What is CVE-2018-1002103?
CVE-2018-1002103 is a high-severity vulnerability in Kubernetes Minikube, published on 5 Dec 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-352
