TP-LinkはArcherシリーズのルーター3製品に存在する深刻な脆弱性3件を修正した。最も重大なのは、認証なしでOSコマンドを実行できる「CVE-2026-9254」で、LAN内の攻撃者がroot権限を取得できる。影響するのはArcher BE800 v1、Archer BE3600 v1、Archer AX75 v1。CVE-2026-9254はペアレンタルコントロール機能で特殊文字の処理が不十分なため、特定パラメータへ任意のシェルコマンドを注入できる。 CVE-2026-16348は、認証済み管理者がVPN接続を通じてコマンドを注入できる脆弱性。CVE-2026-78541は保存型のコマンドインジェクションで、管理者権限を持つ攻撃者が細工したプロファイル名を保存すると、日次のクラウドレポート生成時にコマンドが実行される。 TP-LinkはそれぞれArcher BE800 v1向けに1.4.2 Build 260708、BE3600 v1向けに1.2.6 Build 20260617、AX75 v1向けに1.1.6 Build 260716を公開した。記事によると、実際の攻撃での悪用は確認されていない。 https://securityonline.info/cve-2026-9254-unauthenticated-os-command-injection/
