CVE-2020-6321
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 · uneditedSAP 3D Visual Enterprise Viewer, version - 9, allows a user to open manipulated U3D file received from untrusted sources which results in crashing of the application and becoming temporarily unavailable until the user restarts the application, this is caused due to Improper Input Validation.
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 · moderate confidenceSAP 3D Visual Enterprise Viewer version 9 contains an improper input validation vulnerability when processing U3D (Universal 3D) files. Opening a manipulated U3D file from an untrusted source triggers the vulnerability, causing the application to crash and become unavailable until the user restarts the application.

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.
-
Confirm SAP 3D Visual Enterprise Viewer installationCheck the installed programs on the system for 'SAP 3D Visual Enterprise Viewer' - look in Add/Remove Programs (Windows) or Application folder (Mac/Linux)Affected if The application is listed as installed on the system
-
Identify the exact version numberRight-click the application executable, select Properties, then look at the Version or Details tab. Alternatively, launch the application and check Help > AboutAffected if The version is listed as exactly version 9
-
Determine if U3D file handling is usedSearch the system for .u3d file associations - check default file locations, recent documents, or search for files with .u3d extension using the file explorer search functionAffected if The system contains or has recently opened .u3d files, indicating the vulnerable parser is in use
-
Check for application crash historyReview Windows Event Viewer under Windows Logs > Application for recent crash events related to '3D Visual Enterprise Viewer', or check for dump files in the application directoryAffected if Recent crash events involving the viewer application are present in the logs
The environment is affected if SAP 3D Visual Enterprise Viewer version 9 is installed AND the system handles or has recently processed U3D files, making the input validation vulnerability potentially triggerable.

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 dataAvoid opening U3D files from untrusted or unknown sources. Apply vendor patches when released by SAP to address the input validation deficiency in the U3D file parser.
