CVE-2016-1397
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 · uneditedBuffer overflow in the web-based management interface on Cisco RV110W devices with firmware before 1.2.1.7, RV130W devices with firmware before 1.0.3.16, and RV215W devices with firmware before 1.3.0.8 allows remote authenticated users to cause a denial of service (device reload) via crafted configuration commands in an HTTP request, aka Bug ID CSCux82523.
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 confidenceBuffer overflow in the web-based management interface on Cisco RV110W, RV130W, and RV215W routers allows remote authenticated users to cause denial of service via crafted configuration commands in HTTP requests, triggering device reload.

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 modelLog into the device web interface or check the device label to confirm the model is RV110W, RV130W, or RV215WAffected if Model is one of RV110W, RV130W, or RV215W
-
Check firmware versionAccess the router web interface, navigate to Status or System Summary page to view the firmware version, or use the command line and run 'show version'Affected if Firmware version matches 1.1.0.5, 1.1.0.6, 1.2.0.14, 1.2.0.15, 1.3.0.7 (RV215W); 1.1.0.9, 1.2.0.9, 1.2.0.10, 1.2.1.4 (RV110W); or 1.0.0.21, 1.0.1.3, 1.0.2.7 (RV130W)
-
Verify web-based management is enabledIn the router web interface, go to Administration or Management settings and check if HTTP/HTTPS management access is enabledAffected if Web-based management interface is enabled and accessible
-
Check remote access configurationIn the router web interface, examine the management access settings to determine if remote (WAN) access to the web interface is permittedAffected if Remote authenticated users can access the web management interface from outside the local network
The device is affected if it is an RV110W, RV130W, or RV215W router running one of the listed firmware versions AND the web-based management interface is accessible to remote authenticated 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 dataUpgrade firmware to the latest version (RV110W: 1.2.1.7+, RV130W: 1.0.3.16+, RV215W: 1.3.0.8+). If immediate upgrade is not feasible, restrict web management interface access to trusted IP addresses or networks only.
