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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Cisco Smart Software Manager Satellite is installedLocate the installation directory or check system services for Cisco Smart Software Manager Satellite. On Linux, check for /opt/cssc/satellite or similar installation paths. On Windows, check Program Files for Cisco SSM Satellite.Affected if The product is not installed on the system
-
Check the installed versionAccess the web UI and navigate to the Administration or System Info page to view the version number. Alternatively, check the installation directory for a version file or run 'show version' via CLI if available.Affected if The version is 5.1.0 or any version lower than 5.1.0
-
Verify the web UI is accessibleAttempt to reach the web interface by accessing the hostname or IP on the configured HTTP/HTTPS port (typically 8443 or 443). Confirm the login page loads.Affected if The web UI is reachable from the network and the version is 5.1.0 or lower
-
Assess network exposure of the web UIReview firewall rules, ACLs, or network segmentation to determine if the web UI interface is exposed to untrusted or external networks. Check if the management interface is on a DMZ or directly internet-facing.Affected if The web UI is accessible from untrusted networks and the version is 5.1.0 or lower
A system is affected if Cisco Smart Software Manager Satellite version 5.1.0 or lower is installed and its web UI interface is network-accessible.
