CVE-2025-7342

A security issue was discovered in the Kubernetes Image Builder where default credentials are enabled during the Windows image build process when using the Nutanix or VMware OVA providers. These credentials, which allow root access, are disabled at the conclusion of the build. Kubernetes clusters are only affected if their nodes use VM images created via the Image Builder project and the vulnerability was exploited during the build process, which requires an attacker to access the build VM and modify the image while the build is in progress.
Configurations

Summary (en) A security issue was discovered in the Kubernetes Image Builder where default credentials are enabled during the image build process. Additionally, virtual machine images built using the Nutanix or the OVA 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 Windows nodes use VM images created via the Image Builder project with its Nutanix or OVA provider.

Summary
  • (es) Se detectó un problema de seguridad en Kubernetes Image Builder, donde las credenciales predeterminadas se habilitan durante el proceso de creación de la imagen. Además, las imágenes de máquinas virtuales creadas con Nutanix u OVA no deshabilitan estas credenciales predeterminadas, y los nodos que utilizan las imágenes resultantes pueden ser accesibles mediante estas credenciales. Estas credenciales se pueden usar para obtener acceso root. Los clústeres de Kubernetes solo se ven afectados si sus nodos de Windows usan imágenes de máquinas virtuales creadas mediante el proyecto Generador de Imágenes con su proveedor Nutanix u OVA.
