CVE-2012-4366: Belkin wireless routers Surf N150 Model F7D1301v1, N900 Model F9K1104v1, N450 Model F9K1105V2, and N300 Mod...

Security readout for executives and security teams

Some Belkin router models shipped with a default Wi-Fi password that could be predicted from device MAC address information. If the owner never changed that password, someone within wireless range could potentially join the network. This is most urgent for legacy home, branch, or small-office routers still using factory settings. Exposure is likely limited to the listed Belkin router models where the factory WPA2 passphrase remains in use. Devices with changed unique Wi-Fi passwords are less exposed to this specific weakness. Enterprise impact is mostly through unmanaged branch, lab, guest, or employee home networks. Prioritize remediation where affected routers protect business, remote-work, or branch networks. The issue is old and not KEV-listed, but unchanged default Wi-Fi credentials can still expose internal traffic and systems to anyone nearby. Mitigation focus: Inventory for the specific Belkin models named in the CVE.; Replace factory Wi-Fi passwords with unique, strong WPA2 or WPA3 passphrases.; Check Belkin or successor vendor guidance for firmware or replacement recommendations..
