CVE-2024-44159 is a vulnerability identified in Apple macOS that allows an application to bypass the system's Privacy preferences, potentially exposing sensitive user data or system resources that are normally protected. The root cause is a path deletion vulnerability, which was mitigated by preventing the vulnerable code from executing with elevated privileges. This flaw permits an app running with limited privileges (low privilege level) to circumvent privacy restrictions without requiring user interaction, thereby compromising confidentiality and integrity of protected data. The vulnerability affects macOS versions prior to Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1, where the issue has been fixed. The CVSS v3.1 base score is 7.1, indicating a high severity level, with an attack vector of local access, low attack complexity, low privileges required, no user interaction, and unchanged scope. While no exploits have been observed in the wild, the potential for abuse exists, especially in environments where untrusted applications may be executed. The vulnerability underscores the importance of strict privilege separation and robust enforcement of privacy controls within the macOS ecosystem.

The primary impact of CVE-2024-44159 is the unauthorized bypass of macOS Privacy preferences, which can lead to exposure of sensitive user data such as location, contacts, calendars, or other protected resources. This breach of confidentiality can facilitate further attacks, including data exfiltration or privilege escalation chains. Integrity may also be affected if the attacker modifies protected data or settings. Since the vulnerability does not impact availability, denial-of-service is not a concern here. Organizations relying on macOS devices, especially those handling sensitive or regulated data, face increased risk of privacy violations and compliance issues if unpatched. The requirement for local access and low privileges means that insider threats or malware with limited permissions could exploit this vulnerability. The absence of user interaction lowers the barrier for automated exploitation once local access is obtained. Overall, the vulnerability poses a significant risk to data privacy and system trustworthiness in affected environments.

To mitigate CVE-2024-44159, organizations should promptly apply the official patches released by Apple in macOS Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1. Beyond patching, administrators should enforce strict application whitelisting and limit installation of untrusted software to reduce the risk of local exploitation. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local activity that attempts to access or modify privacy-protected resources. Regularly audit privacy preference settings and system logs for anomalies. Use macOS security features such as System Integrity Protection (SIP) and ensure they are enabled and up to date. Educate users about the risks of running unverified applications and maintain least privilege principles for user accounts. In high-security environments, consider network segmentation and device management policies to restrict local access to macOS systems. Finally, maintain an up-to-date inventory of macOS versions deployed to ensure timely patch management.
