Successful exploit generally requires one of the following: * A rogue or compromised internal user with Device enrollment read/write permissions OR,   * A valid device onboarding token that is easily accessible beyond the expected set of trusted users If all users with Device Onboarding privileges are trusted, and onboarding tokens are properly secured, then the risk of this issue is limited.
