CVE-2023-22277
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 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-2023-22317 and CVE-2023-22314.
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.

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.
-
Identify CX-Programmer installationLocate CX-Programmer on the system via the Windows Start menu, Program Files directory, or by searching for the executable (usually named CX-Programmer.exe or similar). Right-click the application and select 'Properties' to view the version information on the 'Details' tab.Affected if The displayed version number is 9.79 or lower.
-
Compare version to affected rangeCheck the 'File Version' or 'Product Version' field shown in the application properties. CX-Programmer follows a sequential version numbering scheme.Affected if The installed version is 9.79 or any version number lower than 9.79.
-
Determine exposure to CXP file handlingReview whether the system has been used to open .cxp files, which are project files for CX-Programmer. Check recent file access in the Windows Jump List, Recent Documents, or the application's recent files list if available.Affected if The system has opened .cxp files from untrusted or external sources, or users routinely open .cxp files without verification.
A system is affected if CX-Programmer version 9.79 or earlier is installed AND the software is used to open .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 version 9.80 or later; do not open untrusted CXP files until the patch is applied.
CX-Programmer version > 9.79 (latest available version from Omron)
- 1. Navigate to the official Omron website or authorized distributor for CX-Programmer software
