CVE-2020-3269
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 · uneditedMultiple vulnerabilities in the web-based management interface of Cisco RV110W, RV130, RV130W, and RV215W Series Routers could allow an authenticated, remote attacker with administrative privileges to execute arbitrary commands. For more information about these vulnerabilities, see the Details section of this advisory.
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 confidenceMultiple command injection vulnerabilities exist in the web-based management interface of Cisco RV110W, RV130, RV130W, and RV215W routers. An authenticated attacker with administrative privileges can inject and execute arbitrary operating system commands through insufficient input validation in web interface parameters.

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 and check the device status or system information page, or look at the physical device labelAffected if Model is RV110W, RV130, RV130W, or RV215W
-
Check firmware versionIn the router web interface, navigate to Administration > Firmware Upgrade or Status > System Information to view the installed firmware versionAffected if Firmware version is at or below 1.2.2.5 for RV110W, 1.0.3.54 for RV130/RV130W, or 1.3.1.5 for RV215W
-
Verify web-based management is enabledIn the router web interface, go to Administration > Management > HTTP/HTTPS and check if web-based management is enabledAffected if HTTP or HTTPS management is enabled on any interface
-
Check remote access configurationIn the router web interface, go to Administration > Management > Access Settings and verify if remote management access is permitted from WAN or non-local networksAffected if Remote management is allowed from WAN or untrusted networks (not restricted to LAN-only or trusted IPs)
-
Confirm administrative access existsVerify that administrative user accounts exist and are enabled in the router by checking Administration > User Management or similarAffected if At least one administrative account is configured and enabled
A user is affected if they have any of these four router models running firmware at or below the specified version with web-based management enabled and administrative accounts present.

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 Cisco firmware update for the affected router models. If patching is unavailable, restrict web-based management access to trusted IP addresses only or disable remote management entirely.
