CVE-2024-44300 is a logic flaw in Apple macOS's file handling mechanisms that could allow a malicious application to access protected user data improperly. The vulnerability arises from insufficient checks or incorrect logic in how the operating system manages file access permissions, enabling an app to bypass normal protection boundaries. This issue affects multiple macOS versions prior to the patched releases: macOS Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2. The vulnerability requires local access to the system and user interaction to trigger, but does not require elevated privileges or prior authentication. The CVSS 3.1 base score is 5.5 (medium), reflecting the attack vector as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). Although no known exploits are currently reported in the wild, the flaw could be leveraged by malicious apps or threat actors to exfiltrate sensitive user data such as personal files, credentials, or other protected information. Apple has addressed the issue by improving file handling logic in the specified macOS versions. The vulnerability highlights the importance of robust access control and validation in OS file management components to prevent unauthorized data access.

The primary impact of CVE-2024-44300 is unauthorized disclosure of protected user data on affected macOS systems. This can lead to privacy violations, leakage of sensitive personal or corporate information, and potential downstream attacks such as identity theft or targeted phishing. Since the vulnerability does not affect integrity or availability, it does not enable data modification or system disruption. However, the confidentiality breach alone can be significant, especially in environments handling sensitive or regulated data. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, particularly in scenarios involving social engineering or insider threats. Organizations with macOS endpoints in sectors such as finance, healthcare, government, and technology may face increased risk due to the value of the data potentially exposed. The absence of known exploits in the wild reduces immediate threat but does not preclude future exploitation attempts, making timely patching critical to minimize exposure.

To mitigate CVE-2024-44300, organizations and users should promptly apply the security updates released by Apple in macOS Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2. Beyond patching, implement strict application control policies to limit installation and execution of untrusted or unsigned apps, reducing the risk of malicious apps exploiting this vulnerability. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local activity indicative of attempts to access protected data. Educate users about the risks of interacting with untrusted applications or links to minimize the likelihood of user interaction exploitation. Regularly audit file permissions and access controls on sensitive data to ensure no unnecessary exposure exists. Consider deploying macOS security features such as System Integrity Protection (SIP) and privacy preferences to further restrict app access to user data. Maintain comprehensive backup and incident response plans to quickly address any potential data breaches resulting from exploitation.
