Many hackers know SQL injection. They completely ignore NoSQL injection. But let me tell you a recent adventure in an insurance company that yielded significant treasure using this very trick. Many still underestimate it, but NoSQL databases, particularly those like MongoDB, reveal a goldmine of vulnerabilities if you know where to look.
Firstly, How to Identify This?
How do you spot the opportunity for a NoSQL injection? It starts with a keen eye on the API endpoints. Whenever you see operations that interact with a MongoDB database, especially those using methods like find, aggregate, or update, that’s your cue to dig deeper. Here are some signs that you might be dealing with a vulnerable setup:
While exploring an insurance company’s database, I stumbled upon several vulnerabilities tucked away in their aggregation pipelines. The unsuspecting setup allowed me to manipulate queries in ways they never anticipated. Here’s how I did it:
I started by sending seemingly harmless requests to a policy lookup endpoint:
With a simple payload
Once the system responded, I noticed the lack of basic input validation. I couldn't resist the urge to switch gears, injecting a payload using
Suddenly, I had access to all the policies! Data poured in, detailing every client and their coverage options, like pearls from an oyster.
NoSQL vulnerabilities are often overlooked, yet they can be just as lucrative as their SQL counterparts. By honing in on the unique characteristics of NoSQL databases, you can uncover hidden treasures.
