KubeView <=0.1.31 - Information Disclosure

ID: CVE-2022-45933

Severity: critical

Author: For3stCo1d

Tags: cve,cve2022,kubeview,kubernetes,exposure,kubeview_project

Description

Section titled “Description”

KubeView through 0.1.31 is susceptible to information disclosure. An attacker can obtain control of a Kubernetes cluster because api/scrape/kube-system does not require authentication and retrieves certificate files that can be used for authentication as kube-admin. An attacker can thereby possibly obtain sensitive information, modify data, and/or execute unauthorized operations.
