CVE-2020-26912
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 CSRF. This affects D6200 before 1.1.00.38, D7000 before 1.0.1.78, JR6150 before 1.0.1.24, R6020 before 1.0.0.42, R6050 before 1.0.1.24, R6080 before 1.0.0.42, R6120 before 1.0.0.66, R6220 before 1.1.0.100, R6260 before 1.1.0.64, R6700v2 before 1.2.0.62, R6800 before 1.2.0.62, R6900v2 before 1.2.0.62, R7450 before 1.2.0.62, and WNR2020 before 1.1.0.62.
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 confidenceMultiple NETGEAR router models (D6200, D7000, JR6150, R6020, R6050, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, WNR2020) are vulnerable to Cross-Site Request Forgery (CSRF) in their web management interface. An attacker could craft malicious links that, when clicked by an authenticated administrator, execute unintended configuration changes on the router.

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 router physical label or log into the web management interface and check the status or administration pageAffected if The model is D6200, D7000, JR6150, R6020, R6050, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, or WNR2020
-
Check firmware versionLog into the web management interface (typically at 192.168.1.1) and navigate to the Administration or Router Status page to view the current firmware versionAffected if The installed firmware version is below the fixed version for your model (D6200: 1.1.00.38, D7000: 1.0.1.78, JR6150/R6050: 1.0.1.24, R6020/R6080: 1.0.0.42, R6120: 1.0.0.66, R6220: 1.1.0.100, R6260: 1.1.0.64, R6700v2/R6800/R6900v2/R7450: 1.2.0.62, WNR2020: 1.1.0.62)
-
Confirm web management interface accessibilityAttempt to access the router web interface from a browser on a device connected to the networkAffected if The web management interface is reachable (CSRF attacks require the interface to be accessible to the attacker's malicious page)
You are affected if your NETGEAR router model matches one of the affected models AND your current firmware version is below the fixed version for that model AND the web management interface is accessible on your network.
