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
Multiple vulnerabilities in Cisco Nexus Dashboard could allow an unauthenticated, remote attacker to execute arbitrary commands, read or upload container image files, or perform a cross-site request forgery attack. For more information about these vulnerabilities, see the Details section of this advisory.

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.

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 Cisco Nexus Dashboard installation
    Locate the Nexus Dashboard management interface or check system inventory for Cisco Nexus Dashboard deployment. Access the admin console or API to retrieve version information.
    Affected if The installed version cannot be determined or is not visible in the management interface.
  2. Retrieve the installed software version
    From the Nexus Dashboard admin console, navigate to the version or about page, or use the CLI command 'show version' if accessible. Record the exact version string.
    Affected if The version cannot be retrieved from the system.
  3. Compare version against vulnerable range
    Compare the installed version number to the affected range: versions >= 1.0 and < 2.2(1e). Look for the full version including any build or patch numbers.
    Affected if The installed version falls within >= 1.0 and < 2.2(1e).
  4. Confirm management network exposure
    Check network configuration to determine if the Nexus Dashboard management interface is accessible from untrusted networks or the public internet.
    Affected if The management interface is exposed to untrusted networks without firewall restrictions.

A system is affected if Cisco Nexus Dashboard version is >= 1.0 and < 2.2(1e) and the management interface is network-accessible.
