CVE-2020-16223
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 · uneditedDelta Electronics TPEditor Versions 1.97 and prior. A heap-based buffer overflow may be exploited by processing a specially crafted project file. Successful exploitation of this vulnerability may allow an attacker to read/modify information, execute arbitrary code, and/or crash the application.
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 confidenceDelta Electronics TPEditor versions 1.97 and prior contain a heap-based buffer overflow vulnerability in the project file parsing functionality. Processing a specially crafted malicious project file can trigger the overflow, potentially allowing an attacker to read/modify memory, execute arbitrary code, or cause application crash.

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 TPEditor is installedCheck for TPEditor in installed programs (Windows: Add/Remove Programs or Settings > Apps), or search for tpeditor.exe in common program directories like C:\Program Files\Delta Electronics or C:\Program Files (x86)\Delta ElectronicsAffected if TPEditor is found installed on the system
-
Identify installed TPEditor versionRight-click tpeditor.exe > Properties > Details tab to view File Version, or open TPEditor and check Help > About for the exact version numberAffected if Installed version is 1.97 or any version lower than 1.97
-
Confirm project file associationCheck for .tpe or other TPEditor project file extensions on the system by searching file explorer for common TPEditor extensions, or check TPEditor File > Open dialog for supported file typesAffected if TPEditor project files exist on the system that could be opened by the application
-
Check for recent TPEditor usageReview Windows recent files (AppData\Roaming\Microsoft\Windows\Recent) or TPEditor's internal recent files list if accessible, and check Windows Event Viewer for TPEditor execution eventsAffected if TPEditor has been recently used to open project files
User is affected if TPEditor version 1.97 or lower is installed and the system contains or processes TPEditor project files that could trigger the heap overflow during parsing.

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 dataUntil an official patch is available, avoid opening untrusted project files in TPEditor. Consider running the application in a sandboxed or isolated environment to limit potential impact from successful exploitation.
