Challenge Categories

The vulnerabilities found in the OWASP Juice Shop are categorized into several different classes. Most of them cover different risk or vulnerability types from well-known lists or documents, such as OWASP Top 10, OWASP ASVS, OWASP Automated Threat Handbook and OWASP API Security Top 10 or MITRE’s Common Weakness Enumeration.

Challenge Tags

Tags do not represent vulnerability categories but serve as additional meta information for challenges. They mark certain commonalities or special types of challenges - like those lacking seriousness or ones that probably need some scripting/automation etc.

Hacking Instructor Tutorials

Click on a link in the table below to launch a step-by-step tutorial for that particular challenge on our public https://demo.owasp-juice.shop instance. If you are entirely new to the Juice Shop, we recommend doing them in the listed order. With the (optional) Tutorial Mode you can even enforce that the 10 tutorial challenges have to be performed gradually in order to unlock the other 97 challenges.

Coding Challenges

For 27 challenges an additional coding challenge is available. In their “Find It” phase they teach spotting vulnerabilities in the actual codebase of the Juice Shop. In the “Fix It” phase the user then chooses the most appropriate fix from a list. Solve any of the hacking challenges below to enable a button on the Score Board that launches the corresponding coding challenge:

Mitigation Links

For many solved challenges links to mitigation techniques are presented on the Score Board by offering a link to a corresponding OWASP Cheat Sheet explaining how to avoid that kind of vulnerability in the first place. The following cheat sheets are referred to by OWASP Juice Shop as mitigation links:

• Authentication Cheat Sheet
• Authorization Cheat Sheet
• Choosing and Using Security Questions Cheat Sheet
• Credential Stuffing Prevention Cheat Sheet
• Cross-Site Request Forgery Prevention Cheat Sheet
• Cross Site Scripting Prevention Cheat Sheet
• Cryptographic Storage Cheat Sheet
• DOM based XSS Prevention Cheat Sheet
• Denial of Service Cheat Sheet
• Error Handling Cheat Sheet
• File Upload Cheat Sheet
• Forgot Password Cheat Sheet
• Injection Prevention Cheat Sheet
• Input Validation Cheat Sheet
• JSON Web Token for Java Cheat Sheet
• Key Management Cheat Sheet
• Logging Cheat Sheet
• Mass Assignment Cheat Sheet
• Multifactor Authentication Cheat Sheet
• REST Security Cheat Sheet
• SQL Injection Prevention Cheat Sheet
• Server Side Request Forgery Prevention Cheat Sheet
• Unvalidated Redirects and Forwards Cheat Sheet
• User Privacy Protection Cheat Sheet
• Vulnerability Disclosure Cheat Sheet
• Vulnerable Dependency Management Cheat Sheet
• Web Service Security Cheat Sheet
• XML External Entity Prevention Cheat Sheet
• XS Leaks Cheat Sheet
