CVE-2018-14620
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 · uneditedThe OpenStack RabbitMQ container image insecurely retrieves the rabbitmq_clusterer component over HTTP during the build stage. This could potentially allow an attacker to serve malicious code to the image builder and install in the resultant container image. Version of openstack-rabbitmq-container and openstack-containers as shipped with Red Hat Openstack 12, 13, 14 are believed to be vulnerable.
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 confidenceThe OpenStack RabbitMQ container image uses insecure HTTP to retrieve the rabbitmq_clusterer component during the build stage. An attacker performing a man-in-the-middle attack could intercept the HTTP download and inject malicious code into the container image, compromising all deployments using that image.

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.
-
Locate RabbitMQ container build filesFind the Dockerfiles, build scripts, or CI configurations used to build the RabbitMQ container images in your environment. Search for files containing 'rabbitmq' and 'clusterer'.Affected if The build files reference HTTP URLs for downloading rabbitmq_clusterer component
-
Inspect build logs for HTTP downloadsReview build logs, CI output, or provenance records for the RabbitMQ container image creation. Look for network requests using HTTP protocol during the build stage.Affected if Build logs show HTTP (not HTTPS) connections to retrieve rabbitmq_clusterer
-
Check build environment network securityDetermine whether the build infrastructure had proper TLS/SSL inspection or if HTTP traffic could have been intercepted. Review proxy configurations and certificate handling during the image build.Affected if Build environment allowed unauthenticated HTTP downloads without MITM protection
-
Verify image provenanceExamine image manifests, SBOMs, or build attestations to confirm the integrity verification method used for the rabbitmq_clusterer component download.Affected if No cryptographic verification (HTTPS certificate validation) was performed on the downloaded component
You are affected if your RabbitMQ container images were built using HTTP downloads for the rabbitmq_clusterer component, enabling potential code injection via man-in-the-middle attack.
Generated from the published advisory. Verify against your own configuration.
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 dataReplace HTTP with HTTPS for the rabbitmq_clusterer component download in the container build process and rebuild the image. Verify the HTTPS endpoint authenticity through certificate validation.
