Summary
Schneider Electric PowerLogic ION9000, ION7400, PM8000, ION8650, ION8800, and legacy ION products use an unencrypted ION protocol for communication between meters and management systems. An attacker on the network path can intercept meter readings, configuration data, and other communications without authentication. The ION9000, ION7400, and PM8000 receive a firmware fix (version 4.0.0 and later) that adds optional Transport Layer Security (TLS) encryption via a secure ION feature. ION8650, ION8800, and legacy ION products will not receive fixes and remain vulnerable to protocol eavesdropping and replay attacks.
What this means
What could happen
An attacker can intercept and read unencrypted communications between PowerLogic meters and monitoring/control systems, potentially exposing energy consumption data and network details, or replay captured traffic to interfere with metering operations.
Who's at risk
Utilities and industrial sites using Schneider Electric PowerLogic power meters for energy monitoring and billing. This affects PowerLogic ION9000, ION7400, PM8000 (which can be patched), and ION8650, ION8800, and legacy ION products (which cannot be patched). Any organization relying on these meters for real-time energy data collection, demand response, or power quality monitoring is at risk.
How it could be exploited
An attacker on the network path between a PowerLogic meter and its management system (historian, SCADA, or cloud platform) can capture the unencrypted ION protocol traffic, extract sensitive data like meter readings and configuration details, or forge packets to alter readings or settings. The attacker must have network-level access (ARP spoofing, network tap, or compromised intermediary).
Prerequisites
- Network access between the PowerLogic meter and any connected management system or historian
- Ability to intercept or sniff network traffic (man-in-the-middle position)
- No authentication is required to exploit the unencrypted protocol

Remediation & Mitigation
0/4
Do now
0/1WORKAROUNDDeploy network encryption for all ION protocol traffic using a VPN or secure tunnel if the device and management system support it, as an interim measure until patches are deployed.
Schedule — requires maintenance window
0/1Patching may require device reboot — plan for process interruption
PowerLogic ION9000
HOTFIXUpgrade PowerLogic ION9000, ION7400, and PM8000 to firmware version 4.0.0 or newer, which includes support for secure ION (TLS encryption). Schedule firmware updates during a maintenance window.
Mitigations - no patch available
0/2The following products have reached End of Life with no planned fix: PowerLogic ION8650 All Versions, PowerLogic ION8800 All Versions, Legacy ION products All Versions. Apply the following compensating controls:
HARDENINGFor PowerLogic ION8650, ION8800, and legacy ION products with no vendor fix available, implement network segmentation to isolate meters on a dedicated VLAN. Restrict management traffic to only authorized engineering workstations and historian servers using firewall rules and access control lists.
HARDENINGReview and audit all systems with access to PowerLogic meter data streams. Ensure management software and historians are on a separate, protected network segment with strict ingress/egress controls.
