CVE-2023-43815
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 vulnerability exists in Delta Electronics Delta Industrial Automation DOPSoft version 2 when parsing the wScreenDESCTextLen field of a DPS file. An anonymous attacker can exploit this vulnerability by enticing a user to open a specially crafted DPS file to achieve 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 DOPSoft version 2 when parsing the wScreenDESCTextLen field of DPS project files. An attacker can craft a malicious DPS file with an oversized wScreenDESCTextLen value to overflow a buffer and achieve arbitrary code execution on the victim's machine.

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 installationSearch for DOPSoft executable (typically DOPSoft.exe) in common program directories such as C:\Program Files\Delta Electronics\DOPSoft or C:\Program Files (x86)\Delta Electronics\DOPSoftAffected if DOPSoft is found on the system
-
Identify DOPSoft versionRight-click the DOPSoft.exe file, select Properties, and check the Details tab for the File Version or Product Version fieldAffected if The displayed version falls within the range 2.00.00.00 to 2.00.07.04 inclusive
-
Verify DPS file parsing capabilityConfirm that the DOPSoft application is configured to parse DPS project files by examining the application's file association settings or attempting to open a sample .dps fileAffected if The application can open and parse DPS project files
-
Assess DPS file exposureCheck for presence of DPS files from external or untrusted sources in accessible directories, or review email gateways and download folders for incoming DPS attachmentsAffected if The system processes DPS files from unverified or external sources
The environment is affected if DOPSoft version 2.00.00.00 through 2.00.07.04 is installed and the system opens DPS project files, particularly 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 dataUsers should not open untrusted DPS files from unverified sources. Organizations should apply any available vendor patches for DOPSoft and consider application whitelisting as a defense-in-depth measure.
