CVE-2017-18780
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 · moderate confidencedenial of service vulnerability in multiple NETGEAR router models (D6200, D7000, JNR1010v2, JR6150, JWNR2010v5, PR2000, R6020, R6050, R6080, R6120, R6220, R6700v2, R6800, R6900v2, WNDR3700v5, WNR1000v4, WNR2020, WNR2050) allows attackers to render devices unavailable.

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 interface (typically at 192.168.1.1) and check the status or administration page to confirm the exact model number (e.g., D6200, R6050, R6700v2)Affected if Model matches one of the affected devices: D6200, D7000, JNR1010v2, JR6150, JWNR2010v5, PR2000, R6020, R6050, R6080, R6120, R6220, R6700v2, R6800, R6900v2, WNDR3700v5, WNR1000v4, WNR2020, WNR2050
-
Check installed firmware versionIn the router web interface, navigate to Administration > Firmware Update or Router Status to locate the current firmware version numberAffected if Firmware version is below the threshold for your model (D6200 < 1.1.00.24, D7000 < 1.0.1.52, JNR1010 < 1.1.0.44, JR6150 < 1.0.1.12, JWNR2010 < 1.1.0.44, PR2000 < 1.0.0.20, R6020 < 1.0.0.26, R6050 < 1.0.1.12)
-
Verify WAN accessibilityCheck if the router management interface is exposed to the WAN/internet. Access your public IP from an external network or use an online port scanner to check for open HTTP ports (80, 8080) on your WAN IPAffected if Router admin interface is reachable from the internet on WAN IP
-
Confirm exploitation attempt indicatorsReview router logs (typically under Administration > Logs or Diagnostics) for unusual traffic patterns, repeated connection attempts, or service restarts that may indicate DoS exploitationAffected if Logs show unexplained device reboots, service unavailability, or abnormal traffic from external sources
You are affected if your router model is one of the listed models and your current firmware version is below the specified threshold for that 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 data1.0.0.201.0.0.261.0.1.12
Apply the vendor-provided firmware updates to each affected device model to remediate the vulnerability. If updates are unavailable for specific units, consider network segmentation or device replacement.
