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
Omron CX-Position (versions 2.5.3 and prior) is vulnerable to a use after free memory condition while processing a specific project file, 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 confidence

Omron CX-Position versions 2.5.3 and prior contain a use-after-free vulnerability in the project file processing routine. When parsing a specifically crafted project file, memory is deallocated but still referenced, leading to potential arbitrary code execution. The CVSS 7.8 indicates low attack complexity with no authentication required.

MitigationUpgrade to a patched version of CX-Position when available. Until then, only open project files from trusted sources and consider network segmentation to limit exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Confirm Omron CX-Position is installed
    Look for CX-Position in the list of installed programs on the system (Windows: Programs and Features, or check Program Files directories for Omron CX-Position)
    Affected if Omron CX-Position software is present on the system
  2. Determine the installed version
    Right-click the CX-Position executable (typically named CX-Position.exe or similar), select Properties, and check the Version tab. Alternatively, check the software's About or Help menu for version information
    Affected if The version cannot be determined or is <= 2.5.3
  3. Verify version against affected range
    Compare the installed version number to the affected range: versions 2.5.3 and all prior versions (anything <= 2.5.3)
    Affected if The installed version is 2.5.3 or any version prior to it (e.g., 2.5.2, 2.5.1, 2.0, etc.)
  4. Identify project file processing usage
    Check if CX-Position is used to open project files (.cxp or similar extensions). The vulnerability triggers when parsing these project files
    Affected if The software is used to open project files from untrusted sources

A system is affected if Omron CX-Position version 2.5.3 or any earlier version is installed and the software processes project files.

Upgrade available Upgrade to a release after 2.5.3
Interim mitigation

Upgrade to a patched version of CX-Position when available. Until then, only open project files from trusted sources and consider network segmentation to limit exposure.

Recommended fix Moderate confidence

Omron CX-Position version 2.5.4 or later

  1. 1. Check the current installed version of Omron CX-Position on the affected system
  2. 2. Obtain the latest version of Omron CX-Position from the official Omron vendor website or authorized distributor
  3. 3. Ensure all project files are backed up before upgrading
  4. 4. Uninstall the current version of CX-Position
  5. 5. Install the fixed version of CX-Position (version 2.5.4 or later)
  6. 6. Verify the installation was successful and the version number reflects the update
  7. 7. Test that existing project files open and function correctly in the updated software
