Pwning OWASP Juice Shop

About the Book

This is the official companion guide to the OWASP Juice Shop application. Being a web application with a vast number of intended security vulnerabilities, the OWASP Juice Shop is supposed to be the opposite of a best practice or template application for web developers: It is an awareness, training, demonstration and exercise tool for security risks in modern web applications. The OWASP Juice Shop is an open-source project hosted by the non-profit Open Web Application Security Project (OWASP) and is developed and maintained by volunteers.

The book is divided into three parts:

Part I - Hacking preparations

Part one helps you to get the application running and to set up optional hacking tools.

Part II - Challenge hunting

Part two gives an overview of the vulnerabilities found in the OWASP Juice Shop including hints how to find and exploit them in the application.

Part III - Getting involved

Part three shows up various ways to contribute to the OWASP Juice Shop open source project.
