MD7X-00-009000 When invalid inputs are received, MongoDB must behave in a predictable and documented manner that reflects organizational and system objectives.

Information

A common vulnerability is unplanned behavior when invalid inputs are received. This requirement guards against adverse or unintended system behavior caused by invalid inputs, where information system responses to the invalid input may be disruptive or cause the system to fail into an unsafe state.

The behavior will be derived from the organizational and system requirements and includes, but is not limited to, notification of the appropriate personnel, creating an audit record, and rejecting invalid input.

This calls for inspection of application source code, which will require collaboration with the application developers. It is recognized that in many cases, the database administrator (DBA) is organizationally separate from the application developers, and may have limited, if any, access to source code. Nevertheless, protections of this type are so important to the secure operation of databases that they must not be ignored. At a minimum, the DBA must attempt to obtain assurances from the development organization that this issue has been addressed and must document what has been discovered.

MongoDB schema validation allows database administrators to create rules at the collection level for fields, specifying allowed data types and value ranges. This is distinct from application-level checks and input validation. It is particularly important in MongoDB due to its flexible schema model, which allows documents in a collection to have different fields and data types by default.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Document validation can be added at the time of creation of a new collection.

Also, existing collections can be modified with document validation rules.

Use the "validator" option to create or update a collection with the desired validation rules.

Refer to Schema Validation documentation for details:
