CVE-2018-1070
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 · uneditedrouting before version 3.10 is vulnerable to an improper input validation of the Openshift Routing configuration which can cause an entire shard to be brought down. A malicious user can use this vulnerability to cause a Denial of Service attack for other users of the router shard.
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 confidenceOpenShift routing before version 3.10 contains an improper input validation vulnerability in the routing configuration processing. A malicious user can craft invalid input that causes the entire router shard to fail, resulting in a denial of service for all users relying on that shard.

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.
-
Check OpenShift versionRun 'oc version' or 'openshift version' to determine the installed OpenShift Container Platform version. Alternatively, check the openshift-ansible package version or the OCP release version in use.Affected if The reported version is earlier than 3.10 (for example, 3.9, 3.7, 3.6, etc.)
-
Verify router component is deployedRun 'oc get pods -n default -l router' or 'oc get deploymentconfig router -n default' to confirm the OpenShift router is deployed in the environment.Affected if Router pods or router deploymentconfig exists, indicating the routing layer is active and could be exploited.
-
Check for custom router configurationInspect router configuration by running 'oc get configmap router -n default -o yaml' or examining any custom route specifications with 'oc get routes --all-namespaces' to see if user-defined routes exist.Affected if Custom route configurations are present, providing potential vectors for malicious input that could trigger the validation failure.
The environment is affected if the installed OpenShift version is earlier than 3.10 AND the router component is deployed and processing route configurations.

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 data3.10
Upgrade OpenShift routing to version 3.10 or later which contains proper input validation fixes to prevent this denial of service condition.
