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 · unedited
A vulnerability in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Series Routers could allow an authenticated, remote attacker to inject arbitrary shell commands that are executed by an affected device. The vulnerability is due to insufficient input validation of user-supplied data. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary shell commands or scripts with root privileges on the affected device.

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 confidence

Authenticated command injection in Cisco Small Business RV110W, RV130, RV130W, and RV215W routers web-based management interface. Insufficient input validation allows attackers to inject arbitrary shell commands executing with root privileges via crafted HTTP requests.

MitigationApply Cisco firmware updates when available; meanwhile, restrict web-based management interface access to trusted networks only and disable remote management if not required.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify router model
    Access the router web interface and navigate to Status or Administration pages to view the device model, or inspect the physical device label
    Affected if Model is RV110W, RV130, RV130W, or RV215W
  2. Check installed firmware version
    In the router web interface, go to Administration > Firmware Upgrade or Status page to view the current firmware version
    Affected if Version is below 1.2.2.8 for RV110W, below 1.0.3.55 for RV130/RV130W, or below 1.3.1.7 for RV215W
  3. Verify web-based management is enabled
    In the router web interface, go to Administration > Management or Remote Management settings to check if HTTP or HTTPS web management is enabled
    Affected if Web-based management interface is enabled and accessible

User is affected if they have a vulnerable RV series model running firmware below the specified version with web management interface enabled.
