CVE-2023-43819
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 · uneditedA stack based buffer overflow exists in Delta Electronics Delta Industrial Automation DOPSoft when parsing the InitialMacroLen field of a DPS file. A remote, unauthenticated attacker can exploit this vulnerability by enticing a user to open a specially crafted DPS file to achieve remote 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 · high confidenceA stack-based buffer overflow vulnerability exists in Delta Electronics DOPSoft when parsing the InitialMacroLen field within DPS files. By crafting a DPS file with an oversized InitialMacroLen value, an attacker can overflow the stack buffer and achieve remote code execution.

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.
-
Locate DOPSoft installation directorySearch for DOPSoft installation folders, typically found in C:\Program Files\Delta Electronics\DOPSoft or C:\Program Files (x86)\Delta Electronics\DOPSoft. Check Program Files directories or use file explorer search for 'DOPSoft' folder.Affected if DOPSoft folder exists on the system
-
Identify installed DOPSoft versionWithin the DOPSoft installation directory, locate the executable file (usually DOPSoft.exe). Right-click the executable, select Properties, and view the Details tab to find the File Version or Product Version.Affected if Version displayed is between 2.00.00.00 and 2.00.07.04 inclusive
-
Verify DPS file handling capabilityConfirm the installation includes the ability to open .dps project files. Check if .dps file association exists or if the software includes file open/save functionality for DPS files.Affected if DOPSoft can open DPS files and the software is running a vulnerable version
-
Determine exposure to untrusted DPS filesReview system for any DPS files from untrusted or unknown sources. Check download folders, email attachments, or network shares where unverified DPS files may be present.Affected if Users open DPS files from untrusted sources and DOPSoft version is within the affected range
A user is affected if DOPSoft version 2.00.00.00 through 2.00.07.04 is installed and the software is used to open DPS files, particularly those 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 untrusted DPS files from unverified sources. Apply vendor patches when available and consider implementing application sandboxing or network isolation to limit exposure.
