CVE-2022-25234
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 · uneditedOut-of-bounds write vulnerability in CX-Programmer v9.76.1 and earlier which is a part of CX-One (v4.60) suite allows an attacker to cause information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file. This vulnerability is different from CVE-2022-21124.
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 confidenceAn out-of-bounds write vulnerability exists in CX-Programmer v9.76.1 and earlier when parsing specially crafted CXP files. The vulnerability allows an attacker to trigger the out-of-bounds write condition, potentially leading to information disclosure or arbitrary code execution through heap corruption or similar memory manipulation.

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 if CX-Programmer is installedCheck the Windows Programs and Features list, or search for CX-Programmer in the start menu, or look for installation directories such as C:\Program Files\Omron\CX-ProgrammerAffected if CX-Programmer is present on the system
-
Determine the installed CX-Programmer versionRight-click on the CX-Programmer shortcut, select Properties, and check the version information in the Details tab, or open CX-Programmer and go to Help > About CX-Programmer to view the exact version numberAffected if The displayed version is 9.76.1 or earlier, or any version lower than 9.77
-
Verify the parsing component is in useThis vulnerability is triggered when CX-Programmer parses CXP project files - this is a core function of the software and occurs automatically when opening such filesAffected if The software is capable of opening and parsing CXP files (which is default functionality)
A user is affected if CX-Programmer version 9.76.1 or earlier (any version below 9.77) is installed on their system.

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 · scoped9.77
Users should avoid opening CXP files from untrusted sources and should update to a patched version of CX-Programmer/CX-One once available from Omron.
CX-Programmer 9.77 or later (as part of CX-One v4.60 or later)
- Verify current CX-Programmer version by opening CX-Programmer and navigating to Help > About CX-Programmer
- Download CX-Programmer version 9.77 or later from the official Omron website or through the CX-One suite update
- Close CX-Programmer if currently open
- Run the installer/updated CX-One suite to install the fixed version
- Restart CX-Programmer and confirm the version is 9.77 or later by checking Help > About
