CVE-2024-44177 is a privacy vulnerability identified in Apple macOS that allows an application with low privileges (PR:L) and local access (AV:L) to access sensitive user data without requiring user interaction (UI:N). The vulnerability does not affect system integrity or availability but poses a confidentiality risk by exposing sensitive data that should have been protected. Apple addressed this issue by removing the sensitive data exposure in macOS Sequoia 15, macOS Sonoma 14.7, and macOS Ventura 13.7. The CVSS v3.1 base score is 5.5, reflecting a medium severity level due to the high confidentiality impact but limited attack vector (local access required) and low complexity (AC:L). The vulnerability does not require user interaction and does not escalate privileges, but it allows an app running with limited privileges to access data that should be inaccessible. No known exploits are currently reported in the wild, indicating the issue is newly disclosed and patched promptly. This vulnerability underscores the importance of strict data access controls and sandboxing in macOS to prevent unauthorized data exposure by local applications.

The primary impact of CVE-2024-44177 is the unauthorized disclosure of sensitive user data to local applications with limited privileges. This can lead to privacy violations, potential leakage of personal or confidential information, and increased risk of targeted attacks if sensitive data is harvested. Organizations relying on macOS devices, especially in environments with multiple users or shared systems, may face risks of data exposure from malicious or compromised local apps. Although the vulnerability does not affect system integrity or availability, the confidentiality breach can undermine user trust and compliance with data protection regulations. The requirement for local access limits remote exploitation, but insider threats or malware with local presence could exploit this vulnerability. The absence of known exploits reduces immediate risk but does not eliminate the need for timely patching to prevent future exploitation.

To mitigate CVE-2024-44177, organizations and users should promptly update affected macOS systems to versions Sequoia 15, Sonoma 14.7, or Ventura 13.7 or later, where the vulnerability is fixed. Beyond patching, administrators should enforce strict application control policies to limit installation and execution of untrusted or unnecessary local applications. Implementing endpoint detection and response (EDR) solutions can help monitor for suspicious local app behavior that attempts to access sensitive data. Regularly auditing app permissions and sandboxing configurations can reduce the risk of unauthorized data access. For environments with shared macOS devices, enforcing user account separation and limiting privilege escalation can further reduce exposure. Educating users about the risks of installing unverified applications and maintaining robust local security hygiene are also important. Finally, monitoring for updates from Apple and applying security patches promptly remains critical.
