CVE-2022-43508
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 · uneditedUse-after free vulnerability exists in CX-Programmer v.9.77 and earlier, which may lead to information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file.
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 confidenceUse-after-free vulnerability in Omron CX-Programmer versions 9.77 and earlier allows remote code execution or information disclosure via specially crafted CXP files. The vulnerability occurs when the software handles memory improperly while parsing CXP project files, leading to freed memory being accessed.

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 checksWork through these to decide whether this CVE applies to you.
-
Check CX-Programmer versionOpen Windows Programs and Features (appwiz.cpl), find 'Omron CX-Programmer' in the list, and note the version number shown in the Version column. Alternatively, right-click on the CX-Programmer executable (usually in C:\Program Files\Omron\CX-Programmer\ or similar location) and select Properties to view the File Version.Affected if The displayed version is 9.77 or lower (for example, 9.77, 9.76, 9.75, etc.)
-
Confirm CXP file handling is possibleCheck if the CX-Programmer installation includes the ability to open .CXP project files. This is the default file format for CX-Programmer projects.Affected if The software can open or import CXP files, which is the standard functionality of CX-Programmer.
-
Identify active project filesSearch for .CXP files on the system by opening File Explorer and searching for '*.cxp' in user folders or project directories.Affected if There are CXP project files present that could potentially be opened with the vulnerable software version.
You are affected if CX-Programmer version 9.77 or lower is installed and you use it to handle CXP project files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate CX-Programmer to a version newer than 9.77, and avoid opening untrusted CXP files from unknown or unverified sources.
Version newer than 9.77 (contact Omron for the exact fixed release)
- 1. Back up all existing CX-Programmer projects (.cxp files) before making any changes
- 2. Check the current installed version of CX-Programmer via Help > About CX-Programmer
- 3. Obtain the latest version of CX-Programmer from the official Omron website or authorized distributors
- 4. Uninstall the current CX-Programmer installation
- 5. Install the updated version that addresses the use-after-free vulnerability
- 6. Verify the new version by checking Help > About CX-Programmer
- 7. Test that existing projects open correctly in the new version
- 8. Do not open untrusted or specially crafted CXP files from untrusted sources
