CVE-2021-1150
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 Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges. The vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on an affected device. Cisco has not released software updates that address these vulnerabilities.
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 in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers allow authenticated administrators to inject and execute arbitrary OS commands with root privileges via crafted HTTP requests due to improper input validation.

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 web interface or check the device label to confirm the model is RV110W, RV130, RV130W, RV215W, or identify if Cisco Application Extension Platform is installedAffected if The device is one of: RV110W, RV130, RV130W, RV215W, or Application Extension Platform
-
Check the firmware versionIn the router web interface, navigate to Status > System Summary or Administration > Firmware Upgrade to find the installed firmware versionAffected if The firmware version is exactly 1.2.2.8 or 1.3.1.7 for router models, or exactly 1.0.3.55 for Application Extension Platform
-
Verify web management interface is enabledConfirm the web-based management interface is enabled on the device (typically accessible via HTTP/HTTPS on port 80/443)Affected if The web-based management interface is enabled and accessible on the network
The device is affected if it is an RV110W, RV130, RV130W, or RV215W router running firmware version 1.2.2.8 or 1.3.1.7 (or Application Extension Platform version 1.0.3.55) and the web management interface is enabled, allowing authenticated administrators to inject commands via crafted HTTP requests.

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 dataSince Cisco has not released patches, organizations should restrict network access to the management interface to trusted admin networks only, consider replacing affected devices, and monitor for suspicious HTTP activity.
