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 · unedited
Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may allow the pointer to call an incorrect object resulting in an access of resource using incompatible type condition.

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 confidence

A type confusion vulnerability in multiple Omron CX-One suite applications (CX-FLnet, CX-Protocol, CX-Programmer, CX-Server, Network Configurator, Switch Box Utility) allows malformed project files to cause a pointer to reference an incorrect object type, leading to potentially exploitable memory corruption.

MitigationUpdate all affected Omron CX-One applications to versions beyond those listed as vulnerable (4.42 and prior), and avoid opening untrusted project files from unknown sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Omron CX-One applications
    Check Program Files directory for Omron CX-One folders (common paths: C:\Program Files\Omron\CX-One or C:\Program Files (x86)\Omron\CX-One). Also check Windows Programs and Features (Add/Remove Programs) for installed Omron software.
    Affected if Any of these applications are installed: CX-FLnet, CX-Protocol, CX-Programmer, CX-Server, Network Configurator, or Switch Box Utility
  2. Check CX-FLnet version
    Right-click the CX-FLnet executable (typically in C:\Program Files\Omron\CX-One\CX-FLnet\), select Properties, then view the Details tab for version information.
    Affected if Version is 1.00 or lower
  3. Check CX-Protocol version
    Right-click the CX-Protocol executable, select Properties, view Details tab for version.
    Affected if Version is 1.992 or lower
  4. Check CX-Programmer version
    Right-click the CX-Programmer executable, select Properties, view Details tab for version.
    Affected if Version is 9.65 or lower
  5. Check CX-Server version
    Check CX-Server ActiveX Control or CX-Server DCOM settings in Windows Services or via the executable properties.
    Affected if Version is 5.0.22 or lower
  6. Check Network Configurator and Switch Box Utility versions
    Locate each executable in their respective folders under CX-One directory and check Properties for version.
    Affected if Network Configurator is 3.63 or lower, or Switch Box Utility is 1.68 or lower
