CVE-2017-18766
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 DST6501 before 1.1.0.6 and WNR2000v2 before 1.2.0.8.
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 confidenceThis is an arbitrary file read vulnerability in NETGEAR DST6501 and WNR2000v2 routers, allowing unauthenticated attackers to read sensitive files on the device filesystem. The vulnerability stems from insufficient input validation in the web interface, likely a path traversal flaw, enabling retrieval of configuration files, credentials, or other system files.

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 modelAccess the router web interface or check the device label to confirm the model is NETGEAR DST6501 or WNR2000v2Affected if Model is not DST6501 or WNR2000v2 (different models are not affected by this specific CVE)
-
Check firmware version on DST6501Log into the router web interface and navigate to the Status or Firmware Upgrade page to view the installed firmware version. Compare against 1.1.0.6Affected if Firmware version is lower than 1.1.0.6 on DST6501
-
Check firmware version on WNR2000v2Log into the router web interface and navigate to the Status or Firmware Upgrade page to view the installed firmware version. Compare against 1.2.0.8Affected if Firmware version is lower than 1.2.0.8 on WNR2000v2
-
Verify web management interface accessibilityAttempt to access the router web interface from an external network location or check the remote management settings under Administration > Remote ManagementAffected if The web management interface is accessible from untrusted networks (the vulnerability allows unauthenticated file read)
-
Confirm remote administration is enabledCheck the router settings for remote administration/enable remote management options. If enabled, the device is exposed to unauthenticated attackersAffected if Remote administration is enabled and the web interface is internet-facing
The device is affected if it is a DST6501 with firmware below 1.1.0.6 or a WNR2000v2 with firmware below 1.2.0.8, and the web management interface is accessible to 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.
From vendor data1.1.0.61.2.0.8
Apply the vendor-supplied firmware updates (DST6501 to 1.1.0.6 or later, WNR2000v2 to 1.2.0.8 or later). If updates are unavailable, restrict web management interface access to trusted networks or disable remote administration.
