CVE-2006-6899
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 · uneditedhidd in BlueZ (bluez-utils) before 2.25 allows remote attackers to obtain control of the (1) Mouse and (2) Keyboard Human Interface Device (HID) via a certain configuration of two HID (PSM) endpoints, operating as a server, aka HidAttack.
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 · moderate confidenceThe hidd daemon in bluez-utils before version 2.25 contains a vulnerability where remote attackers can obtain control of Human Interface Devices (mouse and keyboard) by exploiting a specific configuration of two HID Protocol Service Multiplexer (PSM) endpoints when the daemon operates as a server. This allows an attacker to potentially inject keystrokes or control mouse movements remotely via Bluetooth.

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.
-
Verify bluez-utils package installationQuery the system package manager for the installed bluez or bluez-utils package (e.g., rpm -q bluez, dpkg -l bluez-utils, or similar).Affected if Package is installed with version 2.24 or lower
-
Confirm hidd daemon is runningCheck for running hidd process using process listing commands (e.g., ps aux | grep hidd, pgrep hidd).Affected if hidd daemon is currently active as a running process
-
Identify hidd server mode configurationInspect hidd configuration files or runtime settings to determine if it is operating in server mode (listening for incoming Bluetooth HID connections).Affected if hidd is configured to accept incoming HID connections from remote devices
-
Verify PSM endpoint configurationExamine hidd configuration or Bluetooth setup for the presence of HID Protocol Service Multiplexer endpoints that enable the daemon to act as a server for HID devices.Affected if HID PSM endpoints are configured enabling the server functionality
User is affected if bluez-utils version 2.24 or lower is installed AND the hidd daemon is running in server mode with HID PSM endpoints configured, allowing remote Bluetooth HID device connections.

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 dataUpgrade bluez-utils to version 2.25 or later. If upgrading is not feasible, restrict Bluetooth device pairing to trusted devices only and disable HID server functionality if not required.
