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-284:Improper Access Control vulnerability exists in EcoStruxureª and SmartStruxureª Power Monitoring and SCADA Software (see security notification for version information) that could allow for arbitrary code execution on the server when an authorized user access an affected webpage.

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

CWE-284 Improper Access Control vulnerability in EcoStruxure and SmartStruxure Power Monitoring and SCADA Software allows an authenticated/authorized user to achieve arbitrary code execution on the server by accessing a specifically crafted webpage. The vulnerability stems from insufficient access control enforcement on the web interface, enabling authorized users to bypass intended restrictions and execute arbitrary code server-side.

MitigationApply vendor-supplied patches/updates for EcoStruxure and SmartStruxure software. Until patches are available, restrict web interface access to only absolutely necessary authorized users and monitor for suspicious activity.

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 Schneider Electric product
    Locate the product name in the system (check installed programs, application directories, or product documentation). Common locations: C:\Program Files\Schneider Electric\ or the application's About/Help section.
    Affected if The installed product matches EcoStruxure Energy Expert, EcoStruxure Power Monitoring Expert, Power Manager, Powerscada Expert, or Powerscada Operation.
  2. Determine the installed software version
    Access the product's About, Help, or System Information section within the application, or check the Windows Programs and Features list for the exact version number (e.g., 7.0, 8.0, 9.0, 1.1, 1.2, 1.3, 2.0).
    Affected if The version matches any of these: 2.0 (Energy Expert), 7.0/8.0/9.0 (Power Monitoring Expert), 1.1/1.2/1.3 (Power Manager), 8.0 (Powerscada Expert), 9.0 (Powerscada Operation).
  3. Confirm the web interface is enabled
    Check if the web-based monitoring or administration interface is active. Look for web service processes (e.g., IIS, Apache, or the product's embedded web server) listening on ports 80, 443, or custom web ports. Consult the product documentation for the default port.
    Affected if The web interface is accessible and the product version matches the affected versions listed in step 2.
  4. Review web access logs for suspicious requests
    Examine the application's web server logs for unusual parameters, POST requests to unexpected endpoints, or patterns indicating attempts to inject code. Look for logs containing shell commands, script tags, or system path traversals.
    Affected if Logs show unexpected or unauthorized requests that could indicate exploitation attempts, especially from authenticated user sessions.
  5. Verify user access controls and privilege assignments
    Review the application's user management console to confirm which users have access to the web interface. Check for any unexpected accounts or privilege escalations.
    Affected if The web interface is accessible to users beyond those explicitly authorized for administrative functions.

A system is affected if it runs any of the listed products at the specified versions AND has the web interface enabled, allowing authenticated users to potentially bypass access restrictions.
