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.

dbcve analysis · moderate confidence

Multiple critical vulnerabilities in Cisco Nexus Dashboard allow an unauthenticated remote attacker to execute arbitrary commands on the underlying system, read or upload container image files, and perform cross-site request forgery attacks. The critical CVSS score of 9.8 reflects the severe impact of unauthenticated command execution combined with the exposed network attack surface.

MitigationApply the vendor-supplied patches for Cisco Nexus Dashboard immediately. If patches are unavailable, restrict network access to the management interface and monitor for indicators of compromise.

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 and determine the installed version of Cisco Nexus Dashboard in your environment. Consult your inventory systems, running services, or use vendor-specific commands to retrieve the version number.
    Affected if The installed version is >= 2.0 and < 2.2(1e)
  2. Confirm the product is running
    Verify that Cisco Nexus Dashboard is actively running on the system. Check for running processes or services associated with this product.
    Affected if The product is running and the version falls within the vulnerable range
  3. Assess management interface exposure
    Examine network configuration to determine if the Cisco Nexus Dashboard management interface is accessible from untrusted networks. Review firewall rules, ACLs, and interface bindings.
    Affected if The management interface is exposed to untrusted networks (this increases exploitation risk based on the CVSS description of exposed network attack surface)
  4. Review for indicators of compromise
    Examine system logs, audit logs, and network traffic for signs of unauthorized command execution, unexpected container image access, or anomalous cross-site request forgery patterns.
    Affected if Any indicators of compromise are found that align with the described vulnerabilities (arbitrary command execution, unauthorized container access)

You are affected if Cisco Nexus Dashboard version 2.0 or later but earlier than 2.2(1e) is running in your environment, particularly if the management interface is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 2.2 or later
Fixed in 2.2
Interim mitigation

Apply the vendor-supplied patches for Cisco Nexus Dashboard immediately. If patches are unavailable, restrict network access to the management interface and monitor for indicators of compromise.

Recommended fix High confidence

Nexus Dashboard version 2.2(1e) or later (e.g., 2.3.x, 3.x)

  1. 1. Backup current Nexus Dashboard configuration and data
  2. 2. Schedule a maintenance window for the upgrade
  3. 3. Download the Nexus Dashboard version 2.2(1e) or later from Cisco (requires valid CCO account)
  4. 4. Follow Cisco's official upgrade procedure for Nexus Dashboard - refer to the upgrade guide for your current version
  5. 5. Verify the upgrade was successful by logging into the Nexus Dashboard
  6. 6. Confirm the vulnerabilities are remediated by checking the Cisco security advisory
Caveat Review Cisco release notes for breaking changes between your current version and 2.2(1e); some features or integrations may require reconfiguration
