NoSQL Injection Basics: NoSQL DoS and Exfiltration with OWASP Juice Shop

Lab overview

NoSQL injection is a critical security vulnerability that affects applications using NoSQL databases like MongoDB, Cassandra, and CouchDB. Unlike traditional SQL databases, NoSQL databases are particularly vulnerable to different types of injection attacks due to their flexible query structure and JavaScript execution capabilities.

In this lab, you will explore two powerful NoSQL injection techniques using the OWASP Juice Shop application: a DoS attack using the sleep() function and a data exfiltration attack using logical operators. These hands-on exercises will demonstrate the real-world impact of NoSQL injection vulnerabilities.

Objectives

Upon completion of this lab, you will be able to:

  • Understand how NoSQL injection vulnerabilities can be exploited
  • Perform a DoS attack using NoSQL sleep() function injection
  • Execute a data exfiltration attack using NoSQL logical operator injection
  • Implement proper security measures to prevent NoSQL injection attacks

Who is this lab for?

This lab is designed for:

  • Web developers working with NoSQL databases
  • Security professionals learning about modern database vulnerabilities
  • Application security testers expanding their knowledge of injection attacks
  • DevOps engineers responsible for securing database operations
