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
If Security Hardening guide rules are not followed, then Nokia WaveLite products allow a local user to create new users with administrative privileges by manipulating a web request. This affects (for example) WaveLite Metro 200 and Fan, WaveLite Metro 200 OPS and Fans, WaveLite Metro 200 and F2B fans, WaveLite Metro 200 OPS and F2B fans, WaveLite Metro 200 NE and F2B fans, and WaveLite Metro 200 NE OPS and F2B fans.

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

Local authenticated users can manipulate web requests on Nokia WaveLite Metro 200 devices to create new administrative users when security hardening guidelines are not followed, enabling privilege escalation from standard user to administrator.

MitigationApply Nokia's Security Hardening guide rules to properly configure authentication and authorization controls on affected WaveLite devices to prevent unauthorized privilege escalation.

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. Verify firmware version
    Access the device's web management interface or use SNMP to retrieve the firmware version. Look for a version string such as r2.1.0, r2.0.x, or earlier. Compare this version against the affected range.
    Affected if The firmware version is r2.1.0 or any version earlier than r2.1.1
  2. Confirm web management interface is enabled
    Attempt to access the device's web interface on the standard HTTP/HTTPS ports (typically 80 or 443). Check the device configuration to see if the web-based management feature is turned on.
    Affected if The web management interface is accessible and enabled on the device
  3. Identify user account privileges
    Log into the web interface with a standard (non-administrator) user account. Navigate to the user management or administration section to see if standard users have the ability to add, modify, or delete user accounts.
    Affected if Standard (non-privileged) user accounts can access functions to create or modify user accounts, including administrative-level accounts
  4. Check for security hardening configuration
    Review the device's security settings for authentication and authorization controls. Look for configuration options related to user role permissions, access control lists, or privilege escalation protections.
    Affected if Security hardening guidelines have not been applied, or authentication/authorization controls allow standard users to elevate privileges to administrator level

A user is affected if the device runs firmware version r2.1.0 or earlier, has the web management interface enabled, and allows standard users to create or modify administrative accounts without proper security hardening applied.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Nokia's Security Hardening guide rules to properly configure authentication and authorization controls on affected WaveLite devices to prevent unauthorized privilege escalation.

Recommended fix Moderate confidence

r2.1.1

  1. Identify the specific WaveLite Metro 200 variant (Metro 200, Metro 200 OPS, Metro 200 NE, or Metro 200 NE OPS) and fan type (Fan, Fans, or F2B fans) currently deployed
  2. Access the device management interface through the web console
  3. Navigate to the firmware management or system settings section
  4. Download the firmware version r2.1.1 or later from the official Nokia support portal
  5. Upload and apply the r2.1.1 firmware to the device
  6. After firmware upgrade, verify the new firmware version is installed
  7. If the web request manipulation vulnerability persists, ensure security hardening guide rules are applied per Nokia documentation
Caveat Firmware upgrades may cause temporary service interruption; ensure backup configuration is saved before upgrading and plan for appropriate maintenance window

Generated from the published advisory — verify against the referenced sources before acting.
