CVE-2016-9880
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 GemFire broker for Cloud Foundry 1.6.x before 1.6.5 and 1.7.x before 1.7.1 has multiple API endpoints which do not require authentication and could be used to gain access to the cluster managed by the broker.
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 GemFire broker for Cloud Foundry versions 1.6.x before 1.6.5 and 1.7.x before 1.7.1 contains multiple API endpoints that lack authentication controls, allowing unauthenticated attackers to potentially access and control the managed GemFire cluster.

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 the GemFire broker version in Ops ManagerIn the Pivotal Operations Manager UI, navigate to the 'Pivotal GemFire' tile and locate the version number displayed on the tile information panelAffected if The displayed version is 1.6.0 through 1.6.4, or exactly 1.7.0
-
Check the product installation manifestIf you have access to the installation files, open the stemcell or product metadata JSON file for GemFire for PCF and locate the 'product_version' fieldAffected if The version field shows 1.6.0-1.6.4 or 1.7.0
-
Query the Cloud Foundry API for service broker versionRun 'cf service-brokers' to list service brokers, then inspect metadata for the gemfire broker using 'cf service-broker gemfire' or check the API response from /v2/service_brokersAffected if The returned version matches 1.6.0-1.6.4 or 1.7.0
-
Review installation receipts or logsCheck Ops Manager installation logs or the /var/tempest/workspaces/default/tenants/*/installations directory for GemFire installation receipt files that contain version stringsAffected if The receipt shows version 1.6.0-1.6.4 or 1.7.0
You are affected if the GemFire for PCF tile version is 1.6.0 through 1.6.4 or exactly 1.7.0, as these versions contain API endpoints without authentication controls.

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.
dbcve · scoped1.6.5
Upgrade the GemFire broker to version 1.6.5, 1.7.1, or later to implement proper authentication on all API endpoints.
Upgrade to GemFire for Pivotal Cloud Foundry 1.6.5 (for 1.6.x users) or 1.7.1 (for 1.7.x users)
- Identify the current GemFire for Pivotal Cloud Foundry version deployed in your environment
- If running 1.6.x (1.6.0 through 1.6.4), plan upgrade to version 1.6.5
- If running 1.7.0, plan upgrade to version 1.7.1
- Review Pivotal documentation for GemFire for PCF upgrade procedures
- Backup all existing GemFire broker configurations and cluster data
- Execute the upgrade to the appropriate fixed version (1.6.5 or 1.7.1)
- After upgrade, verify that all API endpoints now require authentication
