How to Fix CVE-2018-1002103

To remediate this vulnerability, upgrade all affected K8s.io/minikube dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

k8s.io/minikube fixed: Latest secure release 
Upgrade k8s.io/minikube to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for k8s.io/minikube

How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-1002103, inspect your project dependencies for K8s.io/minikube:

inspect dependencies for k8s.io/minikube

Analyze the terminal output to locate any version of K8s.io/minikube in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In K8s.io/minikube, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
