CVE-2016-11057
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 mishandling of repeated URL calls. This affects JNR1010v2 before 2017-01-06, WNR614 before 2017-01-06, WNR618 before 2017-01-06, JWNR2000v5 before 2017-01-06, WNR2020 before 2017-01-06, JWNR2010v5 before 2017-01-06, WNR1000v4 before 2017-01-06, WNR2020v2 before 2017-01-06, R6220 before 2017-01-06, and WNDR3700v5 before 2017-01-06.
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 confidenceThis vulnerability in multiple NETGEAR router models allows attackers to cause denial of service by making repeated URL calls to the device. The mishandling of these repeated requests leads to device malfunction or unresponsiveness. The CVSS 7.5 score indicates a high-severity availability impact via network-exploitable DoS.

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) or check the device label/sticker. Navigate to the Administration or Status page to confirm the exact model number (e.g., Jnr1010, Jwnr2000, R6220, Wndr3700, Wnr1000, Wnr2020, Wnr614).Affected if The model is one of: Jnr1010, Jwnr2000, Jwnr2010, R6220, Wndr3700, Wnr1000, Wnr2020, or Wnr614.
-
Check firmware versionIn the router web interface, go to Administration > Firmware Update or Status page. Record the exact firmware version string displayed (often shown as a date like V1.0.0.10 or a date like 2016-12-15).Affected if The displayed firmware version date is earlier than 2017-01-06.
-
Verify firmware build dateIf the version shows as a date rather than a number, confirm the build date. Compare the firmware date against the threshold date of 2017-01-06. For version strings without dates, check NETGEAR's release notes for your specific model to determine the build date.Affected if The firmware build date is before January 6, 2017.
-
Confirm network exposureDetermine if the router management interface is accessible from the internet or an untrusted network. Check port forwarding rules, WAN-facing IP access, and firewall configurations. Attempt to access the router from an external IP on port 80/443 if applicable.Affected if The router admin interface is exposed to untrusted networks, increasing exploitability.
The router is affected if it is one of the listed models (Jnr1010, Jwnr2000, Jwnr2010, R6220, Wndr3700, Wnr1000, Wnr2020, or Wnr614) AND its firmware version predates the 2017-01-06 release date.

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 data2017-01-06
Update NETGEAR router firmware to a version released on or after 2017-01-06 for the specific model. If firmware updates are unavailable, consider network segmentation to limit exposure and monitor for unusual traffic patterns indicating DoS attempts.
