Workarounds

CNA: The vendor does not consider this a defect and has stated it will not be fixed, so the device's built-in role separation cannot be relied upon. As a mitigation, treat every account on the device as an administrator-equivalent account. Additionally, restrict network access to the device management interface to trusted administrators only.
