CVE-2017-18731
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 incorrect configuration of security settings. This affects R6100 before 1.0.1.16, R7500 before 1.0.0.112, R7500v2 before 1.0.3.20, R7800 before 1.0.2.36, and WNR2000v5 before 1.0.0.58.
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 confidenceCertain NETGEAR router models (R6100, R7500, R7500v2, R7800, WNR2000v5) contain an incorrect security configuration in their firmware. The specific misconfiguration allows unauthorized access or privilege escalation, as indicated by the high CVSS score of 8.8.

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 modelLocate the model number label on the router device (usually on the bottom or back of the unit) or access the router web interface and check the status or admin page for the exact model designationAffected if The model is not one of: R6100, R7500, R7500v2, R7800, or WNR2000v5 - then this CVE does not apply
-
Check firmware versionAccess the router web administration interface (typically at 192.168.1.1 or 192.168.0.1), log in with admin credentials, and navigate to the Router Status or Administration > Firmware Upgrade page to view the current firmware versionAffected if Unable to determine the firmware version from the router interface
-
Compare installed version to affected rangesCompare your installed firmware version against these ranges: R6100 < 1.0.1.16, R7500 < 1.0.0.112 or < 1.0.3.20, R7500v2 < 1.0.3.20, R7800 < 1.0.2.36, WNR2000v5 < 1.0.0.58Affected if Your installed firmware version falls below any of the listed version thresholds for your specific model
You are affected if you own an R6100, R7500, R7500v2, R7800, or WNR2000v5 Netgear router running firmware version lower than the specified threshold for your model.

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 data1.0.0.581.0.0.1121.0.1.16
Update NETGEAR router firmware to the specified minimum versions (R6100: 1.0.1.16, R7500: 1.0.0.112, R7500v2: 1.0.3.20, R7800: 1.0.2.36, WNR2000v5: 1.0.0.58) or later to remediate the security misconfiguration.
