    🔐 Microsoft published a 10.0 CVE on Entra Device Registration — already fixed. No patch. No action required. What it doesn’t say: whether it was used before the fix.

    CVE・脆弱性ニュースまとめ ■国内 新たに対象となるものはありませんでした ■海外 ① Microsoft「Entra Device Registration」:認証のすり抜けで権限を昇格されうる脆弱性、CVSS 10.0。Microsoftがすでに対策済みで、利用者の対応は不要(CVE-2026-109469、CVSS v3.1 10.0) Microsoftが11月5日(米国時間)に公表し、日本時間の11月7日朝にNVDへ掲載された、クラウドサービス「Entra Device Registration」の脆弱性です。デバイス登録の処理で、利用者が操作できるキーの値を検証せずに認可してしまうため、権限のない攻撃者がネットワーク経由で権限を昇格できてしまうおそれがあります。Microsoftはすでにサービス側で完全に対策済みで、利用者側で行う対応はないとしており、悪用された報告も確認されていません。Entra IDを使っている組織でも、個別の更新や設定変更は必要ありません。 出典:CVE記録 https://www.cve.org/CVERecord?id=CVE-2026-109469 出典:Microsoft https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-109469 ② OpenSSH「OpenSSH」(続報):ハニーポットでroot権限の奪取を確認と報告、未更新のAlpine Linuxは更新を(CVE-2026-123158、CVSS v3.1 8.1) 11月6日の本日のまとめでは「実際の悪用の報告は確認できていません」とお伝えしましたが、その後、脅威インテリジェンス企業のPrevidianが、公開から9時間以内に最初の攻撃を観測し、Alpine LinuxとOpenSSHで動かすハニーポットでroot権限を奪われたと報告しました。観測された8回の試行はすべて日本国内の1つのIPアドレス(89.116.89.18)からで、256バイトを超える長いパスワードで認証をすり抜け、idやuname、hostnameといった偵察用のコマンドを実行したということです。修正版はOpenSSH 10.6p2とAlpine Linuxの各ブランチ向け修正パッケージで、更新後はsshdの再起動が必要です。米CISAのKEVカタログにはまだ追加されていません。攻撃コードもGitHubに公開されていますが、未検証のものにはマルウェアが混入しているおそれがあるとPrevidianは注意しています。 出典:CVE記録 https://www.cve.org/CVERecord?id=CVE-2026-123158 出典:Alpine Linux https://alpinelinux.org/posts/2026-11-05-openssh-password-authentication-bypass/ 出典:Help Net Security https://www.helpnetsecurity.com/2026/11/06/openssh-sshole-cve-2026-123158-exploitation/ ■注意点 ・Microsoft Entra Device Registration(CVE-2026-109469)はCVSS 10.0ですが、Microsoftがすでに対策済みで利用者の対応は不要です。個別の更新や設定変更は必要ありません。 ・OpenSSH(CVE-2026-123158)は、ハニーポットでroot権限の奪取が確認されたと報告されました。Alpine Linuxなどでsshdを公開している環境は、OpenSSH 10.6p2への更新とsshdの再起動、またはパスワード認証の無効化を行ってください。 #脆弱性 #CVE #サイバーセキュリティ
