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-754: Improper Check for Unusual or Exceptional Conditions vulnerability exists that could cause a disruption of communication between the Modicon controller and the engineering software, when an attacker is able to intercept and manipulate specific Modbus response data. Affected Product: EcoStruxure Process Expert (V2021 and prior), EcoStruxure Control Expert (V15.0 SP1 and prior)

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

The vulnerability exists in EcoStruxure Process Expert and Control Expert engineering software from Schneider Electric. When an attacker can intercept and manipulate Modbus response data between the Modicon controller and the engineering software, the improper handling of unusual or exceptional conditions (CWE-754) causes a communication disruption, effectively creating a denial-of-service condition.

MitigationApply vendor patches for EcoStruxure Process Expert (V2021+) and Control Expert (V15.0 SP1+). Additionally, implement network segmentation and use encryption or VPNs for Modbus communications to prevent attackers from intercepting and manipulating response data.

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 installed Schneider Electric engineering software
    Check the system for EcoStruxure Control Expert or EcoStruxure Process Expert installation. Look in Program Files for folders named 'Schneider Electric' or check the Windows Add/Remove Programs list for these product names.
    Affected if Either EcoStruxure Control Expert or EcoStruxure Process Expert is installed
  2. Check Control Expert version
    Open Control Expert, go to Help > About, or locate the version info in the installation directory (typically in a version.txt or about file). Record the full version number.
    Affected if Version is less than 15.0 or exactly 15.0 (15.0.x)
  3. Check Process Expert version
    Open Process Expert, go to Help > About, or locate the version info in the installation directory. Record the full version number or year-based version.
    Affected if Version is 2021 or earlier (year-based versioning)
  4. Verify Modbus communication is in use
    Check the engineering project configuration for Modbus/TCP or Modbus serial communication settings configured to communicate with Modicon controllers. Look in the project tree for Modbus driver configurations.
    Affected if Modbus communication is configured and active between the engineering software and Modicon controllers

A user is affected if they have EcoStruxure Control Expert version 15.0 or earlier, or EcoStruxure Process Expert version 2021 or earlier, AND have Modbus communication configured to interact with Modicon controllers.

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 · scoped
Upgrade available Upgrade to 15.0 or later
Fixed in 15.0
Interim mitigation

Apply vendor patches for EcoStruxure Process Expert (V2021+) and Control Expert (V15.0 SP1+). Additionally, implement network segmentation and use encryption or VPNs for Modbus communications to prevent attackers from intercepting and manipulating response data.

Recommended fix Moderate confidence

EcoStruxure Control Expert > 15.0 SP1; EcoStruxure Process Expert > 2021

  1. 1. Identify the current installed version of EcoStruxure Control Expert or EcoStruxure Process Expert
  2. 2. Navigate to the Schneider Electric download portal at download.schneider-electric.com
  3. 3. Locate and download the latest version of EcoStruxure Control Expert (version greater than 15.0 SP1) or EcoStruxure Process Expert (version greater than 2021)
  4. 4. Review all release notes and installation requirements
  5. 5. Create a complete backup of existing projects and configurations
  6. 6. Execute the upgrade following the official Schneider Electric installation guide
  7. 7. Verify that Modicon controller communication functions normally after upgrade
Caveat Review migration guides for potential project migration requirements and compatibility changes between versions
