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 ION8650, ION8800, ION7650, ION7700/73xx, and ION83xx/84xx/85xx/8600 (see security notifcation for affected versions), which could cause the meter to reboot.

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

CWE-119 buffer overflow vulnerability in Schneider Electric PowerLogic ION series meters (ION8650, ION8800, ION7650, ION7700/73xx, ION83xx/84xx/85xx/8600). The vulnerability is network-exploitable (CVSS AV:N/AC:L/PR:N) with no authentication required, allowing remote attackers to trigger a buffer overflow that causes the meter to reboot.

MitigationApply vendor firmware updates from Schneider Electric security notification to patch the memory boundary validation issue. Since this is an ICS device, updates should be tested in a staging environment before production deployment.

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 Schneider Electric PowerLogic ION meter on the network
    Use network scanning tools (such as nmap, or ICS-specific discovery tools) to locate devices with Schneider Electric vendor identifiers or known ION protocol ports (typically port 502 for Modbus/TCP, or device-specific management ports). Check device hostname, banner, or response to protocol queries for identifiers like ION8650, ION8800, ION7650, ION7700, ION7300, ION8300, or ION8400.
    Affected if A PowerLogic ION series meter (ION8650, ION8800, ION7550/7650, ION7700/7300, ION8300/8400) is found on the network.
  2. Retrieve firmware version from the meter
    Access the device web interface, or query the meter via Modbus/TCP, DNP3, or manufacturer-specific protocol (ION protocol) to retrieve the firmware version field. This is typically found in the device information or system status page via the embedded web server, or through a direct protocol read of identity registers.
    Affected if The retrieved firmware version matches one of the affected product lines and falls below the fixed version for that model.
  3. Compare installed firmware version against affected ranges
    Match the retrieved firmware version to the following thresholds: ION8650 < 4.40.1, ION8800 < 372, ION7550 < 376 or < 416, ION7650 < 376, ION7700/7300/8300/8400 = all versions (any version is affected).
    Affected if The installed version is below the threshold for your specific model, or if the device is ION7700, ION7300, ION8300, or ION8400 (which have no fixed version and are all affected).
  4. Verify network exposure of device management interface
    Confirm whether the meter is directly accessible on the network with its management interface (web UI, Modbus/TCP, or ION protocol port) exposed without firewall segmentation or VPN protection. Check if the device accepts connections from untrusted network segments.
    Affected if The meter management interface is reachable from network segments that contain untrusted or unauthorized users (CVSS vector AV:N indicates network-level attack is possible).

A user is affected if they have any ION7650, ION7700, ION7300, ION8300, or ION8400 meter (all versions), or an ION8650/ION8800/ION7550 meter with firmware below the fixed threshold, and this device is network-accessible to potential attackers.
