What it is

Improper handling of case sensitivity in the configuration validation component of MongoDB Server may cause the authorization subsystem to remain in a default disabled state during server startup. An unauthenticated user with network access to a deployment where this condition occurs can perform arbitrary administrative operations, resulting in full impact of data confidentiality, integrity, and availability.
