CVE-2017-18703
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.

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 confidenceCross-Site Request Forgery (CSRF) vulnerability in multiple NETGEAR router firmware versions. Attackers can trick authenticated users into unknowingly executing unauthorized configuration changes by luring them to malicious websites while logged into the router's web interface.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify your NETGEAR router modelLocate the model number on the device label (usually on the bottom or back of the router) or log into the router web interface and check the status or administration page for the exact model designationAffected if The model is one of: D1500, D500, D6100, D7000, D7800, Ex6100, Ex6150, or Jnr1010
-
Determine the installed firmware versionLog into the router web interface and navigate to the Administration or Firmware Upgrade section to view the current firmware version. The version is typically displayed as a number such as 1.0.0.x or 1.1.0.xAffected if The firmware version displayed is below the patched version for your specific model (D1500/D500: < 1.0.0.25, D6100: < 1.0.0.55, D7000: < 1.0.1.50, D7800: < 1.0.1.28, Ex6100/Ex6150: < 1.0.1.60, Jnr1010: < 1.1.0.46)
-
Confirm the web management interface is accessibleAttempt to access the router web interface by entering the router IP address in a web browser. Verify that the login page loads and accepts authentication credentialsAffected if The web interface is reachable on the local network or remotely, as this is the attack surface where CSRF requests can be sent
You are affected if you own one of the eight listed NETGEAR models and your installed firmware version falls below the threshold specified for that model, with the web interface accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data1.0.0.251.0.0.551.0.1.28
Apply vendor-provided firmware updates for each affected model. If updates are unavailable, consider replacing affected devices or implementing additional network segmentation controls to limit exposure.
