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 device model
    Access the device's web interface or check the physical device label to confirm it is a Poly Trio 8800 conference phone
    Affected if The device is not a Poly Trio 8800, then it is not affected by this CVE
  2. Check the installed firmware version
    Navigate to the device web interface (Settings > System Information) or access the device via SSH and run 'sysctl' or 'version' command to retrieve the firmware version
    Affected if The firmware version is exactly 7.2.6.0019 - only this exact version is affected
  3. Verify Test Automation Mode status
    Access the device's diagnostic or maintenance menu via the web interface or physical console to check if Test Automation Mode is enabled or accessible
    Affected if Test Automation Mode is enabled or accessible on the device

You are affected only if you have a Poly Trio 8800 with firmware version exactly 7.2.6.0019 AND Test Automation Mode is enabled or accessible on the device.
