CVE-2017-18784
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 Scripting (XSS) vulnerability in multiple NETGEAR router models' web management interface. The vulnerability allows attackers to inject malicious scripts through the router's HTTP interface, likely due to insufficient input validation in web parameters. Affected routers run firmware versions prior to the specified patched releases.

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 the NETGEAR router modelLook at the device label on the router or access the web management interface and check the status or settings page for the model numberAffected if The router model is one of: D6200, D7000, Jnr1010, Jwnr2010, Pr2000, R6020, R6050, or R6080
-
Determine the current firmware versionLog into the router web interface (typically at 192.168.1.1) and navigate to the Firmware Upgrade or Administration section to view the installed versionAffected if The firmware version is lower than the patched version for your model (D6200: 1.1.00.24, D7000: 1.0.1.52, Jnr1010/Jwnr2010: 1.1.0.44, Pr2000: 1.0.0.20, R6020/R6080: 1.0.0.26, R6050: 1.0.1.12)
-
Verify remote web management is enabledCheck the router settings under Remote Management or Web Management options to see if remote access over HTTP/HTTPS is enabledAffected if Remote web management is enabled and the router is accessible from the internet on HTTP/HTTPS ports
If you own one of the affected NETGEAR router models and your firmware version is below the patched release listed for that model, and the web management interface is accessible (especially remotely), your router is likely affected by this XSS vulnerability.

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 data1.0.0.201.0.0.261.0.1.12
Update affected NETGEAR router firmware to the versions specified in the advisory (e.g., D6200 to 1.1.00.24, R6700v2 to 1.2.0.12). If firmware updates are unavailable, disable remote web management and restrict local access to trusted users.
