CVE-2017-10811
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 · uneditedBuffalo WCR-1166DS devices with firmware 1.30 and earlier allow an attacker to execute arbitrary OS commands 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 confidenceThe Buffalo WCR-1166DS router with firmware 1.30 and earlier contains a command injection vulnerability allowing remote attackers to execute arbitrary operating system commands. The vulnerability stems from insufficient input validation in unspecified firmware components, likely in web interface parameters or network services. This allows an attacker with network adjacency to the device to inject and execute OS-level commands with the privileges of the affected service.

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 modelLog into the router admin interface or check the device label to confirm the model is Buffalo WCR-1166DSAffected if The device is not a Buffalo WCR-1166DS (different models have different vulnerabilities)
-
Check the installed firmware versionAccess the router web interface, navigate to the Administration or System settings section, and locate the firmware version display. Compare it to the affected version 1.30Affected if The firmware version is 1.30 or earlier (versions 1.30 and below are affected)
-
Verify if remote management is enabledIn the router admin interface, check the Administration or Remote Management settings to see if remote access via WAN is enabledAffected if Remote management or WAN access to the web interface is enabled - this allows remote attackers to reach the vulnerable component
-
Determine if the web interface is network-accessibleFrom an external network perspective, attempt to reach the router's HTTP/HTTPS ports or check firewall rules that may expose the management interfaceAffected if The router management interface is exposed to network adjacency (not behind a strict firewall)
You are affected if you are using a Buffalo WCR-1166DS router with firmware version 1.30 or earlier, and the router's management interface is accessible from the network where potential attackers could send malicious commands.

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 the latest Buffalo firmware update for the WCR-1166DS device (firmware versions subsequent to 1.30). If no update is available, restrict network access to the router's management interface using firewall rules or disable remote administration.
