Detailsinfo

A vulnerability has been found in kubernetes-sigs image-builder (the affected version unknown) and classified as critical. This vulnerability affects an unknown part. The manipulation with an unknown input leads to a default credentials vulnerability. The CWE definition for the vulnerability is CWE-1392. The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at seclists.org. This vulnerability was named CVE-2024-9594. The exploitation appears to be difficult. The attack needs to be done within the local network. Additional levels of successful authentication are necessary for exploitation. The technical details are unknown and an exploit is not available.
