CVE-2024-44137 is a vulnerability identified in Apple macOS that allows an attacker with physical access to the device to share items directly from the lock screen. This occurs due to insufficient authorization checks that fail to properly restrict sharing capabilities when the system is locked. The vulnerability affects macOS versions prior to Sequoia 15, Sonoma 14.7.1, and Ventura 13.7.1, where Apple has implemented improved authorization checks to resolve the issue. The Common Weakness Enumeration associated with this vulnerability is CWE-863, which relates to incorrect authorization. The CVSS v3.1 base score is 4.6, indicating a medium severity level, with an attack vector requiring physical access (AV:P), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). This means an attacker can potentially exfiltrate sensitive data from the device without needing to authenticate or interact with the user, but must have physical access to the device. No known exploits are currently reported in the wild. The vulnerability highlights a risk to confidentiality by allowing unauthorized sharing of items from the lock screen, which could lead to data leakage. Apple has addressed this vulnerability in recent macOS updates, and users are advised to upgrade to the fixed versions to mitigate the risk.

The primary impact of CVE-2024-44137 is a breach of confidentiality, as an attacker with physical access can share items from the lock screen without authentication. This could lead to unauthorized disclosure of sensitive or private information stored on the device. While the vulnerability does not affect integrity or availability, the ability to bypass lock screen restrictions undermines the security model of macOS devices. Organizations relying on macOS for sensitive operations or handling confidential data face increased risk of data leakage if devices are lost, stolen, or accessed by unauthorized personnel. The requirement for physical access limits remote exploitation but does not eliminate risk in environments where devices are shared, left unattended, or physically accessible to adversaries. The absence of known exploits in the wild reduces immediate threat but does not preclude future exploitation. Overall, this vulnerability could facilitate insider threats, targeted physical attacks, or opportunistic data theft, impacting privacy and compliance obligations.

To mitigate CVE-2024-44137, organizations and users should immediately update affected macOS systems to the patched versions: macOS Sequoia 15, macOS Sonoma 14.7.1, or macOS Ventura 13.7.1. Beyond patching, physical security controls should be enhanced to prevent unauthorized access to devices, including the use of secure storage, locked rooms, or cable locks. Enabling FileVault full-disk encryption can reduce data exposure even if the lock screen is bypassed. Configure macOS settings to minimize lock screen functionality that could be exploited, such as disabling sharing options or limiting lock screen widgets. Employ endpoint management solutions to enforce security policies and monitor device access. Educate users on the importance of locking devices when unattended and reporting lost or stolen hardware promptly. Regularly audit macOS devices for compliance with security configurations and update policies to address physical access risks. Consider multi-factor authentication for device access where possible to strengthen security posture.
