Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
CWE
  • CWE-798 - Use of Hard-coded Credentials
Summary
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.
