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 the REST and SOAP API endpoints of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker with administrative privileges on the DCNM application to inject arbitrary commands on the underlying operating system (OS). For more information about these vulnerabilities, see the Details section of this advisory. Note: The severity of these vulnerabilities is aggravated by the vulnerabilities described in the Cisco Data Center Network Manager Authentication Bypass Vulnerabilities advisory, published simultaneously with this one.

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

Multiple vulnerabilities in the REST and SOAP API endpoints of Cisco Data Center Network Manager (DCNM) allow an authenticated attacker with administrative privileges to inject arbitrary commands on the underlying operating system. The attack vector is remote, requiring network access to the DCNM application API.

MitigationApply Cisco-provided patches or upgrade to a fixed version of DCNM. Additionally, restrict network access to DCNM management interfaces and follow least-privilege principles for administrative accounts to reduce exposure, especially given the related authentication bypass vulnerabilities.

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 DCNM installation
    Locate DCNM by checking for the application process or service named 'Cisco Data Center Network Manager' or 'dcnm' on the system. On Windows, check Services; on Linux, check running processes or installed packages.
    Affected if DCNM software is found running or installed on the system
  2. Determine installed DCNM version
    Access the DCNM web interface and navigate to Administration > System Settings > About, or check the installed version via the DCNM installer/binary. Compare the version number to 11.3(1).
    Affected if The installed version is lower than 11.3(1)
  3. Verify REST or SOAP API is enabled
    Check DCNM configuration files (typically in the DCNM installation directory) or web interface settings for REST API and SOAP API endpoint configurations. Look for entries enabling 'REST' or 'SOAP' services.
    Affected if REST API, SOAP API, or both endpoints are enabled in the DCNM configuration
  4. Confirm network accessibility to API endpoints
    Test connectivity to DCNM management ports (default 443 for HTTPS) from external network locations. Review firewall rules and network ACLs allowing access to the DCNM management interface.
    Affected if The DCNM management interface/API ports are reachable from network segments outside the trusted administrative network

The environment is affected if Cisco DCNM is installed with a version lower than 11.3(1) and the REST or SOAP API is network-accessible, regardless of account status.

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.

From vendor data
Upgrade available Upgrade to 11.3 or later
Fixed in 11.3
Interim mitigation

Apply Cisco-provided patches or upgrade to a fixed version of DCNM. Additionally, restrict network access to DCNM management interfaces and follow least-privilege principles for administrative accounts to reduce exposure, especially given the related authentication bypass vulnerabilities.
