Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.

No authentication or controls are in place to prevent a threat actor from maliciously modifying firmware and performing a drive-by attack to load the firmware on any CMS8000 device.
