MongoDB Injection 01
This exercise is one of our challenges on vulnerabilities related to MongoDB
In this lab, you will learn how to exploit MongoDB authentication mechanisms using NoSQL injection techniques. The exercise begins with a simple login prompt where traditional SQL injection methods are adapted to fit MongoDB's query syntax. You'll explore how to create always-true conditions with || 1==1 and use terminators like null bytes to bypass the remainder of the query.
The video tutorial walks you through the process step-by-step, starting with basic injection attempts and progressively refining the approach until successful authentication bypass is achieved. This hands-on experience is crucial for understanding the subtle differences between SQL and NoSQL databases and how common injection techniques can be adapted for different systems. By the end of the lab, you'll have a solid grasp of both the theory and practical application of NoSQL injection in MongoDB contexts.
