CVE-2023-43818
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 buffer overflow exists in Delta Electronics Delta Industrial Automation DOPSoft. 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 · moderate confidenceA buffer overflow vulnerability exists in Delta Electronics Delta Industrial Automation DOPSoft software. The vulnerability can be exploited by a remote, unauthenticated attacker through a specially crafted DPS project file. Successful exploitation allows the attacker to achieve remote code execution on the targeted system.

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 the system for 'DOPSoft' folder or executable. Common paths include C:\Program Files\Delta\DOPSoft or C:\Program Files (x86)\Delta\DOPSoft. Check Program Files directories and any custom installation paths.Affected if DOPSoft software is found on the system
-
Identify installed DOPSoft versionRight-click on the DOPSoft.exe file, select Properties, then navigate to the Details tab to view the Product Version. Alternatively, check the version info in the application's About dialog if accessible.Affected if The version number falls within the range 2.00.00.00 to 2.00.07.04 inclusive
-
Verify DPS file association or recent file activityCheck if .DPS files are associated with DOPSoft by looking at file associations in Windows Registry under HKCR\.dps, or by reviewing recent documents opened by the application.Affected if DPS file handling is enabled or DPS files have been opened recently
A user is affected if DOPSoft version 2.00.00.00 through 2.00.07.04 is installed and the system handles DPS project files.

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 DPS files from untrusted or unknown sources. Apply vendor patches when available and ensure industrial systems are properly segmented from untrusted networks.
