Is this vulnerability remotely exploitable?

Yes, once an attacker has extracted the hard-coded administrative credentials from the app, firmware, or API responses, they can typically authenticate remotely to the IoT hub or associated cloud services, assuming they are network-accessible.

What level of access does an attacker need to exploit this?

The attacker needs only the ability to obtain the mobile application package, firmware image, or observe API responses—capabilities that are commonly achievable without prior authentication, especially for publicly distributed apps or update packages.

What is the safest general fix pattern for this issue?

Remove all hard-coded administrative credentials and move to a model that uses unique, server-managed, and revocable credentials or tokens per device or user, combined with strong authentication and least-privilege authorization.
