A newly discovered critical vulnerability in Schneider Electric's EcoStruxure platform, tracked as CVE-2025-1960, has raised alarms in the industrial cybersecurity community. This flaw affects the EcoStruxure WebHMI component, potentially allowing remote attackers to execute arbitrary code on vulnerable systems.

Understanding CVE-2025-1960

The vulnerability, rated 9.8 (Critical) on the CVSS v3.1 scale, stems from improper input validation in the WebHMI interface. Attackers can exploit this flaw by sending specially crafted HTTP requests to the target system, leading to:

  • Remote code execution (RCE)
  • Unauthorized access to sensitive data
  • System compromise leading to operational disruption

Affected Products

Schneider Electric has confirmed the following EcoStruxure products are vulnerable:

  • EcoStruxure WebHMI versions 1.5.0 to 2.1.3
  • EcoStruxure Operator Terminal Expert (OTE) versions incorporating WebHMI
  • Certain legacy Modicon M340 PLCs with WebHMI enabled

Exploit Details

Security researchers at Industrial Cybersecurity Labs discovered that:

  1. The vulnerability resides in the authentication bypass mechanism
  2. No valid credentials are required for exploitation
  3. Successful attacks can lead to complete system takeover

Mitigation and Patches
