Beschreibung:Summary:
The script checks if the Kubernetes Dashboard UI is accessible
from a public WAN (Internet) / public LAN.

Vulnerability Insight:
The installation of Kubernetes Dashboard might be incomplete and
therefore unprotected and exposed to the public.

Vulnerability Impact:
Access to the dashboard gives you top level access to all aspects
of administration for the cluster it is assigned to manage. That includes managing applications,
containers, starting workloads, adding and modifying applications, and setting key security
controls.

Solution:
It is highly recommended to consider the following:

- Regardless of network policy, use MFA for all access.

- Apply strict controls to network access, especially for UI and API ports.

- Use SSL/TLS for all servers and use valid certificates with proper expiration and enforcement
policies.

- Investigate VPN (bastion), reverse proxy or direct connect connections to sensitive servers.

- Look into product and services such as Lacework in order to discover, detect, prevent, and
secure your container services.

But most importantly:

- Configure your Kubernetes pods to run read-only file systems.

- Restrict privilege escalation in Kubernetes.

- Build a pod security policy.

CVSS Score:
