NoSQL Injection

NoSQL Injection is a critical vulnerability within the Payload Execution phase, specifically targeting Injection Exploitations. Unlike traditional SQL injection attacks that target relational databases, NoSQL injection exploits design flaws in non-relational database implementations by manipulating query parameters to execute unintended operations. Attackers leverage this technique to bypass authentication mechanisms, extract sensitive data, or execute privileged operations by injecting malicious code into application queries that interact with NoSQL databases such as MongoDB, Cassandra, CouchDB, or Redis. The attack typically exploits applications that construct NoSQL queries using unsanitized user input, allowing attackers to modify query operators (such as $gt, $where, or $ne in MongoDB) to alter query logic and expose functionality beyond intended boundaries. This exploitation technique can lead to complete database compromise, unauthorized access to protected resources, and in some cases, even remote code execution when combined with other vulnerabilities, making it particularly dangerous in modern web and mobile applications that rely on NoSQL database infrastructure for data storage and retrieval.
