Frequently Asked Questions
What is CVE-2016-6637?
CVE-2016-6637 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. Multiple cross-site request forgery (CSRF) vulnerabilities in Pivotal Cloud Foundry (PCF) before 242; UAA 2.x before 2.7.4.7, 3.x before 3.3.0.5, and 3.4.x before 3.4.4; UAA BOSH before 11.5 and 12.x
Am I affected?
Check whether your environment runs cloud_foundry_uaa_bosh, cloud_foundry, cloud_foundry_elastic_runtime, cloud_foundry_ops_manager, cloud_foundry_uaa. If you operate any of those, treat yourself as in scope until you have evidence otherwise. A Vulnios scan will identify the exact assets carrying the affected version.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
Watch CISA's Known Exploited Vulnerabilities catalog for CVE-2016-6637. Cross-reference with public exploit databases and your own SIEM/IDS for indicator-of-compromise patterns. Vulnios tracks KEV status automatically and surfaces it on the asset findings view.
How does Vulnios help with this?
Vulnios continuously cross-references your asset inventory against the live CVE feed (NVD, vendor advisories, CISA KEV, and curated OSINT). When a new CVE matches your environment, you get a prioritized finding with the severity, KEV status, exploit-prediction (EPSS), and a direct path to the vendor patch. You can start a free scan from the homepage.
