Weaknesses

  • CWE-269: CWE-269 Improper Privilege Management

Workarounds

Best practice is for generated device onboarding tokens to be valid for a limited time duration, and for the Device Onboarding permission which allows the generation of these tokens to only be granted to trusted users.

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.
