AP Firmware release 184.108.40.206.39
AP firmware Version: 220.127.116.11.39
Model: Xi-1/2/3 and Xo-1
Release date: 11/05/2017
This AP firmware release addresses security vulnerabilities related to the 4-way handshake of WPA and WPA2 protocols key reinstallation attacks (KRACKs).
Exploitation of these vulnerabilities may ultimately allow decryption of AP-client traffic, packet replay, TCP connection hijacking,
and HTTP content injection. Due to these vulnerabilities, Wi-Fi Protected Access II (WPA2) handshake traffic can be manipulated to allow
nonce and session key reuse, resulting in key reinstallation on a targeted wireless access point (AP) or client.
We recommend all the users to upgrade the AP’s to the latest firmware by rebooting the AP’s twice in space of 10 minutes.
