NoSQL Injection - MongoDB

Remediation

1. Input validation: Always validate and sanitize user input before using it in a MongoDB query. This can help prevent malicious code injection.
2. Parameterized queries: Use parameterized queries or prepared statements to ensure that user input is treated as data and not executable code. This can help protect against injection attacks.
3. Least privilege principle: Ensure that the MongoDB user account used by the application has the minimum necessary privileges to perform its intended tasks. This can limit the potential impact of an injection attack.

About

MongoDB query injection is a vulnerability that occurs when user-supplied input is not properly validated or sanitized before being used in a MongoDB query. This can allow an attacker to manipulate the query and potentially execute arbitrary code or access unauthorized data.

Risks

1. Data exposure: An attacker may be able to retrieve sensitive data from the database by injecting malicious code into a MongoDB query.
2. Data modification: Injection attacks can also allow an attacker to modify or delete data in the database, potentially leading to data loss or unauthorized changes.
3. Application compromise: If an attacker is able to execute arbitrary code through a MongoDB injection, they may be able to gain control over the application and perform further malicious actions.
