CVE-2018-0520
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 · uneditedCross-site request forgery (CSRF) vulnerability in FS010W firmware FS010W_00_V1.3.0 and earlier allows an attacker to hijack the authentication of administrators via unspecified vectors.
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 confidenceCross-site request forgery (CSRF) vulnerability in FS010W firmware versions 1.3.0 and earlier allows remote attackers to hijack administrator authentication by tricking authenticated admins into visiting malicious pages or clicking crafted links, enabling unauthorized administrative actions on the device.

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 modelAccess the FS010W device web interface or check the device label/mocumentation to confirm the model is FS010WAffected if The device is an FS010W model
-
Determine the installed firmware versionLog into the FS010W administrative web interface and navigate to System Info, Status, or About page to find the firmware version numberAffected if The firmware version is 1.3.0 or earlier
-
Verify the web administrative interface is accessibleConfirm the device web management interface is reachable on the network (typically via HTTP/HTTPS on the device LAN IP)Affected if The web interface is accessible and used for administration
-
Check for CSRF protection mechanismsInspect the web application forms and requests for presence of anti-CSRF tokens, CSRF headers, or referer validation in the HTML source or network requestsAffected if No CSRF tokens or referer validation is present in administrative forms
A user is affected if the device is an FS010W with firmware version 1.3.0 or earlier and the web administrative interface lacks CSRF protections.

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 dataUpdate FS010W firmware to a version newer than 1.3.0 when available from the vendor; consider implementing additional web application firewall protections or network segmentation as a compensating control until the patch can be applied.
