CVE-2017-18713
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 an attacker's ability to read arbitrary files. This affects D7800 before 1.0.1.28, R6700 before 1.0.1.36, R6900 before 1.0.1.34, R7500v2 before 1.0.3.20, R7800 before 1.0.2.40, R9000 before 1.0.2.52, WNDR4300v2 before 1.0.0.48, and WNDR4500v3 before 1.0.0.48.
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 confidenceNETGEAR router vulnerability allowing unauthenticated attackers to read arbitrary files from the device filesystem. The flaw likely involves path traversal in a web service component, enabling access to sensitive configuration files, credentials, or other system files on affected D7800, R6700, R6900, R7500v2, R7800, R9000, WNDR4300v2, and WNDR4500v3 devices running 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 router modelLocate the model number on the device label or check via the admin web interface (typically at 192.168.1.1) under a Status or Administration pageAffected if Model is D7800, R6700, R6900, R7500v2, R7800, R9000, WNDR4300v2, or WNDR4500v3
-
Check installed firmware versionAccess the router admin interface and navigate to the Firmware Version or Router Status page, or check NETGEAR support site for your model using the serial numberAffected if Firmware version is below the patched threshold for your model (R7800 < 1.0.2.40, R9000 < 1.0.2.52, Wndr4300 < 1.0.0.48, Wndr4500 < 1.0.0.48, D7800 < 1.0.1.28, R7500 < 1.0.3.20, R6700 < 1.0.1.36, R6900 < 1.0.1.34)
-
Verify web service accessibilityDetermine if the router web interface (HTTP/HTTPS on ports 80 or 443) is accessible from untrusted networks such as the internet or guest Wi-Fi segmentsAffected if The admin web interface is exposed to networks outside your trusted management network, enabling unauthenticated attackers to reach the vulnerable component
You are affected if your router model matches one of the listed models and your current firmware version is below the patched version threshold, especially if the router web interface is accessible from untrusted networks.

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.

Apply available NETGEAR firmware updates for affected models to remediate the arbitrary file read vulnerability. Network segmentation can limit exposure if immediate patching is not feasible.
