Wi-Fiルーターおすすめ by 妻

概要

  • ネットーワーク機器のマーケ担当をしてる妻から聞いた、Wi-Fiルータのオススメ（「同僚のメーカー担当ごとに己の”最強”を選んでもらった」とのこと）です
  • 「ルーターにはWi-Fiルータだけじゃなく他にもいろいろあるんだよ！これはWi-Fiルータのことね」と言われたのでタイトルを変えました
  • 「AXほにゃらら」は規格（AX = Wi-Fi 6）+速度の参考値とのことです
  • もともとの文脈: 家庭内の雑談をツイートしたところ（ https://twitter.com/__gfx__/status/1464084908091920387 ）知人が反応したので妻に「ルータのおすすめ教えてと知人がいってるのでなんか教えて」といって教えてもらったのが元です
  • 下にあるv1.md が最初のやつ（2021/11/26）で、このv2.md がホッテントリ入りしたあとの改訂版（2021/11/27）です

追記（2022/05/24）:

  • TP-Linkはちょいちょいやらかしがあります

Explain why 001-CVE-2021-23410 is invalid

CVE-2021-23410 is invalid because the PoC has nothing to do with the msgpack module and any other serializers.

The PoC is something like this:

var assert = require('assert');
var msgpack = require('msgpack');
function sleep(ms) {
return new Promise((resolve) => {
setTimeout(resolve, ms);
