CVE-2016-2169
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 · uneditedCloud Foundry Cloud Controller, capi-release versions prior to 1.0.0 and cf-release versions prior to v237, contain a business logic flaw. An application developer may create an application with a route that conflicts with a platform service route and receive traffic intended for the service.
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 confidenceCloud Foundry Cloud Controller contains a business logic flaw that allows application developers to create routes that conflict with platform service routes. This route conflict vulnerability could enable an attacker to intercept traffic intended for platform services by registering a malicious route that overlaps with service endpoints.

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 Cloud Foundry deploymentCheck if your environment runs Cloud Foundry by querying bosh deployments, checking for capi-release or cf-release components, or accessing the Cloud Controller API endpointAffected if Cloud Foundry is deployed in your environment
-
Check Capi Release versionRun 'bosh releases' or inspect your deployment manifests to determine the installed version of capi-releaseAffected if capi-release version is less than 1.0.0
-
Check Cf Release versionRun 'bosh releases' or inspect your deployment manifests to determine the installed version of cf-releaseAffected if cf-release version is less than 237
-
Verify route creation capabilityConfirm that application developers have access to the Cloud Controller API to create routes (e.g., POST /v2/routes endpoint is accessible and permitted for non-admin users)Affected if Users can register routes through the Cloud Controller API
You are affected if your Cloud Foundry deployment uses capi-release before 1.0.0 or cf-release before version 237, and users have the ability to create routes through the Cloud Controller API, allowing potential route conflicts with platform service endpoints.

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 data1.0.0237
Upgrade Cloud Foundry components to patched versions: capi-release to version 1.0.0 or later, or cf-release to v237 or later. This addresses the route conflict validation logic in the Cloud Controller.
