CVE-2023-0124
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 an out-of-bounds write, 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 · moderate confidenceDelta Electronics DOPSoft versions 4.00.16.22 and prior contains an out-of-bounds write vulnerability in its file parsing functionality. When the software processes a specially crafted malformed file, it writes data beyond allocated memory boundaries, which can be exploited to achieve arbitrary 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 for DOPSoft executable (DOPSoft.exe) in typical installation paths such as C:\Program Files\Delta Industrial Automation\DOPSoft or C:\Program Files (x86)\Delta Industrial Automation\DOPSoft. Also check the program's About or Help menu within the application for the installation path.Affected if DOPSoft.exe is not found on the system, meaning the software is not installed.
-
Check DOPSoft version numberRight-click on the DOPSoft.exe file, select Properties, then go to the Details tab. Note the Product version field. Alternatively, open DOPSoft, click Help > About DOPSoft to display the version dialog.Affected if The displayed version is 4.00.16.22 or any version lower than 4.00.16.22.
-
Verify installed version against vendor recordsCompare your identified version number to the affected range. Versions are formatted as major.minor.build.revision. Confirm whether your version falls below 4.00.16.22.Affected if Your installed version is less than 4.00.16.22, making the file parsing component vulnerable to the out-of-bounds write flaw.
You are affected if DOPSoft is installed and the version number is 4.00.16.22 or any earlier version, since the vulnerability exists in the file parsing functionality of those releases.

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 data4.00.16.22
Update DOPSoft to a version newer than 4.00.16.22 once a vendor patch is available. Until then, avoid opening untrusted or unsolicited files with DOPSoft and apply network segmentation to isolate HMI engineering workstations.
