Kubernetes Misconfiguration: Missing Kubelet Authorization

YAML

Abstract

Kubelet は、リクエストの承認を必要としません。

Explanation

Kubelet は、AlwaysAllow モードまたは Webhook モードを使用してリクエストを承認します。未指定の承認モードはデフォルトで AlwaysAllow になります。Kubelet は、すべてのリクエストを許可する AlwaysAllow モードでは承認チェックを実行しません。Kubelet はワーカーマシンのワークロードを管理する Kubernetes の主要なエージェントであるため、攻撃者は、制御されないリクエストを使用して、保護が不十分でセキュリティが重要なサービス API にアクセスできます。

例 1: 承認モードが AlwaysAllow に設定されているため、Kubelet は承認チェックを実行しません。

Kubernetes Misconfiguration: Missing Kubelet Certificate Authentication

YAML

Abstract

Kubelet の HTTPS エンドポイントに対する X509 クライアント証明書の認証が定義されていません。

Explanation

Kubelet はクライアントを認証できますが、クライアント証明書の検証に使用される認証局 (CA) バンドルが Kubelet 構成で定義されていません。Kubelet はワーカーマシンのワークロードの管理に使用される Kubernetes の主要なエージェントであるため、攻撃者は、匿名リクエストを使用して、保護が不十分でセキュリティが重要なサービス API にアクセスできます。

例 1: 次の Kubelet 構成には、クライアント証明書の検証に使用される CA バンドルを指定する、clientCAFile フィールドが含まれていません。

Kubernetes Misconfiguration: Missing Kubelet Client Certificate

YAML

Abstract

Kubernetes API サーバーは、Kubelet の HTTPS エンドポイントに対して自身を認証しません。

Explanation

デフォルトでは、Kubernetes API サーバーは、リクエストを送信するときに Kubelet に対して自身を認証しません。さまざまなリソースへのアクセスを提供する Kubelet は、それらのリクエストの真正性を確認できません。

例 1: 次のコマンドは、Kubelet に対する証明書ベースの認証を有効にするために --kubelet-client-certificate フラグと --kubelet-client-key フラグを使用してクライアント証明書と対応する秘密鍵を指定せずに、Kubernetes API サーバーを起動します。

Kubernetes Misconfiguration: Missing Kubelet Identity Verification

YAML

Abstract

Kubernetes API サーバーが SSL 接続を確立すると、Kubelet のサーバー ID 検証が無効になります。

Explanation

Kubernetes API サーバーは、ワークロードを作成するための指示を Kubelet に送信し、Kubelet が管理するリソースのステータスを照会し、オプションのポート転送サービスを Kubelet に提供します。デフォルトでは、API サーバーは接続を確立する前に Kubelet のサービング証明書を確認しません。そのため、この接続は中間者 (Man-in-the-Middle) 攻撃を受けやすくなります。

例 1: 次のコマンドは、ルート証明書バンドルを指定せずに Kubernetes API サーバーを起動して、Kubelet のサービング証明書を --kubelet-certificate-authority フラグで確認します。

Kubernetes Misconfiguration: Missing Node Authorization

YAML

Abstract

Kubernetes API サーバーは、Kubelet によるリクエストの承認にノードモードを使用しません。

Explanation

Kubernetes API サーバーは、いくつかの承認モードの 1 つを使用してリクエストを承認できます。Node 承認は、Kubelet による API リクエストを承認することを目的とした、特別な承認モードです。これにより、Kubelet が正しく動作するのに必要な、最小限の権限セットを持つことが保証されます。

例 1: 次の設定では、Node 承認モードなしで、Kubernetes API サーバーを起動します。


...
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --authorization-mode=RBAC,Webhook
    ...

Kubernetes Misconfiguration: Missing NodeRestriction Admission Controller

YAML

Abstract

Kubernetes API サーバーを起動するコマンドが、NodeRestriction アドミッションコントローラーを有効にしません。

Explanation

NodeRestriction アドミッションコントローラーを、Kubernetes API サーバー用に常に有効にしてください。NodeRestriction アドミッションコントローラーは、すべての Kubelet に対して Node オブジェクトと Pod オブジェクトを変更することを制限するとともに、機密性の高いシステムオブジェクトへのアクセスを拒否します。これにより、侵害されたノードが Kubernetes クラスターの他のノードで特権を取得するのを防ぎます。

例 1: 次の Pod 定義では、NodeRestriction アドミッションコントローラーを有効にせずに、Kubernetes API サーバーを起動します。


apiVersion: v1
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --enable-admission-plugins=PodSecurityPolicy
    ...

Kubernetes API サーバーを起動するコマンドが、PodSecurityPolicy アドミッションコントローラーを有効にしません。

Explanation

PodSecurityPolicy アドミッションコントローラーがないと、K-Rail、Kyverno、OPA/Gatekeeper など、Kubernetes 用の別のポリシー適用ツールがない限り、セキュリティコントロールが脆弱になります。PodSecurityPolicy アドミッションコントローラーは、クラスター内の許容されるセキュリティ関連の Pod 属性を指定する、Pod セキュリティポリシーを適用します。たとえば、PodSecurityPolicy を使用して、特権コンテナーを禁止し、Pod が作成されるときにデフォルトで特権昇格を禁止できます。

例 1: 次の Pod 定義では、PodSecurityPolicy アドミッションコントローラーを有効にせずに、Kubernetes API サーバーを起動します。


apiVersion: v1
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --enable-admission-plugins=NodeRestriction
    ...

Kubernetes Misconfiguration: Missing RBAC Authorization

YAML

Abstract

Kubernetes API サーバーは、ロールベースのアクセス制御 (RBAC) を使用しません。

Explanation

Kubernetes API サーバーは、いくつかの承認モードの 1 つを使用してリクエストを承認できます。ロールベースのアクセス制御 (RBAC) は、組織内の個々のユーザーのロールに基づいて、コンピューターまたはネットワークリソースへのアクセスを制御します。RBAC は最も安全な承認モードです。

例 1: 次の設定では、RBAC 承認モードなしで、Kubernetes API サーバーを起動します。


...
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --authorization-mode=Node,Webhook
    ...
