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
Use after free vulnerability exists in CX-Programmer Ver.9.79 and earlier. By having a user open a specially crafted CXP file, information disclosure and/or arbitrary code execution may occur. This vulnerability is different from CVE-2023-22277 and CVE-2023-22317.

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

Use-after-free vulnerability in CX-Programmer Ver.9.79 and earlier allows remote code execution or information disclosure via specially crafted CXP files. The vulnerability stems from improper memory management during file parsing, leading to a use-after-free condition that can be triggered when a user opens a malicious file.

MitigationUpgrade CX-Programmer to a version newer than 9.79. Until then, exercise caution when opening CXP files from untrusted 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. Locate CX-Programmer installation
    Search for CX-Programmer in the system. Common installation paths include C:\Program Files\Omron\CX-Programmer or C:\Program Files (x86)\Omron\CX-Programmer. Check Start Menu for CX-Programmer shortcuts.
    Affected if CX-Programmer is installed on the system
  2. Identify installed CX-Programmer version
    Open CX-Programmer and navigate to Help > About CX-Programmer, or right-click the executable in the installation folder and select Properties > Details to view the File Version.
    Affected if The displayed version is 9.79 or lower (any version up to and including 9.79)
  3. Confirm vulnerability trigger condition
    Verify that the CX-Programmer installation can open CXP project files. The vulnerability is triggered when a user opens a specially crafted CXP file.
    Affected if Users can open CXP files in the installed version, meaning the parsing code with the use-after-free flaw is active

A user is affected if CX-Programmer version 9.79 or lower is installed and the software can open CXP files, as the vulnerability requires opening a malicious file to trigger the use-after-free condition.
