Blind NoSQL Injection (differential analysis)

Synopsis

Description

A NoSQL injection occurs when a value originating from the client's request is used within a NoSQL call without prior sanitisation.

This can allow cyber-criminals to execute arbitrary NoSQL code and thus steal data, or use the additional functionality of the database server to take control of further server components.

Scanner discovered that the affected page and parameter are vulnerable. This injection was detected as scanner was able to inject specific NoSQL queries that if vulnerable result in the responses for each injection being different. This is known as a blind NoSQL injection vulnerability.

Solution

The most effective remediation against NoSQL injection attacks is to ensure that NoSQL API calls are not constructed via string concatenation that includes unsanitized data.
Sanitization is best achieved using existing escaping libraries.
