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
Echelon SmartServer 1 all versions, SmartServer 2 all versions prior to release 4.11.007, i.LON 100 all versions, and i.LON 600 all versions. An attacker can use the SOAP API to retrieve and change sensitive configuration items such as the usernames and passwords for the Web and FTP servers. This vulnerability does not affect the i.LON 600 product.

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 · high confidence

The vulnerability allows attackers to exploit the SOAP API on Echelon SmartServer devices to retrieve and modify sensitive configuration items including usernames and passwords for Web and FTP servers. This authentication bypass enables full compromise of administrative credentials.

MitigationUpgrade SmartServer 2 to release 4.11.007 or later. For SmartServer 1, i.LON 100, and i.LON 600 (if impacted), restrict network access to the SOAP API, implement strong authentication, and contact the vendor for patches.

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 device model
    Access the device web interface or check the device label to confirm whether it is an Echelon SmartServer 1, SmartServer 2, or I.lon 100. This determines which version range applies.
    Affected if The device is a SmartServer 1, SmartServer 2 (any version), or I.lon 100.
  2. Check the installed firmware version
    Log into the device administrative interface and navigate to the firmware or system information section. For SmartServer 2, compare the version number to 4.11.007. For SmartServer 1 and I.lon 100, note that all versions are affected.
    Affected if SmartServer 2 firmware is below version 4.11.007, or the device is SmartServer 1 or I.lon 100 (any version).
  3. Verify SOAP API accessibility
    Determine if the SOAP API endpoint is reachable from untrusted networks. Attempt a curl or HTTP request to the SOAP service port (typically port 80/443 on the device) and verify whether authentication is required or can be bypassed.
    Affected if The SOAP API is exposed to untrusted networks without proper authentication controls.
  4. Review administrative credentials
    Check the Web and FTP server user accounts in the device configuration. Look for any unexpected usernames, modified passwords, or accounts that were not created by authorized administrators.
    Affected if Unknown or unauthorized administrative accounts exist, or if existing credentials have been altered without authorization.
  5. Check for signs of exploitation
    Review device logs, audit trails, or network traffic logs for suspicious SOAP API requests, particularly those retrieving configuration files, user lists, or credential data.
    Affected if Logs show unauthorized or anomalous SOAP API queries retrieving sensitive configuration data.

A user is affected if they have a SmartServer 1 or I.lon 100 (any firmware), or a SmartServer 2 with firmware below 4.11.007, and the SOAP API is network-accessible.

From vendor data
Upgrade available Upgrade to 4.11.007 or later
Fixed in 4.11.007
Interim mitigation

Upgrade SmartServer 2 to release 4.11.007 or later. For SmartServer 1, i.LON 100, and i.LON 600 (if impacted), restrict network access to the SOAP API, implement strong authentication, and contact the vendor for patches.
