CVE-2024-45497
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw was found in the OpenShift build process, where the docker-build container is configured with a hostPath volume mount that maps the node's /var/lib/kubelet/config.json file into the build pod. This file contains sensitive credentials necessary for pulling images from private repositories. The mount is not read-only, which allows the attacker to overwrite it. By modifying the config.json file, the attacker can cause a denial of service by preventing the node from pulling new images and potentially exfiltrating sensitive secrets. This flaw impacts the availability of services dependent on image pulls and exposes sensitive information to unauthorized parties.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOpenShift's docker-build container mounts the node's /var/lib/kubelet/config.json (containing private registry credentials) as a writable hostPath volume into build pods. This allows attackers with build pod access to modify or exfiltrate the credentials, causing denial of service (preventing image pulls) and potential secret exfiltration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify OpenShift docker-build BuildConfigsRun 'oc get bc --all-namespaces -o json' to list all BuildConfigs and filter for those with 'strategy.type: Docker' or 'strategy.dockerStrategy' definedAffected if BuildConfigs exist with docker strategy and reference a registry credentials secret or mount the node's config.json
-
Inspect the BuildConfig volume mount configurationRun 'oc get bc <name> -n <namespace> -o json' and examine spec.strategy.dockerStrategy.volumes or the build pod spec to see if hostPath volumes are defined for /var/lib/kubelet/config.jsonAffected if A hostPath volume is defined mounting /var/lib/kubelet/config.json into build pods
-
Check if the hostPath volume is mounted as writableExamine the BuildConfig or build pod volume mount definition - look for 'readOnly: false' or absence of 'readOnly: true' on the volume mount specification for the config.json pathAffected if The volume mount for config.json does not have readOnly: true set, meaning it is writable
-
Verify running build pods have the writable mountStart a test build with 'oc start-build <name> -n <namespace>' then inspect the pod with 'oc get pod <pod> -n <namespace> -o json' and check spec.containers[].volumeMounts for the config.json mount and its readOnly settingAffected if The running build pod has /var/lib/kubelet/config.json mounted without readOnly: true
Your environment is affected if you use OpenShift docker-build strategy and the /var/lib/kubelet/config.json is mounted as a writable hostPath volume into build pods, allowing credential modification or theft.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataConfigure the hostPath volume mount as read-only (readOnly: true) or replace it with a projected secret volume to prevent unauthorized write access to the kubelet config.json file.
