CVE-2017-18861
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 ReadyNAS Surveillance 1.4.3-15-x86 and earlier and ReadyNAS Surveillance 1.1.4-5-ARM and earlier.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in NETGEAR ReadyNAS Surveillance firmware (versions 1.4.3-15-x86 and earlier for x86, 1.1.4-5-ARM and earlier for ARM). Attackers can trick authenticated users into executing unintended administrative actions by sending malicious requests through the user's browser.

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 if NETGEAR ReadyNAS Surveillance is installedAccess the device admin interface or check system information page for the ReadyNAS Surveillance application versionAffected if The application is present and running on the device
-
Determine the installed firmware version for x86 architectureNavigate to the device admin panel, look for System > Firmware or About section, and record the ReadyNAS Surveillance version numberAffected if Version is 1.4.3-15 or lower on x86 systems
-
Determine the installed firmware version for ARM architectureNavigate to the device admin panel, look for System > Firmware or About section, and record the ReadyNAS Surveillance version numberAffected if Version is 1.1.4-5 or lower on ARM systems
-
Confirm web interface accessibilityAttempt to access the device web interface on the typical ports (typically 80/443) from a browserAffected if The web management interface is reachable from network segments where untrusted browsing may occur
A user is affected if NETGEAR ReadyNAS Surveillance version is at or below 1.4.3-15 for x86 or 1.1.4-5 for ARM, and the web interface is accessible to users who might browse untrusted sites while authenticated.

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 dataApply vendor firmware updates when available; as a workaround, avoid browsing untrusted sites while authenticated to the device and use network isolation/VPNs to limit exposure to the device's web interface.
