The websocket configuration endpoint of the Loxone Miniserver Go Gen.2 before 14.1.5.9 allows remote authenticated administrators to inject arbitrary OS commands via the timezone parameter.

The root password of the Loxone Miniserver Go Gen.2 before 14.2 is calculated using hard-coded secrets and the MAC address. This allows a local user to calculate the root password and escalate privileges.

Loxone Miniserver Go Gen.2 through 14.0.3.28 allows an authenticated operating system user to escalate privileges via the Sudo configuration. This allows the elevated execution of binaries without a password requirement.

Loxone Miniserver devices with firmware before 11.1 (aka 11.1.9.3) are unable to use an authentication method that is based on the "signature of the update package." Therefore, these devices (or attackers who are spoofing these devices) can continue to use an unauthenticated cloud service for an indeterminate time period (possibly forever). Once an individual device's firmware is updated, and authentication occurs once, the cloud service recategorizes the device so that authentication is subsequently always required, and spoofing cannot occur.
