ProjectDiscoveryCRITICALKubeView <=0.1.31 - Information DisclosureCVSS 9.8

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.

Impact

Unauthenticated attackers can access Kubernetes certificate files through the unauthenticated api/scrape/kube-system endpoint, potentially obtaining kube-admin credentials and gaining complete control over the Kubernetes cluster.

Remediation

Upgrade KubeView to a version higher than 0.1.31 to mitigate the information disclosure vulnerability (CVE-2022-45933).
