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.
-
Verify Pivotal CRM installationCheck the Windows registry under HKLM\SOFTWARE\Pivotal\Pivotal CRM for the Version value, or look for Pivotal CRM installation directories (typically in C:\Program Files\Pivotal\ or C:\Program Files (x86)\Pivotal\) and locate the main executable or installer informationAffected if The installed version matches 6.6.04.08 or falls within an unpatched version range relative to 6.6.04.08
-
Locate vulnerable DLL componentsSearch for Pivotal.Core.Common.dll and Pivotal.Engine.Client.Services.Conversion.dll in the Pivotal CRM installation directory (commonly in bin or bin\Core subfolders). Right-click each DLL, select Properties, and check the File Version in the Details tabAffected if Both DLLs exist and their file versions match the vulnerable release 6.6.04.08 or are earlier unpatched versions
-
Confirm web/application exposureReview IIS or the hosting web server configuration for Pivotal CRM sites. Check if the CRM application is bound to a public or internal IP address and accessible over HTTP/HTTPS from network endpoints. Run 'netsh http show urlacl' to list reserved URLs, and inspect web.config files for allowed endpointsAffected if The Pivotal CRM application is accessible from the network without proper authentication restrictions or network segmentation
-
Check for existing patches or updatesExamine the Pivotal CRM installation for any installed updates by checking Add/Remove Programs for recent updates, or look in the installation directory for patch readme files or version info in the bin folder that indicate a version higher than 6.6.04.08Affected if No subsequent version or patch above 6.6.04.08 is installed, meaning the vulnerable DLL versions remain in place
A user is affected if Pivotal CRM version 6.6.04.08 is installed with the vulnerable DLL components (Pivotal.Core.Common.dll and Pivotal.Engine.Client.Services.Conversion.dll) still present and the application is network-accessible.

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 dataApply available patches from the vendor; if no patch exists, implement network segmentation and restrict access to the CRM application to reduce the attack surface until a fix is available.
