CVE-2020-27284
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 · uneditedTPEditor (v1.98 and prior) is vulnerable to two out-of-bounds write instances in the way it processes project files, allowing an attacker to craft a special project file that may permit arbitrary code execution.
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 confidenceTPEditor versions 1.98 and prior contain two out-of-bounds write vulnerabilities when parsing project files. By crafting a malicious project file with specially crafted data, an attacker can trigger memory corruption that leads to arbitrary code execution with the privileges of the running user.

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.
-
Check TPEditor versionOpen TPEditor and navigate to Help > About, or right-click the executable and view Properties > Details to see the version numberAffected if The displayed version is 1.98 or lower
-
Locate TPEditor executableSearch for tpeditor.exe in common installation paths such as C:\Program Files\Delta TPEditor\ or C:\Program Files (x86)\Delta TPEditor\Affected if TPEditor executable exists on the system at any version
-
Verify project file handling is enabledTPEditor by default opens and parses .tpe project files - confirm the application has functionality to open or import project files (File > Open or File > Import)Affected if Project file open/import functionality is present and accessible
-
Check for recent project file activityReview TPEditor recent files list or check for .tpe files in user documents or recent locationsAffected if User has opened or may open project files from potentially untrusted sources
A user is affected if TPEditor version 1.98 or lower is installed and the software is used to open project files, since the vulnerability triggers during parsing of malicious project files.
Generated from the published advisory. Verify against your own configuration.
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 dataUpdate TPEditor to a patched version beyond v1.98. Until then, do not open project files from untrusted sources.
