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 Data Center Network Manager could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections on the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on a targeted device via a web browser and with the privileges of the user. Cisco Bug IDs: CSCvg88291.

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

This is a Cross-Site Request Forgery (CSRF) vulnerability in Cisco Data Center Network Manager's web-based management interface. The interface lacks sufficient CSRF protections, allowing an unauthenticated remote attacker to trick authenticated users into unknowingly executing arbitrary actions by following crafted malicious links. The attacker leverages the existing authenticated session of the victim to perform actions with the user's privileges.

MitigationImplement anti-CSRF tokens on all state-changing operations, validate Origin/Referer headers, and configure SameSite cookie attributes. Cisco typically addresses these vulnerabilities through software updates; check CSCvg88291 for patch availability.

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. Confirm Cisco DCNM is installed
    Locate the Cisco Data Center Network Manager installation. Common paths include /opt/cpnm or check running processes for 'dcnm' or 'CiscoDCNM' services.
    Affected if The product is present in the environment
  2. Identify installed DCNM version
    Run 'dcnm -version' or 'dcnmadmin -version' from the installation directory, or check /opt/cpnm/VERSION file if it exists.
    Affected if Version cannot be determined or matches affected releases
  3. Compare version against affected ranges
    Verify if the installed version is exactly 10.4(1.128) or exactly 10.4(2). These are specific point releases.
    Affected if Version equals 10.4(1.128) or 10.4(2)
  4. Check if web interface is accessible
    Confirm the DCNM web-based management interface is enabled and reachable. Access the login page via HTTPS on port 443 or 8443.
    Affected if Web interface is exposed and the product version is vulnerable

You are affected if Cisco Data Center Network Manager is running version 10.4(1.128) or 10.4(2) and its web interface is accessible to users who could be targeted by CSRF attacks.
