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 the installed Cisco Unified CCX or IP IVR version
    Access the system via SSH or console and run the command 'show version' or check the About page in the web management interface to determine the exact software version
    Affected if The installed version is exactly 11.5(1)
  2. Confirm the product type is affected
    Verify the system is either Cisco Unified Contact Center Express or Cisco Unified IP Interactive Voice Response by checking the system name or product identifier in the administration interface
    Affected if The product is Unified CCX or Unified IP IVR running version 11.5(1)
  3. Determine if the web-based management interface is enabled and accessible
    Check if the HTTP/HTTPS management interface is listening on the system by attempting to access the web interface from a network perspective or checking the service status via command line
    Affected if The web-based management interface is exposed and accessible to network users
  4. Check for unauthenticated access to sensitive endpoints
    Review web server logs or attempt to access the password retrieval endpoints that should require authentication, if accessible without credentials the system is vulnerable
    Affected if The management interface allows unauthenticated access to password or configuration data

The environment is affected if Cisco Unified CCX or Unified IP IVR version 11.5(1) is installed and the web-based management interface is accessible, allowing unauthenticated password retrieval.
