Challenge
Exploiting a simple command injection vulnerability
In this challenge, you will interface with a web API and exploit a simple command injection vulnerability. You will execute commands on a remote system via the web API.
-
Challenge
Bypassing a command injection blocklist
In this challenge, you will encounter a naive blocklist which will prevent you from using the simple command injection approach taken in the previous challenge. However, you will learn that there are a number of different ways to achieve the same command injection result which can be used to bypass a naive blocklist. Furthermore, you will learn how to execute commands with spaces, even when spaces are not directly permitted as an input.
-
Challenge
Executing arbitrary commands
In this challenge, you will encounter a more restrictive blocklist which will prevent you from using the simple command injection approach taken in the previous challenges. You will learn additional techniques and approaches to bypassing blocklists and ultimately executing arbitrary commands on the remote system.

The Last Challenge
Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
