    If customers choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit: Ensure your deployment of PME has followed the cybersecurity hardening guidelines provided with the product. https://product-help.schneider-electric.com/EcoStruxure/Power-Monitoring-Expert-2024/content/2_planning/cybersecurity/cyber-planningrecactions.htm Ensure PME is running in an isolated network. Deploy and configure the Windows firewall to limit access to appropriate network segments. Enforce complex password policies. Review Server Access Permissions: Conduct an audit of all Windows-authenticated users who currently have access to PME. Repeat this audit of your system periodically. Identify all accounts with access rights, especially those with elevated privileges or remote access. Limit access to essential users. Revoke access for any user accounts that are not critical for system functionality or day-to-day operations. Apply the principle of least privilege to ensure users have only the access needed for their role

  • ICSA-25-224-03Schneider Electric EcoStruxure Power Monitoring Expert2025-08-12icsa · cisa_csaf_otUS

    Schneider Electric is aware of multiple vulnerabilities in its EcoStruxure Power Monitoring Expert (PME) and EcoStruxure Power Operation (EPO) and EcoStruxure Power SCADA Operation (PSO) products. EcoStruxure Power Monitoring Expert (PME) is an on-premises software used to help power critical and energy-intensive facilities maximize uptime and operational efficiency. Note: There are some instances of PME being deployed in a Managed Service model. EcoStruxure Power Operation (EPO) and EcoStruxure Power SCADA Operation (PSO) are on-premises software offers that provides a single platform to monitor and control medium and lower power systems. Failure to apply the remediation and/or mitigations provided below may risk deserialization of untrusted data, server-side request forgery and/or path traversal that could result in remote code execution, and/or unauthorized access to sensitive data.
