CVE-2020-26817
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 an user to open manipulated HPGL 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 in its HPGL (Hewlett-Packard Graphics Language) file parser. When a user opens a specially crafted malicious HPGL file from an untrusted source, the parser fails to properly validate the file content, causing a denial of service condition where the application crashes and remains unavailable until restarted.

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 SAP 3D Visual Enterprise Viewer is installedLook for the application in the system program list (Windows: Control Panel > Programs and Features, or search for the executable named SAP3DVisualEnterpriseViewer.exe in Program Files)Affected if The application is present on the system
-
Confirm the installed version is exactly 9Right-click the executable, select Properties, and check the Version information. Alternatively, run the viewer and check Help > About, or run the executable with a version flag if supported.Affected if The version shown is 9 (any subversion such as 9.0, 9.0.0, etc.)
-
Check if HPGL file handling is availableOpen the application and attempt to open a standard HPGL file (.plt or .hpgl extension), or check File > Open dropdown to see if HPGL is listed as a supported file type in the filter.Affected if HPGL files appear in the supported import formats or can be opened by the viewer
A user is affected if SAP 3D Visual Enterprise Viewer version 9 is installed AND HPGL file import/parsing is available as a feature in the application.

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 HPGL files from untrusted or unknown sources. Apply vendor patches when available. Implement file type validation and consider sandboxing the viewer application.
