Overview What You Will Learn Curriculum Instructor

Lab Description

In this lab, you will step into the role of a security analyst tasked with performing a source code review of OWASP Juice Shop—a purposely vulnerable web application used for security training. The focus of your analysis is on how the application handles sensitive data, such as passwords and credit card information.

You will explore the GitHub repository of Juice Shop to identify insecure coding patterns, including unsanitized SQL queries that expose the application to SQL injection attacks. A particular focus will be given to how the application uses the Finale package to process and expose data, and whether this integration introduces any security concerns. As part of your investigation, you will simulate SQL injection attacks to validate your findings and assess the actual impact of these flaws. Furthermore, you will analyze how credit card details and authentication credentials are managed and stored, checking for improper handling like plaintext storage or inadequate hashing algorithms.

Your final task is to document the identified vulnerabilities and recommend improvements, such as the use of prepared statements, secure cryptographic storage mechanisms, and data validation best practices. This lab will help reinforce the importance of secure coding techniques in safeguarding user data and maintaining application integrity.
