
• Searching for developer tools installed
• Getting the base OS
• cating the /etc/passwd and /etc/shadow in search for blank passwords
• Finding files owned by root user
• Searching for guid and suid executables
• Searching for hidden files, package names, world writable files and folders
• Enumerating password policies and SSL sertificates
• Enumeration of GTFOBins
• Scanning for open ports
• Add your own tests!

How it Works

A Trickest workflow collects a list of DockerHub's most used images and their tags. Then it uses a collection of custom scripts and a couple of open-source tools like trivy to get an overview of each image's security posture and overall attack surface.

• We start by enumerating a list of the most popular images from DockerHub - this step can be modified to pull images from other (potentially private) image repositories as well.
• Once collected, Trickest's Docker-in-Docker integration is used to pull all tags of each image.
• Then a series of tests are run on each image:
  • Trivy is used to find outdated software (thanks aquasecurity!)
    • 💡 Tip: CVEs repository is hyperlinked for CVEs that have POCs!
  • A few shell scripts are also included to carry out other tests and collect other data (Contributions are welcome!)
• In the end, each test's results are written to a simple report and pushed to this repository.
• As with most of our previous projects, this workflow is scheduled to run constantly and always have up-to-date results.
