CVE-2014-7270
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 on ASUS JAPAN RT-AC87U routers with firmware 3.0.0.4.378.3754 and earlier, RT-AC68U routers with firmware 3.0.0.4.376.3715 and earlier, RT-AC56S routers with firmware 3.0.0.4.376.3715 and earlier, RT-N66U routers with firmware 3.0.0.4.376.3715 and earlier, and RT-N56U routers with firmware 3.0.0.4.376.3715 and earlier allows remote attackers to hijack the authentication of arbitrary users.
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 the web management interface of multiple ASUS JAPAN router models (RT-AC87U, RT-AC68U, RT-AC56S, RT-N66U, RT-N56U) allows remote attackers to hijack the authentication of authenticated users by tricking them into visiting malicious web pages that send requests to the router's web interface.

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 your ASUS router modelCheck the device label on the router or log into the web management interface and look for the model name typically displayed on the main status pageAffected if The model is RT-AC87U, RT-AC68U, RT-AC56S, RT-N66U, or RT-N56U
-
Check the installed firmware versionLog into the router web interface, navigate to the Administration or Firmware Upgrade section, and locate the firmware version displayed. Compare it against the affected version thresholds: RT-AC87U <= 3.0.0.4.378.3754; RT-N66U, RT-N56U, RT-AC68U <= 3.0.0.4.376.3715Affected if The firmware version is at or below the threshold for your specific model, or if the firmware version cannot be determined and your model is listed as affected at all versions
-
Verify if the web management interface is enabledLog into the router and check the Administration > System or Access Control settings to confirm the HTTP/HTTPS web interface is currently enabledAffected if The web management interface is enabled - this is required for the CSRF vulnerability to be exploitable
-
Check if remote WAN access to the web interface is enabledIn the router web interface, navigate to the WAN or External Management settings (often under Administration > System > WAN Access) and determine if remote access to the web management interface is permitted from the internetAffected if Remote WAN access to the web interface is enabled - this makes the CSRF vulnerability exploitable from outside the local network
You are affected if you own one of the listed router models AND the web management interface is enabled, with the risk being higher if remote WAN access is also enabled.

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 to versions newer than 3.0.0.4.378.3754 (RT-AC87U) or 3.0.0.4.376.3715 (other models). If updates are unavailable, consider network segmentation or disabling remote web management.
