Kubernetes Misconfiguration: Static Authentication Token

YAML

Abstract

Kubernetes API 伺服器使用靜態權杖來驗證要求。

Explanation

Kubernetes API 伺服器透過將持有人權杖與保存在靜態權杖檔案中的清單進行比較來驗證要求。權杖檔案以純文字形式儲存機密，屬於靜態性質。以靜態權杖為基礎的驗證容易受到暴力破解攻擊，在錯誤設定的環境中，可能會將存取憑證洩露給攻擊者。若要新增、取代或撤銷權杖，您必須重新啟動 API 伺服器。

範例 1：以下組態將使用 --token-auth-file 旗標，啟動一部 Kubernetes API 伺服器來透過靜態權杖來驗證要求。


...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --token-auth-file=<filename>
    ...
