| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Ignition versions prior to 2.14.0
Description
A vulnerability was found in Ignition where ignition configs are accessible from unprivileged containers in VMs running on VMware products. This issue is only relevant in user environments where the Ignition config contains secrets. The highest threat from this vulnerability is to data confidentiality.
Recommendations
For Ignition versions prior to 2.14.0, consider upgrading to Ignition 2.14.0 or later, which adds a new systemd service,
ignition-delete-config.service, that deletes the Ignition config from supported hypervisors during the first boot.
As a temporary workaround, avoid storing secrets in Ignition configs.
If you have external tooling that requires the Ignition config to remain accessible in VM metadata after provisioning, and your Ignition config does not include sensitive information, you can prevent Ignition 2.14.0 and later from deleting the config by masking ignition-delete-config.service.Fix
