Go github.com/kubernetes-sigs/image-builder < 0.1.38
Fixed in
0.1.38· Vendor fix available
Issue
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.
Recommended action: Upgrade to 0.1.38 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.

Fixed in
0.1.38· Vendor fix available
Issue
A security issue was discovered in the Kubernetes Image Builder versions <= v0.1.37 where default credentials are enabled during the image build process when using the Nutanix, OVA, QEMU or raw providers. The credentials can be used to gain root access. The credentials are disabled at the conclusion of the image build process. Kubernetes clusters are only affected if their nodes use VM images created via the Image Builder project. Because these images were vulnerable during the image build process, they are affected only if an attacker was able to reach the VM where the image build was happening and used the vulnerability to modify the image at the time the image build was occurring.
Recommended action: Upgrade to 0.1.38 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
