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
CX-Motion-MCH v2.32 and earlier contains an access of uninitialized pointer vulnerability. Having a user to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

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

CX-Motion-MCH v2.32 and earlier contains an access of uninitialized pointer vulnerability. When a user opens a specially crafted project file, the uninitialized pointer can be dereferenced, leading to information disclosure (reading arbitrary memory contents) and potentially arbitrary code execution in the context of the application.

MitigationAvoid opening untrusted or unverified project files in CX-Motion-MCH. Update to a patched version once available from the vendor (Omron). Implement file validation and restrict file handling privileges to limit exploitation impact.

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 CX-Motion-MCH installation
    Locate the CX-Motion-MCH software or firmware on the system or device. Check for the motion control application or associated firmware files.
    Affected if CX-Motion-MCH software or firmware is present on the system
  2. Check firmware version
    Access the firmware version information for the CX-Motion-MCH device or software. This is typically found in the device properties, About screen, or firmware management interface.
    Affected if The firmware version is any version prior to 2.33 (e.g., 2.32, 2.31, etc.)
  3. Verify project file handling is enabled
    Confirm that the CX-Motion-MCH application has the ability to open or import project files. Check if the project file open/import feature is accessible in the software interface.
    Affected if Project file open or import functionality is available and enabled in the application
  4. Assess project file source risk
    Determine whether the system or its users could open project files from untrusted or unverified sources. Check for any file validation or sandboxing controls on project file imports.
    Affected if Users can open project files without validation or from untrusted sources

The environment is affected if CX-Motion-MCH firmware version is below 2.33 and the project file handling feature is available and accessible to users who could load specially crafted files.

Upgrade available Upgrade to 2.33 or later
Fixed in 2.33
Interim mitigation

Avoid opening untrusted or unverified project files in CX-Motion-MCH. Update to a patched version once available from the vendor (Omron). Implement file validation and restrict file handling privileges to limit exploitation impact.

Recommended fix High confidence

Cx Motion MCH Firmware version 2.33

  1. 1. Identify the current version of Cx Motion MCH firmware installed on the device
  2. 2. Download Cx Motion MCH firmware version 2.33 from the official vendor source (Hitachi/Industrial Products)
  3. 3. Review the vendor's official firmware update documentation for specific upgrade procedures
  4. 4. Apply the firmware upgrade following the vendor's recommended process (typically via the CX-Motion software utility or device management interface)
  5. 5. After upgrade, verify that the firmware version is now 2.33 or later
