CVE-2020-3150
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 Cisco Small Business RV110W and RV215W Series Routers could allow an unauthenticated, remote attacker to download sensitive information from the device, which could include the device configuration. The vulnerability is due to improper authorization of an HTTP request. An attacker could exploit this vulnerability by accessing a specific URI on the web-based management interface of the router, but only after any valid user has opened a specific file on the device since the last reboot. A successful exploit would allow the attacker to view sensitive information, which should be restricted.

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 device model and firmware versionAccess the router's web management interface and navigate to Status > System Summary or use CLI command 'show version' to view the firmware versionAffected if The device is a Cisco RV110W with firmware < 1.2.2.8, or a Cisco RV215W with firmware < 1.3.1.7
-
Check if remote web management is enabledLog into the router web interface and go to Firewall > Remote Management, or check via CLI under 'ip http server' or 'ip https server' settingsAffected if Remote web management (HTTP or HTTPS) is enabled and accessible from untrusted networks
-
Verify web service is runningAttempt to access the router's HTTP/HTTPS ports from the WAN interface (port 80/443) or use 'show service internal' via CLIAffected if The web management interface responds to requests from the network where untrusted users exist
The environment is affected if the router is a vulnerable RV110W or RV215W model with firmware below the fixed versions AND the web-based management interface is accessible to untrusted users.

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 data1.2.2.81.3.1.7
Apply the Cisco firmware update for this vulnerability. If patching is not immediately feasible, restrict access to the router's web management interface to trusted internal networks or disable remote web management.
