CVE-2019-20743
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 · uneditedNETGEAR WAC510 devices before 8.0.1.3 are affected by stored XSS.
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 confidenceNETGEAR WAC510 wireless access point devices before firmware version 8.0.1.3 contain a stored cross-site scripting (XSS) vulnerability. This allows attackers to inject malicious scripts into the device's web interface that are persistently stored and executed when other users interact with the affected component.

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 the device firmware versionAccess the NETGEAR WAC510 web management interface and navigate to the Administration or Maintenance section to view the current firmware version. Alternatively, check via CLI using 'show version' or the device's SNMP interface if configured.Affected if The displayed firmware version is below 8.0.1.3
-
Confirm the web interface is activeVerify that the device's HTTP/HTTPS management interface is enabled and reachable on the network. Check device network settings or attempt to reach the device's management IP address.Affected if The web interface is enabled and accessible, and the firmware version is below 8.0.1.3
-
Assess management interface exposureReview network segmentation, firewall rules, or VLAN configurations to determine whether the device's web management interface is accessible from untrusted network segments or external networks.Affected if The management interface is exposed to untrusted users or networks, and the firmware version is below 8.0.1.3
The device is affected if it runs firmware version 8.0.1.3 or earlier and has its web management interface accessible to potential attackers who could inject stored XSS payloads.

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 data8.0.1.3
Update NETGEAR WAC510 firmware to version 8.0.1.3 or later to resolve the stored XSS vulnerability. If immediate patching is not feasible, restrict administrative access to trusted personnel and monitor for suspicious activity.
