Kubernetes Misconfiguration: HTTP Basic Authentication

YAML

Abstract

Kubernetes API 서버가 HTTP 기본 인증을 수락합니다.

Explanation

클러스터의 중앙 관리 엔터티인 Kubernetes API 서버가 HTTP 기본 인증을 수락하여 사용자를 인증합니다. HTTP 기본 인증은 더 이상 사용되지 않으며 무차별 대입 공격에 취약하고 잘못 구성된 환경에서 공격자에게 사용자 자격 증명을 유출합니다.

예제 1: 다음 구성은 Kubernetes API 서버를 시작하고--basic-auth-file=<filename>> 플래그를 설정하여 HTTP 기본 인증을 사용합니다.


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