CVE-2023-0123
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 · uneditedDelta Electronics DOPSoft versions 4.00.16.22 and prior are vulnerable to a stack-based buffer overflow, which could allow an attacker to remotely execute arbitrary code when a malformed file is introduced to the software.
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 confidenceDelta Electronics DOPSoft versions 4.00.16.22 and prior contain a stack-based buffer overflow vulnerability that can be triggered by processing malformed files, potentially allowing remote arbitrary 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 installationSearch for DOPSoft in the system: check Program Files (e.g., C:\Program Files\Delta Industrial Automation\DOPSoft) or Program Files (x86), and look for DOPSoft.exe or related executable files.Affected if DOPSoft software is found on the system
-
Identify installed versionRight-click the DOPSoft executable, select Properties, then go to the Details tab to view the File Version or Product Version. Alternatively, check any version information in the software's About or Help menu.Affected if The displayed version is 4.00.16.22 or any version prior to it (e.g., 4.00.16.21, 4.00.15.x, earlier)
-
Confirm vulnerability applicabilityReview the software's use case: determine if the installation is used to open or process project files (.dop, .dopx, or related file formats) from external or untrusted sources.Affected if The vulnerable version (4.00.16.22 or prior) is installed AND the software is used to process project files from external or untrusted sources
A system is affected if Delta Electronics DOPSoft version 4.00.16.22 or earlier is installed and is used to process project files, as the stack-based buffer overflow triggers when malformed files are opened.

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.
dbcve · scoped4.00.16.22
Update DOPSoft to a version newer than 4.00.16.22, and implement input validation or network segmentation to limit exposure to untrusted files.
DOPSoft version 4.00.16.22 or later
- 1. Identify the current version of DOPSoft installed by opening the application and checking 'Help' > 'About DOPSoft'
- 2. Navigate to the official Delta Electronics download page for DOPSoft software
- 3. Download DOPSoft version 4.00.16.22 or the latest available version
- 4. Close any running instances of DOPSoft before installation
- 5. Run the installer with administrator privileges
- 6. Follow the installation wizard prompts to complete the upgrade
- 7. After installation, verify the new version by checking 'Help' > 'About DOPSoft'
- 8. Test that existing projects open correctly in the updated version
