Summary
EcoStruxure Power SCADA Anywhere is an on-premises software that provides remote web browser access to the EcoStruxure Power Operation HMI client. A vulnerability exists that could allow an authenticated user to escape the application context and execute arbitrary OS commands on the underlying system. This occurs due to insufficient privilege separation between the web application and the host operating system (CWE-668). The vulnerability affects versions 2020, 2021, 2022 and potentially later versions. No vendor patch is currently available; Schneider Electric recommends implementing network isolation, access controls, and physical security measures as compensating controls.
What this means
What could happen
An authenticated user with legitimate access to EcoStruxure Power SCADA Anywhere could escape the application sandbox and execute arbitrary commands on the underlying operating system, potentially allowing them to modify system configurations, access other applications, or disrupt the HMI's ability to monitor and control power infrastructure.
Who's at risk
Energy sector operators and manufacturing facilities using EcoStruxure Power SCADA Anywhere (2020, 2021, 2022 and later versions) for remote monitoring and control of power distribution and electrical infrastructure should implement compensating security controls immediately. This includes power utilities, data centers, industrial plants, and any organization relying on this HMI for critical power operations monitoring.
How it could be exploited
An attacker with valid credentials to the EcoStruxure Power SCADA Anywhere web interface can exploit a privilege escalation flaw to break out of the application context and gain command-line access to the host OS. From there, they can execute arbitrary OS commands with the privileges of the application's user account.
Prerequisites
- Valid user credentials for EcoStruxure Power SCADA Anywhere web interface
- Network access to the web application (typically on internal network or via VPN)
- The vulnerable version of EcoStruxure Power SCADA Anywhere (2020, 2021, 2022, or later) must be deployed and running

Remediation & Mitigation
0/6
Schedule — requires maintenance window
0/4Patching may require device reboot — plan for process interruption
HARDENINGImplement strict access controls: enforce strong authentication for all user accounts accessing the web interface and regularly audit access logs for suspicious activity
HARDENINGUse a Virtual Private Network (VPN) for all remote access to the system; ensure VPN is configured with current security standards and regularly updated
HARDENINGImplement physical security controls: restrict physical access to the server hosting EcoStruxure Power SCADA Anywhere to authorized personnel only and keep the system locked down
HOTFIXMonitor for vendor updates from Schneider Electric and test in a non-production environment immediately upon availability
Mitigations - no patch available
0/2EcoStruxure™ Power SCADA Anywhere has reached End of Life. The vendor will not release a patch. Apply the following compensating controls:
HARDENINGRestrict network access to EcoStruxure Power SCADA Anywhere: place the system behind a firewall and ensure it is not exposed to the Internet or business network unless required
HARDENINGSegment the control network: isolate the network containing EcoStruxure Power SCADA Anywhere from the business network and the Internet using firewalls and demilitarized zones (DMZs)
