CVE-2024-44287 is a vulnerability identified in Apple macOS that permits a malicious application to modify protected parts of the file system due to inadequate authorization checks (CWE-863). The issue allows unauthorized integrity modifications without requiring privileged access (PR:N) but does require user interaction (UI:R), such as running or installing a malicious app. The vulnerability does not affect confidentiality or availability but impacts system integrity (I:H), potentially enabling attackers to alter critical system files or configurations, which could facilitate persistence, bypass security controls, or disrupt system behavior. The flaw affects macOS versions prior to Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1, where Apple has implemented improved checks to prevent unauthorized modifications. The CVSS 3.1 base score is 5.5 (medium), reflecting local attack vector (AV:L), low attack complexity (AC:L), no privileges required, user interaction required, and unchanged scope. No known exploits have been reported in the wild, indicating limited active exploitation at this time. The vulnerability underscores the importance of strict authorization enforcement in protecting system integrity on macOS platforms.

The primary impact of CVE-2024-44287 is on the integrity of macOS systems. By allowing a malicious application to modify protected file system areas, attackers could implant persistent malware, alter system binaries, or modify security configurations, potentially undermining system trustworthiness. Although confidentiality and availability are not directly affected, integrity compromises can lead to indirect confidentiality breaches or system instability over time. Organizations relying on macOS devices, especially in sensitive environments, risk targeted attacks that leverage this vulnerability to maintain persistence or escalate privileges. The requirement for user interaction limits large-scale automated exploitation but does not eliminate risk from social engineering or supply chain attacks. The absence of known exploits suggests a window of opportunity for defenders to patch systems before widespread abuse occurs. Failure to address this vulnerability could result in compromised endpoints, data tampering, and increased difficulty in incident response and forensic investigations.

1. Immediately apply the security updates provided by Apple in macOS Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1 to ensure the vulnerability is patched. 2. Enforce strict application control policies using Apple’s built-in tools such as Gatekeeper and System Integrity Protection (SIP) to prevent unauthorized or untrusted applications from executing or modifying system files. 3. Educate users about the risks of running untrusted applications and the importance of verifying software sources to reduce the likelihood of user interaction leading to exploitation. 4. Employ endpoint detection and response (EDR) solutions capable of monitoring file system changes in protected areas to detect suspicious modifications indicative of exploitation attempts. 5. Regularly audit system integrity using tools like Apple’s built-in system diagnostics or third-party integrity checkers to identify unauthorized changes promptly. 6. Restrict administrative privileges and use least privilege principles to limit the impact of any compromised user accounts. 7. Monitor security advisories from Apple and threat intelligence feeds for any emerging exploit activity related to this vulnerability.
