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 Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to improper validation of requests that are sent to the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary code with root privileges on an affected device. To exploit this vulnerability, the attacker must have valid Administrator credentials 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 vulnerability in Cisco Small Business RV series routers (RV110W, RV130, RV130W, RV215W). The web-based management interface fails to properly validate requests, allowing an attacker with valid Administrator credentials to send crafted requests that result in arbitrary code execution with root privileges.

MitigationApply Cisco firmware updates when available; if no patch exists, restrict web management interface access to trusted networks only, enforce strong Administrator passwords, and consider disabling remote management entirely.

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 the router model
    Access the router web interface and navigate to Status or System Summary page, or inspect the physical device label
    Affected if Device model is RV110W, RV130, RV130W, or RV215W
  2. Check the firmware version
    Log into the web interface and go to Status > System Summary to view the firmware version, or check via CLI if available
    Affected if Firmware version is exactly 1.0.0.2, 1.0.0.21, 1.0.0.30, 1.0.1.1, 1.0.1.3, 1.0.1.6, 1.0.1.99, 1.0.2.7, 1.0.2.99, 1.0.3.14, 1.0.3.16, or 1.0.3.22
  3. Verify Administrator access is possible
    Attempt to log into the web interface with valid Administrator credentials
    Affected if Valid Administrator credentials can be used to authenticate to the web interface

If the device is an RV110W, RV130, RV130W, or RV215W running one of the listed firmware versions AND the web management interface is accessible with valid Administrator credentials, the environment is affected by CVE-2023-20250.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Cisco firmware updates when available; if no patch exists, restrict web management interface access to trusted networks only, enforce strong Administrator passwords, and consider disabling remote management entirely.

Recommended fix Moderate confidence

Firmware version specified in Cisco Security Advisory for CVE-2023-20250 (check sec.cloudapps.cisco.com for the exact fixed release for your model)

  1. 1. Identify the exact router model (RV110W, RV130, RV130W, or RV215W) from the affected device.
  2. 2. Access the Cisco Security Advisories page at sec.cloudapps.cisco.com and search for CVE-2023-20250.
  3. 3. Locate the advisory for Cisco Small Business RV Series Routers Management Interface Arbitrary Code Execution vulnerability.
  4. 4. Download the firmware update version specified in the Fixed Releases section for your specific router model.
  5. 5. Back up the current router configuration.
  6. 6. Log in to the router's web-based management interface as Administrator.
  7. 7. Navigate to the Administration or System section and locate the firmware upgrade option.
  8. 8. Upload and apply the new firmware version.
Caveat Review Cisco release notes for any configuration changes required after upgrade; ensure Administrator credentials are maintained
