Apple Mac OS X up to 10.9.3 Bluetooth cryptographic issues

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Apple Mac OS X up to 10.9.3 (Operating System) and classified as critical. Affected by this issue is some unknown functionality of the component Bluetooth. The manipulation with an unknown input leads to a weak encryption vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality, integrity, and availability.

The weakness was published 10/16/2014 by Mike Ryan with iSEC Partners as HT6535 as confirmed advisory (Website). The advisory is shared for download at This vulnerability is handled as CVE-2014-4428 since 06/20/2014. The attack can only be initiated within the local network. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600. The advisory points out:

Unencrypted connections were permitted from Human Interface Device-class Bluetooth Low Energy devices. If a Mac had paired with such a device, an attacker could spoof the legitimate device to establish a connection.

The vulnerability scanner Nessus provides a plugin with the ID 78871 (Apple TV < 7.0.1 Multiple Vulnerabilities (POODLE)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Misc..

Upgrading to version 10.10 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

The issue was addressed by denying unencrypted HID connections.
