CVE-2024-0230 is a vulnerability in the Apple Magic Keyboard firmware that stems from insufficient session management controls. Specifically, the flaw allows an attacker who gains physical access to the keyboard accessory to extract the Bluetooth pairing key stored within the device. This key is critical for establishing and maintaining a secure Bluetooth connection between the keyboard and its paired host device. By extracting this key, the attacker can potentially monitor Bluetooth traffic, which may include keystrokes or other sensitive data transmitted over the wireless connection. The vulnerability does not allow modification or disruption of data (no integrity or availability impact), nor does it permit remote exploitation, as physical access is a prerequisite. Apple released firmware update 2.0.6 to address this issue by implementing improved session management checks that prevent unauthorized key extraction. The CVSS v3.1 base score is 2.4, indicating low severity, primarily due to the requirement for physical access and the limited confidentiality impact. No known exploits have been reported in the wild, and the affected versions are unspecified but presumed to be all versions prior to 2.0.6. This vulnerability highlights the importance of securing physical access to peripheral devices and maintaining up-to-date firmware to protect Bluetooth communications.

For European organizations, the impact of CVE-2024-0230 is generally low but not negligible. The primary risk is the potential exposure of Bluetooth traffic between the Magic Keyboard and its paired device, which could include sensitive input data such as passwords or confidential information. However, since exploitation requires physical access to the keyboard, the threat is mostly relevant in environments where devices are shared, left unattended, or physically accessible to unauthorized personnel. This could include open office spaces, public workstations, or environments with lax physical security controls. The confidentiality impact is limited to Bluetooth traffic monitoring; integrity and availability of systems are unaffected. Organizations handling sensitive data or operating in regulated sectors (e.g., finance, government, healthcare) should be particularly cautious. The vulnerability does not facilitate remote attacks, so network perimeter defenses are not directly relevant. Overall, the impact is constrained by the attacker's need for physical access and the limited scope of data exposure.

To mitigate CVE-2024-0230, European organizations should take the following specific actions: 1) Ensure all Apple Magic Keyboards are updated to firmware version 2.0.6 or later, which contains the fix for this vulnerability. 2) Implement strict physical security controls to prevent unauthorized access to peripheral devices, including locking workstations and securing peripherals when not in use. 3) Conduct regular audits of peripheral devices to detect any signs of tampering or unauthorized access. 4) Educate employees about the risks of leaving devices unattended and the importance of reporting lost or stolen accessories immediately. 5) Consider using endpoint security solutions that can detect unusual Bluetooth activity or pairing attempts. 6) In high-security environments, evaluate the use of alternative input devices with stronger physical security or encrypted communication protocols. 7) Maintain an inventory of all Bluetooth peripherals to quickly identify and update vulnerable devices. These measures go beyond generic advice by focusing on physical security and firmware management specific to the affected product.
