CVE-2024-9486
kubernetes-image-builder: VM images built with Kubernetes Image Builder use default credentials
Severity by source
Trivy's own label is CRITICAL. Rated critical by NVD, GHSA, Red Hat, Kubernetes.
Description
A security issue was discovered in the Kubernetes Image Builder versions <= v0.1.37 where default credentials are enabled during the image build process. Virtual machine images built using the Proxmox provider do not disable these default credentials, and nodes using the resulting images may be accessible via these default credentials. The credentials can be used to gain root access. Kubernetes clusters are only affected if their nodes use VM images created via the Image Builder project with its Proxmox provider.
