The WPA2 implementation on the Belkin N900 F9K1104v1 router establishes a WPS PIN based on 6 digits of the LAN/WLAN MAC address, which makes it easier for remote attackers to obtain access to a Wi-Fi network by reading broadcast packets, a different vulnerability than CVE-2012-4366.

Belkin wireless routers Surf N150 Model F7D1301v1, N900 Model F9K1104v1, N450 Model F9K1105V2, and N300 Model F7D2301v1 generate a predictable default WPA2-PSK passphrase based on eight digits of the WAN MAC address, which allows remote attackers to access the network by sniffing the beacon frames.
