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 Cisco Nexus Dashboard could allow an authenticated, remote attacker to write arbitrary files on an affected device. This vulnerability is due to insufficient input validation in the web-based management interface of Cisco Nexus Dashboard. An attacker with Administrator credentials could exploit this vulnerability by uploading a crafted file. A successful exploit could allow the attacker to overwrite arbitrary files on an 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

A file write vulnerability in Cisco Nexus Dashboard's web-based management interface allows an authenticated attacker with Administrator privileges to upload crafted files that overwrite arbitrary files on the device filesystem. The root cause is insufficient input validation on file upload operations.

MitigationApply Cisco's security updates for this vulnerability. Until patched, limit Administrator access to only trusted personnel and monitor the web management interface for suspicious file upload activity.

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 Nexus Dashboard is installed
    Identify if the system is running Cisco Nexus Dashboard. This is typically done by checking the product name in the system UI or via CLI commands like 'show version' or checking system information.
    Affected if The system is NOT Cisco Nexus Dashboard (this CVE only applies to Cisco Nexus Dashboard)
  2. Check the installed version
    Use the web management interface or CLI to determine the exact version number of Cisco Nexus Dashboard. In the CLI, this may be available via 'show version' or similar commands. Compare your version against the affected range: >= 2.0 and < 2.2(1e).
    Affected if The installed version falls within 2.0 to 2.2(1e) exclusive (any version >= 2.0 but earlier than 2.2(1e))
  3. Verify web-based management interface is enabled
    Check if the web-based management interface (HTTP/HTTPS) is accessible and enabled on the Cisco Nexus Dashboard. This is typically configured in the management settings.
    Affected if The web-based management interface is enabled and accessible (this is the attack vector for the vulnerability)
  4. Confirm Administrator accounts exist
    Review the local user accounts configured on Cisco Nexus Dashboard, specifically checking for accounts with Administrator-level privileges.
    Affected if At least one Administrator account exists (an authenticated attacker with Administrator privileges is required to exploit this vulnerability)

You are affected if you are running Cisco Nexus Dashboard version 2.0 through 2.2(1e) with the web-based management interface enabled and at least one Administrator account configured.

Interim mitigation

Apply Cisco's security updates for this vulnerability. Until patched, limit Administrator access to only trusted personnel and monitor the web management interface for suspicious file upload activity.

Recommended fix High confidence

Cisco Nexus Dashboard version 2.2(1e) or later

  1. 1. Back up the current Nexus Dashboard configuration and any critical data.
  2. 2. Download the Cisco Nexus Dashboard software version 2.2(1e) or later from Cisco's official download site (tools.cisco.com).
  3. 3. Access the Nexus Dashboard web-based management interface with Administrator credentials.
  4. 4. Navigate to the Administration or System Upgrade section of the management interface.
  5. 5. Upload the downloaded upgrade image (.iso or as specified by Cisco).
  6. 6. Initiate the upgrade process and monitor for successful completion.
  7. 7. After upgrade, verify the system is running version 2.2(1e) or later by checking the web interface or CLI.
  8. 8. Verify that all services are functioning normally and the vulnerability is remediated.
