Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The listed versions of Nexx Smart Home devices use hard-coded credentials. An attacker with unauthenticated access to the Nexx Home mobile application or the affected firmware could view the credentials and access the MQ Telemetry Server (MQTT) server and the ability to remotely control garage doors or smart plugs for any customer.
