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-119:Improper restriction of operations within the bounds of a memory buffer vulnerability exists in PowerLogic ION7400, PM8000 and ION9000 (All versions prior to V3.0.0), which could cause the meter to reboot or allow for remote code execution.

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 · moderate confidence

A CWE-119 memory buffer vulnerability exists in PowerLogic ION7400, PM8000, and ION9000 power meter firmware versions prior to V3.0.0. The improper restriction of memory operations can lead to buffer overflow, enabling either denial of service (device reboot) or remote code execution on the affected meter devices.

MitigationUpgrade PowerLogic ION7400, PM8000, and ION9000 firmware to version V3.0.0 or later to remediate this vulnerability. Given the critical CVSS score and RCE potential, prioritize patching of externally-accessible meters.

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 the power meter model
    Access the device web interface, serial console, or management software (such as PowerLogic ION Setup) and locate the device model information. Confirm the device is one of: ION7400, PM8000, or ION9000.
    Affected if The device model is NOT ION7400, PM8000, or ION9000 (different models are not affected by this CVE).
  2. Retrieve the installed firmware version
    In the device web interface, go to the firmware or system information page. Alternatively, use the device console or management software to query the firmware version. Look for a version field labeled as Vx.x.x or firmware version.
    Affected if Unable to determine the firmware version from the device interface or management tools.
  3. Compare firmware version against affected range
    Note the installed firmware version (for example: V2.5.0, V2.8.1, V2.9.5). Compare it numerically to version 3.0.0. Any version with a major number less than 3, or major version 3 with minor version 0 and patch 0, is prior to V3.0.0.
    Affected if The installed firmware version is less than V3.0.0 (for example: V2.9.5, V2.8.0, V2.5.2). This means the device is running a vulnerable version.
  4. Verify if network exposure exists
    Review network configuration to determine if the meter is accessible from untrusted networks (DMZ, internet-facing segments, or directly connected to enterprise networks without firewall protection). Check if the device management interface (web UI, ports 80/443) is exposed externally.
    Affected if The vulnerable meter is directly accessible from untrusted networks, increasing the exploit risk for remote code execution.

The device is affected if it is an ION7400, PM8000, or ION9000 power meter running firmware version prior to V3.0.0.

dbcve · scoped
Upgrade available Upgrade to 3.0.0 or later
Fixed in 3.0.0
Interim mitigation

Upgrade PowerLogic ION7400, PM8000, and ION9000 firmware to version V3.0.0 or later to remediate this vulnerability. Given the critical CVSS score and RCE potential, prioritize patching of externally-accessible meters.

Recommended fix High confidence

PowerLogic ION7400/PM8000/ION9000 firmware version 3.0.0

  1. 1. Identify the specific PowerLogic meter model (ION7400, PM8000, or ION9000) in your environment
  2. 2. Check the current firmware version on the device through its web interface or management console
  3. 3. Navigate to the official Schneider Electric download portal (www.se.com) and locate the firmware section for your specific meter model
  4. 4. Download firmware version 3.0.0 or later for your device model
  5. 5. Review Schneider Electric's official firmware upgrade documentation for the specific device before proceeding
  6. 6. Apply the firmware upgrade following Schneider Electric's recommended procedure for the device
  7. 7. After upgrade, verify the firmware version shows 3.0.0 or later and confirm device is operational
