CVE-2021-21450
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 PSD 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 · high confidenceSAP 3D Visual Enterprise Viewer version 9 contains an improper input validation vulnerability in its PSD (Photoshop document) file parsing logic. When a user opens a specially crafted PSD file from an untrusted source, the application crashes due to insufficient validation of malformed or manipulated file data. The application becomes unusable until the user restarts, resulting in temporary denial of service.

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 is installedCheck the installed programs list in Windows Control Panel or use 'wmic product get name,version' command to list installed softwareAffected if The application is not listed in installed programs, indicating it is not present in the environment
-
Verify the installed version is 9Locate the application executable (typically in Program Files/SAP or similar) and check its version properties, or run 'wmic product where "name like '%SAP 3D Visual Enterprise Viewer%'" get version'Affected if The installed version is exactly 9 (the affected version per the CVE)
-
Confirm PSD file parsing capability is availableLaunch the application and attempt to open a PSD file, or check the application's supported file formats documentation or file type associationsAffected if The application can parse or render PSD files (this is a built-in capability of the viewer)
-
Determine if PSD files from untrusted sources are processedReview user workflows or policies to see if the application is used to open PSD files from external or untrusted sources, or check recent file open historyAffected if Users routinely open PSD files from untrusted or unknown sources using the viewer
A user is affected if SAP 3D Visual Enterprise Viewer version 9 is installed AND the PSD file parsing feature is enabled AND users open PSD files from untrusted sources.

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 PSD files from untrusted or unknown sources; wait for and apply the official SAP security patch addressing the input validation flaw in PSD file processing.
