Weakness

What to do

Solution: NETGEAR strongly advises against allowing untrusted users or devices on your WiFi network. The NETGEAR C6220 has reached End-of-Support (EOS) and C6230 will reach EOS soon. Due to limited security impact (device reboots only), no fixes are planned.

Workaround: The users are advised to not allow untrusted devices to connect to the Wi-fi Network.

Exploitation: We are not aware of any exploitation.
