Title

If passwords are used for authentication, MongoDB must transmit only encrypted representations of passwords. (Cat I impact)

Discussion

The DoD standard for authentication is DoD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires AO approval. In such cases, passwords need to be protected at all times and encryption is the standard method for protecting passwords during transmission. DBMS passwords sent in clear text format across the network are vulnerable to discovery by unauthorized users. Disclosure of passwords may easily lead to unauthorized access to the database.

Check Content

In the MongoDB database configuration file (default location: /etc/mongod.conf), review the following parameters: net: ssl: mode: requireSSL PEMKeyFile: /etc/ssl/mongodb.pem CAFile: /etc/ssl/mongodbca.pem If the "CAFile" parameter is not present, this is a finding. If the "allowInvalidCertificates" parameter is found, this is a finding. net: ssl: allowInvalidCertificates: true

Fix Text

In the MongoDB database configuration file (default location: /etc/mongod.conf) ensure the following parameters are set and configured correctly: net: ssl: mode: requireSSL PEMKeyFile: /etc/ssl/mongodb.pem CAFile: /etc/ssl/mongodbca.pem Remove any occurrence of the "allowInvalidCertificates" parameter: net: ssl: allowInvalidCertificates: true Stop/start (restart) the mongod or mongos instance using this configuration.
