Title

MongoDB must prohibit user installation of logic modules (stored procedures, functions, triggers, views, etc.) without explicit privileged status. (Cat II impact)

Discussion

Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceed the rights of a regular user. DBMS functionality and the nature and requirements of databases will vary; so while users are not permitted to install unapproved software, there may be instances where the organization allows the user to install approved software packages such as from an approved software repository. The requirements for production servers will be more restrictive than those used for development and research. MongoDB must enforce software installation by users based upon what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization). In the case of a database management system, this requirement covers stored procedures, functions, triggers, views, etc.

Check Content

If MongoDB supports only software development, experimentation, and/or developer-level testing (that is, excluding production systems, integration testing, stress testing, and user acceptance testing), this is not a finding. Review the MongoDB security settings with respect to non-administrative users' ability to create, alter, or replace functions or views. These MongoDB commands can help with showing existing roles and permissions of users of the databases. db.getRoles( { rolesInfo: 1, showPrivileges:true, showBuiltinRoles: true }) If any such permissions exist and are not documented and approved, this is a finding.

Fix Text

Revoke any roles with unnecessary privileges to privileged functionality by executing the revoke command. Revoke any unnecessary privileges from any roles by executing the revoke command. Create, as needed, new role(s) with associated privileges.
