CVE-2018-0424
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 · uneditedA vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router could allow an authenticated, remote attacker to execute arbitrary commands. The vulnerability is due to improper validation of user-supplied input to scripts by the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary commands with the privileges of the root user.
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.

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 router modelAccess the router web interface or check the device label to confirm the model is RV110W, RV130W, or RV215WAffected if Model is one of these three and firmware version is within affected range
-
Check firmware versionLog into the web-based management interface and navigate to Status > System Summary or similar to view the firmware version. Alternatively, check via CLI if available.Affected if RV110W version is 1.2.1.7 or lower, RV130W version is below 1.0.3.44, or RV215W version is 1.3.0.8 or lower
-
Verify remote web management is enabledIn the router web interface, go to VPN > Remote Management or Administration > Remote Management to check if remote access via HTTP/HTTPS is enabled for external IPs or untrusted networksAffected if Remote web-based management is enabled and accessible from untrusted networks (internet-facing)
-
Confirm authentication is reachableVerify that the management interface is accessible over the network and that valid admin credentials exist or can be configuredAffected if Attacker can reach the login page and obtain or already has valid admin credentials
User is affected if they have a Cisco RV110W, RV130W, or RV215W router running a firmware version within the affected ranges AND remote web-based management is accessible from untrusted networks with valid credentials.

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 data1.0.3.44
Apply the Cisco firmware update for affected devices. As a compensating control, disable remote web-based management access from untrusted networks and restrict management to VPN-connected users.
