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
A CWE-94: Improper Control of Generation of Code ('Code Injection') vulnerability exists that could cause execution of malicious code when an unsuspicious user loads a project file from the local filesystem into the HMI.

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

This is a CWE-94 Code Injection vulnerability in HMI (Human-Machine Interface) software. An attacker can embed malicious code within a project file that, when loaded by a user into the HMI application from the local filesystem, results in arbitrary code execution. The attack relies on social engineering to convince an unsuspecting user to open the crafted file.

MitigationImplement strict input validation and sanitization when loading project files, treat all file content as untrusted, and consider sandboxing or restricting the execution environment for project file parsing functionality.

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. Identify the installed product
    Open Windows Control Panel > Programs and Features, or check the program's About/Help menu, and locate either 'Schneider Electric Ecostruxure Operator Terminal Expert' or 'Schneider Electric Pro Face Blue'
    Affected if Either of these products is installed on the system
  2. Check the installed version
    In the Programs and Features list, note the version column for the installed product; or within the application, go to Help > About to view the exact version number
    Affected if The version listed is 3.3 or any version lower than 3.3 (for example, 3.2, 3.1, 3.0, 2.x)
  3. Determine if project file loading is used
    Look for project file types associated with this software (common extensions include .eco, .gp, .gpx, or similar) in the system's recent files, or check the application's recent projects list
    Affected if The software has been used to open or load project files from the local filesystem

The system is affected if either Ecostruxure Operator Terminal Expert or Pro Face Blue version 3.3 or lower is installed and has been used to load project files, because the code injection occurs when a malicious project file is opened.
