CVE-2015-1834
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 path traversal vulnerability was identified in the Cloud Foundry component Cloud Controller that affects cf-release versions prior to v208 and Pivotal Cloud Foundry Elastic Runtime versions prior to 1.4.2. Path traversal is the 'outbreak' of a given directory structure through relative file paths in the user input. It aims at accessing files and directories that are stored outside the web root folder, for disallowed reading or even executing arbitrary system commands. An attacker could use a certain parameter of the file path for instance to inject '../' sequences in order to navigate through the file system. In this particular case a remote authenticated attacker can exploit the identified vulnerability in order to upload arbitrary files to the server running a Cloud Controller instance - outside the isolated application container.
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 confidenceA path traversal vulnerability in the Cloud Foundry Cloud Controller allows authenticated remote attackers to upload arbitrary files outside the isolated application container by manipulating file path parameters with '../' sequences. The vulnerability affects cf-release versions prior to v208 and Pivotal Cloud Foundry Elastic Runtime prior to 1.4.2.

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 for presence of Cloud Foundry Cloud Controller component in your environment by reviewing deployment manifests or running 'cf curl /v2/info' against the API endpointAffected if The Cloud Controller API is accessible and part of your deployment
-
Determine cf-release versionRun 'bosh releases' or check the deployment manifest to identify the installed cf-release version numberAffected if The installed cf-release version is 207 or earlier
-
Determine Elastic Runtime versionRun 'cf curl /v2/info' and check the 'api_version' field, or check the Pivotal Ops Manager for the Elastic Runtime versionAffected if The installed Elastic Runtime version is 1.4.1 or earlier
-
Verify authenticated file upload accessConfirm that the Cloud Controller API is accessible to users who can push applications, which enables the file upload functionality where the path traversal flaw existsAffected if Users with push permissions can access the Cloud Controller API
Your environment is affected if Cloud Foundry Cloud Controller is deployed with cf-release v207 or earlier, or Elastic Runtime 1.4.1 or earlier, and users have application push permissions.

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 dataUpgrade Cloud Controller to cf-release v208 or later, or Pivotal Cloud Foundry Elastic Runtime 1.4.2 or later, which contain the patch for proper input validation to prevent path traversal.
