CVE-2023-22322
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 · uneditedImproper restriction of XML external entity reference (XXE) vulnerability exists in OMRON CX-Motion Pro 1.4.6.013 and earlier. If a user opens a specially crafted project file created by an attacker, sensitive information in the file system where CX-Motion Pro is installed may be disclosed.
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 confidenceThis is an XML External Entity (XXE) injection vulnerability in OMRON CX-Motion Pro software's project file parser. When a user opens a specially crafted malicious project file, the XML parser processes external entity references that allow the attacker to read sensitive files from the local file system where the software is installed, potentially exposing configuration files, credentials, or other system information.

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.
-
Verify OMRON CX-Motion Pro is installedCheck the Windows Add/Remove Programs list, or search for CX-Motion Pro in Program Files directory, or look for the application executable (typically named CX-Motion.exe or similar)Affected if The software is found installed on the system
-
Determine the installed version numberRight-click the CX-Motion Pro executable, select Properties, and check the Details tab for version information; alternatively, open the application and look under Help > About or similar menu optionAffected if The displayed version is below 1.4.6.014
-
Confirm project file handling capabilityAttempt to locate project files (.mpx, .cxp, or similar CX-Motion project file extensions) associated with the software installationAffected if Project files exist and the software can open them, as the vulnerability triggers when parsing these files
-
Assess XML parser exposureReview application logs or documentation for any indication of XML processing behavior when project files are loadedAffected if The application uses an XML-based parser for project files, which is required for the XXE vulnerability to be exploitable
A system is affected if OMRON CX-Motion Pro version 1.4.6.014 or earlier is installed and can open project files using an XML parser, as the XXE vulnerability triggers specifically when parsing malicious project files.

dbcve · scoped1.4.6.014
Update OMRON CX-Motion Pro to version 1.4.6.014 or later. Additionally, disable external entity resolution in XML parsers and train users to only open project files from trusted sources.
1.4.6.014
- Obtain CX-Motion Pro version 1.4.6.014 or later from the official OMRON download source (refer to jvn.jp for official download links)
- Uninstall the current CX-Motion Pro version from the system
- Install the updated version 1.4.6.014
- Verify the installation was successful by checking the software version
- Do not open project files from untrusted or unknown sources to avoid potential XXE attacks
