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 vManage web-based UI (web UI) of the Cisco SD-WAN Solution could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected instance of vManage. An attacker could exploit this vulnerability by persuading a user to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user.

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

The vulnerability is a Cross-Site Request Forgery (CSRF) flaw in Cisco SD-WAN vManage's web UI. An unauthenticated remote attacker can craft malicious links that, when clicked by an authenticated user, cause the user's browser to perform unauthorized actions with that user's privileges due to missing or inadequate CSRF token validation.

MitigationApply the Cisco security patch for CVE-2019-16002. As a compensating control, enable SameSite cookie attributes on session cookies and implement strict Origin/Referer header validation on the vManage server.

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 vManage software version
    Log into the vManage CLI and run 'show version' or access the web UI and navigate to Administration > About to view the software version number
    Affected if The displayed version is earlier than 19.2.0 (for example, 18.x, 19.1.x, or any release prior to the 19.2.0 patch)
  2. Confirm the vManage web UI is enabled
    Check via CLI with 'show web-server details' or 'show running-config | include web' to see if the web-based management interface is active
    Affected if The web UI is enabled and accessible to users, as this is the attack vector for the CSRF flaw
  3. Verify CSRF protection is absent in HTTP responses
    Using a web proxy or browser developer tools, capture a login response to vManage and inspect whether the Set-Cookie headers include CSRF tokens or SameSite attributes, and whether subsequent POST requests to the API require a valid CSRF token header
    Affected if No CSRF token is generated and validated for state-changing requests, or the SameSite cookie attribute is missing from session cookies

A system is affected if it runs any version of Cisco SD-WAN vManage prior to 19.2.0 and has the web UI enabled, with no CSRF token validation present in the application.
