NoSQL Injection

Summary

NoSQL Injection is a type of application attack that targets NoSQL databases by exploiting improper input validation to manipulate database queries, allowing attackers to access, modify, or delete data unauthorizedly.

Key Characteristics

• Targets NoSQL databases such as MongoDB, CouchDB, and Cassandra.
• Exploits vulnerabilities in query construction by injecting malicious input.
• Bypasses traditional SQL injection defenses due to differences in query languages.
• Can lead to unauthorized data access, data corruption, or privilege escalation.
• Often involves injection of JSON-like or JavaScript code fragments into queries.

Defensive Controls

• Implement strict input validation and sanitization to prevent malicious payloads.
• Use parameterized queries or prepared statements designed for NoSQL databases.
• Apply the principle of least privilege to database user accounts.
• Regularly update and patch NoSQL database software to fix known vulnerabilities.
• Employ web application firewalls (WAFs) with NoSQL injection detection capabilities.

Related Security Solutions

Security solutions related to NoSQL Injection include Web Application Firewalls (WAFs), runtime application self-protection (RASP) tools, database activity monitoring (DAM) systems, and secure coding practices frameworks that emphasize input validation and query parameterization.
