CVE-2017-18775
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 · uneditedCertain NETGEAR devices are affected by CSRF. This affects R6100 before 1.0.1.12, R7500 before 1.0.0.108, WNDR3700v4 before 1.0.2.86, WNDR4300v1 before 1.0.2.88, WNDR4300v2 before 1.0.0.48, WNDR4500v3 before 1.0.0.48, and WNR2000v5 before 1.0.0.42.
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 NETGEAR router firmware allows remote attackers to trick authenticated users into performing unintended administrative actions on the affected devices (R6100, R7500, WNDR3700v4, WNDR4300v1/v2, WNDR4500v3, WNR2000v5) by leveraging insufficient CSRF protection mechanisms in the web management interface.

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 router modelLog into the router web management interface (typically at 192.168.1.1) and navigate to Router Status or Administration > Router Information to identify the exact model numberAffected if Model is R6100, R7500, WNDR3700v4, WNDR4300v1, WNDR4300v2, WNDR4500v3, or WNR2000v5
-
Check installed firmware versionIn the router web interface, go to Router Status or Administration > Firmware Upgrade to view the current firmware version installed on the deviceAffected if Firmware version is below the patched version for your model (R6100: <1.0.1.12, R7500: <1.0.0.108, WNDR3700v4: <1.0.2.86, WNDR4300v1: <1.0.2.88, WNDR4300v2: <1.0.0.48, WNDR4500v3: <1.0.0.48, WNR2000v5: <1.0.0.42)
-
Confirm web management interface is accessibleVerify that the router web administration interface is reachable on the local network (default 192.168.1.1)Affected if The web management interface is enabled and accessible to untrusted networks or users
Your router is affected if it is one of the listed models AND running a firmware version lower than the patched version, and the web interface is accessible to potentially malicious sites or users.

From vendor data1.0.0.421.0.0.481.0.0.108
Update router firmware to the patched versions specified (R6100: 1.0.1.12, R7500: 1.0.0.108, WNDR3700v4: 1.0.2.86, WNDR4300v1: 1.0.2.88, WNDR4300v2: 1.0.0.48, WNDR4500v3: 1.0.0.48, WNR2000v5: 1.0.0.42). If updates are unavailable, restrict administrative access to trusted networks only and monitor for anomalous requests.
