CVE-2018-14934
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 · uneditedThe Bluetooth subsystem on Polycom Trio devices with software before 5.5.4 has Incorrect Access Control. An attacker can connect without authentication and subsequently record audio from the device microphone.
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 confidenceThe Polycom Trio device Bluetooth subsystem has an incorrect access control vulnerability allowing unauthenticated Bluetooth connections. An attacker within Bluetooth range can connect without authentication and leverage this to record audio from the device microphone.

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.
-
Check the Polycom Trio 8500 firmware versionAccess the device admin interface or web UI and locate the firmware version information, typically found under System Information or About sectionAffected if The displayed firmware version is below 5.5.4 (for example, 5.5.3, 5.5.2, 5.4.x, etc.)
-
Verify Bluetooth subsystem statusAccess the device admin settings and navigate to Bluetooth or Connectivity options to determine if the Bluetooth feature is currently enabledAffected if Bluetooth is enabled on the device
-
Confirm Bluetooth authentication configurationIn the Bluetooth settings menu, examine whether authentication or pairing authentication is required for device connectionsAffected if Authentication is not required or is set to 'none' for Bluetooth connections (allowing unauthenticated pairing)
-
Test Bluetooth pairing from an external deviceUsing a separate Bluetooth-capable device within range, attempt to pair or connect to the Polycom Trio without providing any credentialsAffected if The pairing completes without prompting for a PIN, passkey, or other authentication mechanism
The device is affected if it runs firmware version below 5.5.4 AND has Bluetooth enabled, regardless of security settings, because the vulnerability allows unauthenticated Bluetooth connections.
Generated from the published advisory. Verify against your own configuration.
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 data5.5.4
Update Polycom Trio firmware to version 5.5.4 or later to remediate the authentication bypass in the Bluetooth subsystem.
