CVE-2024-44275 is a vulnerability identified in Apple macOS that permits a malicious application to modify protected parts of the file system. This vulnerability stems from inadequate validation checks within the operating system, allowing unauthorized modifications to system files or directories that are normally safeguarded. Apple has resolved this issue by implementing improved validation checks in macOS Ventura 13.7.1 and macOS Sonoma 14.7.1. The vulnerability is classified under CWE-922, which relates to improper restriction of operations within the bounds of a memory buffer or file system. The CVSS v3.1 base score is 3.3, indicating a low severity level. The attack vector is local (AV:L), requiring the attacker to have local access to the system. No privileges are required (PR:N), but user interaction is necessary (UI:R), such as running a malicious application. The scope is unchanged (S:U), and the impact is limited to integrity (I:L) with no confidentiality (C:N) or availability (A:N) impact. There are no known exploits in the wild at this time. This vulnerability could be leveraged by attackers to alter system files, potentially enabling persistence or further local privilege escalation if combined with other vulnerabilities. However, the requirement for local access and user interaction reduces the overall risk. Organizations should ensure timely patching to mitigate this risk.

For European organizations, the primary impact of CVE-2024-44275 lies in the potential compromise of system integrity on macOS devices. Malicious modification of protected file system areas could allow attackers to implant persistent malware, alter system configurations, or bypass security controls. While confidentiality and availability are not directly affected, integrity breaches can lead to indirect impacts such as unauthorized access or system instability. Organizations with macOS endpoints in critical roles—such as software development, secure communications, or infrastructure management—may face increased risk if these systems are compromised. The low severity and requirement for local access limit the threat primarily to insider threats or scenarios where an attacker has already gained some foothold. Nonetheless, failure to patch could facilitate multi-stage attacks or lateral movement within networks. Given the increasing use of Apple devices in European enterprises and government sectors, maintaining system integrity is essential to uphold operational security and trust.

To mitigate CVE-2024-44275, European organizations should: 1) Deploy the security updates macOS Ventura 13.7.1 and macOS Sonoma 14.7.1 promptly across all affected devices to ensure the improved validation checks are in place. 2) Enforce strict application control policies to prevent execution of unauthorized or untrusted applications, reducing the risk of malicious apps running locally. 3) Implement endpoint detection and response (EDR) solutions capable of monitoring file system changes, especially in protected directories, to detect suspicious modification attempts. 4) Educate users about the risks of running untrusted software and the importance of user interaction in exploitation, reinforcing safe computing practices. 5) Limit local user privileges where possible to reduce the impact of local attacks. 6) Regularly audit system integrity using tools like Apple’s System Integrity Protection (SIP) status checks and file integrity monitoring. 7) Integrate macOS patch management into broader IT security workflows to ensure timely updates. These steps go beyond generic advice by focusing on layered defenses and proactive detection tailored to the nature of this vulnerability.
