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-22: Improper Limitation of a Pathname to a Restricted Directory vulnerability exists in Harmony/HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ), Vijeo Designer Basic (all versions prior to V1.2), or EcoStruxure Machine Expert (all versions prior to V2.0) that could cause a Denial of Service or unauthorized access to system information when connecting to the Harmony HMI over FTP.

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 confidence

A path traversal vulnerability (CWE-22) exists in the FTP server component of Vijeo Designer and EcoStruxure Machine Expert HMI products. An attacker can use '../' sequences in FTP commands to escape the restricted directory and access arbitrary files on the system, causing denial of service or unauthorized information disclosure.

MitigationUpgrade to Vijeo Designer V6.2 SP11 or later, Vijeo Designer Basic V1.2 or later, or EcoStruxure Machine Expert V2.0 or later. If upgrading is not immediately feasible, disable the FTP service or restrict network access to prevent unauthorized connections.

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 if Vijeo Designer or EcoStruxure Machine Expert is installed
    Look for the product in Windows installed programs (Add/Remove Programs), or check common installation directories such as C:\Program Files\Schneider Electric\Vijeo Designer or C:\Program Files\Schneider Electric\EcoStruxure Machine Expert
    Affected if Either product is installed on the system
  2. Determine the installed version of Vijeo Designer
    Check the version information in the program's About or Help menu, or locate the version file in the installation directory (often named version.txt, about.ini, or displayed in the executable properties)
    Affected if Version is less than 6.2.11 for Vijeo Designer, or less than 1.2 for Vijeo Designer Basic
  3. Determine the installed version of EcoStruxure Machine Expert
    Check the version information in the program's About or Help menu, or locate the version file in the installation directory
    Affected if Version is less than 2.0 or exactly equal to 2.0
  4. Check if the FTP server component is enabled
    Examine the product configuration settings or services panel to determine if the FTP server is running or enabled. This may be found in the product's runtime settings, service configuration, or system services list
    Affected if FTP server is enabled or running and the product version falls within the affected ranges

The system is affected if either Vijeo Designer (version < 6.2.11 or < 1.2) or EcoStruxure Machine Expert (version < 2.0 or = 2.0) is installed AND the FTP server component is enabled.
