Is this vulnerability remotely exploitable over the internet?

Typically, exploitation requires proximity to the wireless network, since the attacker must send crafted deauth frames within radio range of the device. Indirect internet-based exploitation would depend on additional weaknesses in remote access or cloud integration that are not implied by this issue alone.

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

The attacker generally needs physical proximity sufficient to interact with the Wi‑Fi network (e.g., within range of the fan's access point or connected router). They do not necessarily need to know the Wi‑Fi password to transmit spoofed deauth frames, but further privilege escalation may depend on subsequent protocol behavior.

What is the safest general fix pattern for vendors?

Vendors should harden the firmware's authentication and session handling logic around deauth and reconnection, ensuring that no privileged operations or sensitive data are exposed without explicit, validated credentials. Recovery or pairing modes should be tightly scoped, rate-limited, and designed so that they never implicitly trust network events like deauth as a signal to relax security.
