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
Out-of-bounds write vulnerability in CX-Programmer v9.76.1 and earlier which is a part of CX-One (v4.60) suite allows an attacker to cause information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file. This vulnerability is different from CVE-2022-25234.

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

Out-of-bounds write vulnerability in CX-Programmer v9.76.1 and earlier allows arbitrary code execution or information disclosure via specially crafted CXP project files. Successful exploitation requires user interaction to open the malicious file.

MitigationAvoid opening CXP files from untrusted sources; apply vendor-supplied updates when available; consider implementing file sandboxing or email gateway filtering for CXP attachments.

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 CX-Programmer is installed
    Check for CX-Programmer in the list of installed programs via Windows Control Panel > Programs and Features, or search for the application in the Start menu
    Affected if CX-Programmer appears in the installed programs list
  2. Identify the installed CX-Programmer version
    Open CX-Programmer, then access the About dialog (typically via Help > About CX-Programmer) to display the exact version number
    Affected if The displayed version is 9.76.1 or earlier, or any version below 9.77
  3. Verify the vulnerable file type association
    Check if .CXP file extension is associated with CX-Programmer by right-clicking any .CXP file and viewing the 'Opens with' property, or checking File > Open dialog in CX-Programmer
    Affected if The .CXP file extension is associated with CX-Programmer and the version is below 9.77
  4. Review recent CX-Programmer activity
    Check Windows Event Viewer for recent CX-Programmer process executions, particularly if the application was launched to open files from external or untrusted sources
    Affected if CX-Programmer version is below 9.77 and the system has been used to open CXP files

A user is affected if CX-Programmer version 9.76.1 or earlier (any version below 9.77) is installed and the software is used to open CXP project files.
