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
Cross-site request forgery (CSRF) vulnerability in WL-330NUL Firmware version prior to 3.0.0.46 allows remote attackers to hijack the authentication of administrators via unspecified vectors.

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

CSRF vulnerability in WL-330NUL wireless access point firmware versions prior to 3.0.0.46 allows remote attackers to trick authenticated administrators into performing unintended actions, potentially hijacking administrative sessions.

MitigationUpgrade WL-330NUL firmware to version 3.0.0.46 or later. Additionally, implement anti-CSRF tokens for administrative functions and consider network segmentation to limit exposure.

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 device model
    Access the device's administrative web interface or check the physical device label to confirm it is an Asus WL-330NUL wireless access point.
    Affected if The device is not an Asus WL-330NUL model.
  2. Check firmware version via admin interface
    Log into the WL-330NUL administrative panel and navigate to the Firmware Upgrade, System Info, or Status page to view the currently installed firmware version.
    Affected if Unable to determine the firmware version from the admin interface.
  3. Compare version to affected range
    Compare the displayed firmware version number to the affected range: versions prior to 3.0.0.46 are vulnerable. Version 3.0.0.46 and later are not affected.
    Affected if The installed firmware version is lower than 3.0.0.46 (for example, 3.0.0.45, 3.0.0.40, etc.).

The device is affected if it is an Asus WL-330NUL running firmware version lower than 3.0.0.46.
