CVE-2024-54474 is a vulnerability identified in Apple macOS operating systems that allows an application to access user-sensitive data improperly due to insufficient access control checks. The vulnerability affects macOS versions prior to Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2, where Apple has implemented improved verification mechanisms to prevent unauthorized data access. The flaw requires the attacker to have local access with limited privileges (PR:L) but does not require user interaction (UI:N), making it feasible for malicious or compromised applications already running on the system to exploit the vulnerability. The attack vector is local (AV:L), meaning remote exploitation is not possible without prior system access. The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. The CVSS 3.1 base score is 5.5, indicating a medium severity. No known exploits have been reported in the wild, suggesting limited active exploitation at this time. The vulnerability highlights the importance of strict access control enforcement in operating system components that handle sensitive user data. The patch releases address the issue by enhancing internal checks to ensure only authorized processes can access protected data.

The primary impact of CVE-2024-54474 is unauthorized disclosure of sensitive user data on affected macOS systems. This can lead to privacy violations, leakage of confidential information, and potential escalation of further attacks if sensitive credentials or personal data are exposed. Organizations relying on macOS devices for critical operations, especially those handling sensitive or regulated data, face increased risk of data breaches. Although the vulnerability requires local access and some privileges, it could be exploited by malicious insiders, compromised applications, or attackers who have gained limited foothold on the system. The lack of required user interaction lowers the barrier for exploitation once local access is obtained. However, since integrity and availability are unaffected, the threat is confined to confidentiality breaches. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation. Overall, the vulnerability poses a moderate risk to organizations with macOS endpoints, particularly in sectors like finance, healthcare, government, and technology.

Organizations should immediately apply the security updates provided by Apple in macOS Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2 to remediate this vulnerability. Beyond patching, organizations should enforce strict application control policies to limit the installation and execution of untrusted or unnecessary software on macOS devices. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local activity that could indicate attempts to exploit this vulnerability. Regularly audit user privileges and restrict local user permissions to the minimum necessary to reduce the risk of privilege abuse. Implement strong device management and security configurations via Apple’s management tools to ensure compliance with security policies. Educate users about the risks of installing unverified applications and maintain robust backup and incident response plans to mitigate potential data exposure consequences. Continuous monitoring for updates from Apple and threat intelligence sources is essential to respond promptly to any emerging exploit attempts.
