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 · unedited
A vulnerability was found in OpenShift builds, versions 4.1 up to 4.3. Builds that extract source from a container image, bypass the TLS hostname verification. An attacker can take advantage of this flaw by launching a man-in-the-middle attack and injecting malicious content.

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 · moderate confidence

In OpenShift versions 4.1 through 4.3, build processes that extract source code from container images fail to perform TLS hostname verification. While TLS encryption may be established, the hostname is not validated against the certificate, enabling an attacker positioned on the network path to perform a man-in-the-middle attack and inject malicious content into the build process.

MitigationUpgrade to OpenShift 4.4 or later, or ensure builds using container image sources are configured to enforce proper TLS hostname verification to prevent MITM attacks.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check OpenShift cluster version
    Run 'oc get clusterversion' or 'oc version' to identify the installed OpenShift version number
    Affected if Version is 4.1, 4.2, or 4.3 (any version >= 4.1 and <= 4.3)
  2. Identify builds using container image sources
    Run 'oc get buildconfigs --all-namespaces' to list all BuildConfig resources, then inspect each with 'oc get buildconfig <name> -n <namespace> -o yaml' to check the 'spec.source.type' field
    Affected if Any BuildConfig has 'source.type' set to 'Image' or references an ImageStreamTag or DockerImage as the source
  3. Check for source pull secrets using external registries
    Examine BuildConfigs for 'spec.source.pullSecret' entries that reference external container registries (not internal ImageStream secrets). Use 'oc get buildconfig <name> -n <namespace> -o jsonpath={.spec.source.pullSecret}'
    Affected if Builds pull source images from external registries using secrets configured for those registries
  4. Verify TLS certificate validation is enforced
    Review build logs or build pod specifications for evidence of TLS hostname verification. Check if the build process uses a transport that validates hostnames when pulling container images
    Affected if No explicit TLS hostname verification is configured or the build uses a transport that skips hostname validation for image pulls

You are affected if your OpenShift version is 4.1, 4.2, or 4.3 AND you have builds configured to use container images as source from any registry.
