CVE-2019-20710
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 command injection by an authenticated user. This affects D3600 before 1.0.0.76, D6000 before 1.0.0.76, and XR500 before 2.3.2.32.
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 authenticated command injection vulnerability affecting NETGEAR D3600, D6000, and XR500 routers. An authenticated attacker can execute arbitrary OS commands on the underlying system through this flaw, effectively achieving privilege escalation from authenticated user to full system command execution.

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 admin web interface and check the device information page, or look at the device label/marketing material to confirm the model is XR500, D3600, or D6000Affected if Model is Netgear XR500, D3600, or D6000 and firmware version is below the fixed release
-
Check firmware versionIn the router admin interface, navigate to Administration > Firmware Update or look under the device status/information section to find the currently installed firmware versionAffected if Firmware version is less than 2.3.2.32 for XR500, or less than 1.0.0.76 for D3600/D6000
-
Verify web management interface accessibilityCheck if the router web admin interface is accessible from the WAN/internet side. This is typically found under Advanced > Admin > Remote Management or similar. Attempt to access the router login page from an external network if remote management is enabledAffected if Remote management is enabled and the router is directly accessible from the internet
-
Review admin accounts for unauthorized changesIn the router admin interface, navigate to Administration > Setup > Wireless Setup or the user account management section to review the list of configured administrator accountsAffected if Unexpected administrator accounts exist or account changes were made without your knowledge
-
Monitor for unusual network activityInspect connected devices and network traffic logs for any unexpected devices or unusual outbound connections originating from the router, which could indicate command injection activityAffected if Unknown devices are connected or unusual outbound connections are observed
The device is affected if it is a Netgear XR500, D3600, or D6000 router running firmware versions below 2.3.2.32 (XR500) or below 1.0.0.76 (D3600/D6000) and the admin interface is accessible to untrusted users.

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 data1.0.0.762.3.2.32
Update router firmware to version 1.0.0.76 or later for D3600/D6000, and 2.3.2.32 or later for XR500. If immediate patching is not feasible, limit administrative access to trusted users only and monitor for suspicious activity.
