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 Smart Software Manager Satellite is installed
    Locate the installation directory or check system services for 'Cisco Smart Software Manager Satellite' or 'cssms' processes. On Linux, check for /opt/cisco/satellite or similar installation paths.
    Affected if The product is present on the system
  2. Identify the installed version
    Check the version of Cisco Smart Software Manager Satellite. Common methods include: reviewing installation logs, checking the about page in the web UI, or running 'cssms --version' if CLI is available. Compare against the affected range: <= 5.1.0
    Affected if The installed version is 5.1.0 or earlier
  3. Verify the web UI is enabled and accessible
    Confirm the web interface service is running and accessible. Check if ports 443 or 8443 are listening for the web UI, or verify the service status via 'systemctl status cssms' or equivalent.
    Affected if The web UI service is running and network-accessible
  4. Confirm web UI is exposed to network
    Review firewall rules and network configuration to determine if the web interface is bound to routable network interfaces rather than localhost only.
    Affected if The web UI is bound to non-loopback interfaces or accessible from external networks

You are affected if Cisco Smart Software Manager Satellite version 5.1.0 or earlier is installed and the web UI is accessible on the network.
