CVE-2024-44275 is a security vulnerability identified in Apple macOS that permits a malicious application to modify protected parts of the file system. The root cause is insufficient validation or enforcement of access controls on critical file system areas, categorized under CWE-922 (Improper Restriction of Operations within the Bounds of a Memory Buffer). This flaw allows an attacker, without privileges (PR:N), but requiring local access and user interaction (UI:R), to alter system files or directories that should be protected, potentially undermining system integrity. The vulnerability affects multiple macOS versions prior to the patched releases: macOS Sequoia 15.1, macOS Sonoma 14.7.1, and macOS Ventura 13.7.1. Apple addressed the issue by implementing improved checks to prevent unauthorized modifications. The CVSS v3.1 base score is 3.3, reflecting low severity, with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required, user interaction required, unchanged scope, no confidentiality or availability impact, and limited integrity impact. No public exploits or active exploitation have been reported. This vulnerability could be leveraged by attackers to tamper with system files, potentially facilitating persistence or further attacks, but the requirement for user interaction and local access limits its exploitation scope.

The primary impact of CVE-2024-44275 is on system integrity, where a malicious application could modify protected file system areas, potentially leading to unauthorized changes in system behavior or persistence mechanisms. Although confidentiality and availability are not directly affected, integrity compromises can enable further attacks such as privilege escalation or malware persistence. The requirement for local access and user interaction reduces the likelihood of remote exploitation or widespread automated attacks. However, in environments with many macOS endpoints, especially those with less stringent application control or user awareness, the risk of exploitation increases. Organizations relying heavily on macOS for critical operations could face targeted attacks aiming to undermine system trustworthiness. The absence of known exploits in the wild currently limits immediate risk, but delayed patching could expose systems to future threats. Overall, the impact is moderate due to the limited scope and exploitation conditions but remains significant for security-conscious organizations.

To mitigate CVE-2024-44275, organizations should prioritize updating all affected macOS systems to the patched versions: macOS Sequoia 15.1, macOS Sonoma 14.7.1, and macOS Ventura 13.7.1. Beyond patching, implement strict application whitelisting and endpoint protection to prevent execution of untrusted or malicious applications that could exploit this vulnerability. Employ user training to reduce risky behaviors that might lead to execution of malicious code requiring user interaction. Utilize macOS security features such as System Integrity Protection (SIP) and Full Disk Encryption to limit unauthorized file system modifications and protect data at rest. Regularly audit system file integrity using tools like Tripwire or built-in macOS mechanisms to detect unauthorized changes. Limit local user privileges where possible to reduce the attack surface. Monitor system logs for unusual file system activity indicative of exploitation attempts. Finally, maintain an up-to-date inventory of macOS devices and ensure timely deployment of security updates to reduce exposure.
