CVE-2022-26419
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-Position (versions 2.5.3 and prior) is vulnerable to multiple stack-based buffer overflow conditions while parsing a specific project file, which may allow an attacker to locally 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-Position versions 2.5.3 and prior contain multiple stack-based buffer overflow vulnerabilities in the project file parsing logic. When parsing a specifically crafted project file, the software fails to properly validate input bounds before copying data to fixed-size stack buffers, allowing an attacker to overwrite return addresses and execute arbitrary code locally.

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.
-
Confirm Omron CX-Position is installedCheck for the application in standard installation paths (typically C:\Program Files\Omron\CX-Position or C:\Program Files (x86)\Omron\CX-Position) or look for the application in Windows Programs and FeaturesAffected if The software is present on the system
-
Identify installed versionRight-click the CX-Position executable (usually named CX-Position.exe), select Properties, and check the File Version field under the Details tab. Alternatively, open the application and check Help > About CX-PositionAffected if The version is 2.5.3 or prior
-
Determine if recent project files were openedReview recent activity logs, check the application's recent files list (File > Recent Files), or examine the modification timestamps of any .zap or project files in the workspace directoryAffected if Untrusted or unusually-named project files were opened recently, especially from unknown sources
-
Check for signs of abnormal process behaviorUse Task Manager or Process Explorer to examine running CX-Position processes for unexpected child processes, unusual memory consumption, or connections to unknown network endpointsAffected if The application exhibits unexpected behavior or spawns unknown processes
The system is affected if Omron CX-Position version 2.5.3 or prior is installed AND untrusted project files may have been opened, warranting further investigation for potential exploitation.

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 dataUpgrade to a version newer than 2.5.3. Avoid opening untrusted project files and implement least-privilege execution for the application until patching is possible.
