CVE-2023-43823
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 wTTitleLen 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 · moderate confidenceA stack-based buffer overflow vulnerability exists in Delta Electronics Delta Industrial Automation DOPSoft when parsing the wTTitleLen field within DPS project files. An attacker can exploit this by crafting a malicious DPS file with an oversized wTTitleLen value that overwrites stack memory, enabling remote code execution when a user opens the file.

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.
-
Identify DOPSoft installationCheck for DOPSoft installation in standard locations: C:\Program Files\Delta Electronics\DOPSoft or C:\Program Files (x86)\Delta Electronics\DOPSoft. Look for DOPSoft.exe executable.Affected if DOPSoft is installed on the system
-
Determine installed DOPSoft versionRight-click DOPSoft.exe, select Properties, and check the File Version or Product Version field in the Details tab. Alternatively, use PowerShell: Get-ChildItem -Path 'C:\Program Files*\Delta Electronics\DOPSoft' -Recurse -Filter 'DOPSoft.exe' | ForEach-Object { $_.VersionInfo }Affected if Version falls within 2.00.00.00 to 2.00.07.04 inclusive
-
Verify DPS file handling capabilityConfirm DOPSoft can open .dps project files by checking file associations or attempting to open a sample DPS file if available.Affected if DOPSoft can open DPS files and the vulnerable parsing code is reachable
-
Check for malicious DPS filesInspect any DPS files received from external sources. Look for abnormally large file sizes that may indicate oversized wTTitleLen fields, though manual binary analysis would be required to confirm exploitation.Affected if A specially crafted DPS file with oversized wTTitleLen value is opened in the vulnerable DOPSoft version
A system is affected if Delta Industrial Automation DOPSoft version 2.00.00.00 through 2.00.07.04 is installed and a user opens a malicious DPS file with an oversized wTTitleLen field.

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 dataOrganizations should avoid opening untrusted DPS files in DOPSoft and implement file screening at email gateways to block DPS attachments. Apply vendor patches when released.
