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 on Actiontec GT784WN modems with firmware before NCS01-1.0.13 allows remote attackers to hijack the authentication or intranet connectivity of arbitrary users.

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

Cross-site request forgery (CSRF) vulnerability in Actiontec GT784WN modem firmware versions prior to NCS01-1.0.13 allows remote attackers to craft malicious requests that execute actions in the context of authenticated users, enabling hijacking of web session authentication or intranet connectivity.

MitigationUpgrade Actiontec GT784WN firmware to version NCS01-1.0.13 or later to address the CSRF vulnerability; avoid browsing untrusted sites while authenticated to the modem admin interface as a compensating control.

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 router's web interface (typically at 192.168.0.1) and check the status or device info page to confirm the model is Actiontec GT784WN
    Affected if The device is an Actiontec GT784WN modem
  2. Check firmware version
    In the web admin interface, navigate to the status, system info, or firmware upgrade page to locate the firmware version number
    Affected if Firmware version is 1.0.12 or earlier (versions prior to NCS01-1.0.13)
  3. Verify web management interface is enabled
    Confirm that the router's web-based administrative interface is accessible, typically on port 80 or 443
    Affected if The web admin interface is enabled and reachable on the local network

The device is affected if it is an Actiontec GT784WN running firmware version 1.0.12 or earlier and has the web management interface enabled.
