Kubernetes Misconfiguration: HTTP Basic Authentication

YAML

Abstract

Kubernetes API サーバーは HTTP 基本認証を受け入れます。

Explanation

クラスターの中央管理エンティティである Kubernetes API サーバーは、HTTP 基本認証を受け入れてユーザーを認証します。HTTP 基本認証は非推奨であり、ブルートフォース攻撃の影響を受けやすく、誤って設定された環境では攻撃者にユーザー資格情報を漏らす可能性があります。

例 1: 次の設定では、Kubernetes API サーバーを起動し、--basic-auth-file=<filename>> フラグを HTTP 基本認証を使用するように設定します。


...
kind: Pod
...
spec:
  containers:
    - command:
      - kube-apiserver
      - --basic-auth-file=<filename>
    image: example.domain/kube-apiserver-amd64:v1.6.0
    livenessProbe:
...
