SV-96601r1_rule MongoDB must prevent unauthorized and unintended information transfer via shared system resources.

Vulnerability discussion

The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a shared system resource (e.g., registers, main memory, secondary storage) after the resource has been released back to the information system. Control of information in shared resources is also referred to as object reuse.Satisfies: SRG-APP-000243-DB-000373, SRG-APP-000243-DB-000374

Check content

Verify the permissions for the following database files or directories: MongoDB default configuration file: "/etc/mongod.conf" MongoDB default data directory: "/var/lib/mongo" If the owner and group are not both "mongod", this is a finding. If the file permissions are more permissive than "755", this is a finding.

Fix text

Correct the permission to the files and/or directories that are in violation. MongoDB Configuration file (default location): chown mongod:mongod /etc/mongod.conf chmod 755 /etc/mongod.conf MongoDB data file directory (default location): chown -R mongod:mongod/var/lib/mongo chmod -R 755/var/lib/mongo

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
