CVE-2022-21137
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 · uneditedOmron CX-One Versions 4.60 and prior are vulnerable to a stack-based buffer overflow while processing specific project files, which may allow an attacker to execute arbitrary code.
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 confidenceOmron CX-One versions 4.60 and prior contain a stack-based buffer overflow vulnerability when parsing specific project files. The overflow occurs due to insufficient bounds checking during file processing, allowing an attacker to overwrite stack memory and potentially execute arbitrary code by crafting malicious project files.

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.
-
Verify Omron CX-One installationCheck Program Files for Omron CX-One directory (typically at C:\Program Files\Omron\CX-One or C:\Program Files (x86)\Omron\CX-One) and look for CX-Programmer, CX-Integrator, or other CX-One component foldersAffected if CX-One software is present on the system
-
Identify installed CX-One versionLocate the CX-One version information - check the installer log, or right-click the main executable (e.g., CX-Programmer.exe), select Properties, and view the Version tab for the product versionAffected if The installed version number is 4.60 or lower, or if no version can be confirmed and the software is older
-
Confirm project file handling is in useIdentify whether the system contains or processes CX-One project files (.cxp, .cxi, .cxt, or other CX project file extensions) which trigger the vulnerable parsing functionAffected if Project files from untrusted sources are opened or processed by CX-One on this system
-
Check for recent CX-One execution or file accessReview Windows Event Logs or system audit logs for recent CX-One application execution and any associated project file access eventsAffected if CX-One has been recently used to open project files, indicating the vulnerable parsing code path could have been triggered
The system is affected if Omron CX-One version 4.60 or prior is installed and the software is used to process project files, as the buffer overflow occurs during project file parsing.

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 dataApply vendor-supplied patches or updates to CX-One version 4.60 or later. If patches are unavailable, restrict access to project files from untrusted sources and implement network segmentation for systems running CX-One.
