界: Security Features

ソフトウェアのセキュリティは、セキュリティソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Unauthenticated Service: Redis

Java/JSP

Abstract

アプリケーションは、認証情報を設定せずに Redis クライアントを初期化します。

Explanation

未認証の Redis サーバーは、攻撃者がサーバーのセキュリティを侵害して内部ネットワークに侵入するための標的になることがあります。

Redis サーバーに対して各種攻撃を使用し、基盤となるオペレーティングシステム上で任意のコードを実行することができます。たとえば、攻撃者は Redis コマンドを使用して Web シェルを Web ルートに書き込むことができます。また、オブジェクトを格納するためにコマンドを使用する場合、攻撃者はデシリアライズするエンドポイント上でリモートコードを実行するために、Java、Python、Ruby、PHP などの各言語のデシリアライズペイロードを格納することができます。

Redis サーバーが外部に公開されていない場合でも、外部の攻撃者は同じネットワーク上の任意のアプリケーションで Server-Side Request Forgery の脆弱性を利用してサーバーにアクセスできることに注意してください。たとえば Redis サーバーは、HTTP または Gopher プロトコルを使用して攻撃される可能性があります。

外部の攻撃から Redis ポートを保護しないと、Redis の性質上、セキュリティ上の大きな影響が発生する可能性があります。たとえば、単一の FLUSHALL コマンドを使用して、外部の攻撃者はデータセット全体を削除することができます。最近、インターネット上で実行しているオープンな Redis の安全ではないインスタンスに対する悪意のある攻撃が報告されています。攻撃者はデータベースを消去し、復元のために身代金を支払うよう要求しました。
