Minikube RCE via DNS Rebinding

High severity GitHub Reviewed Published May 13, 2022 to the GitHub Advisory Database • Updated Jul 21, 2023

Package

gomod k8s.io/minikube (Go)

Affected versions

>= 0.3.0, <= 0.29.0

Patched versions

None

Description

In Minikube versions 0.3.0-0.29.0, minikube exposes the Kubernetes Dashboard listening on the VM IP at port 30000. In VM environments where the IP is easy to predict, the attacker can use DNS rebinding to indirectly make requests to the Kubernetes Dashboard, create a new Kubernetes Deployment running arbitrary code. If minikube mount is in use, the attacker could also directly access the host filesystem.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
