CVE-2024-40801 is a permissions-related vulnerability in Apple macOS, specifically impacting versions before macOS Sequoia 15 and macOS Sonoma 14.7. The issue stems from insufficient enforcement of permission restrictions, which allows an application running with limited privileges (low privilege level) to access protected user data that should normally be inaccessible. The vulnerability does not require user interaction to be exploited, increasing the risk of silent data exposure. The CVSS v3.1 base score is 5.5, reflecting a medium severity level, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). This means an attacker with local access and limited privileges can read sensitive user data without altering system integrity or availability. Apple has fixed this issue by introducing additional permission restrictions in the latest macOS releases, effectively preventing unauthorized access by apps. No public exploits or active exploitation campaigns have been reported, but the vulnerability poses a risk to user privacy and data confidentiality if left unpatched.

The primary impact of CVE-2024-40801 is unauthorized disclosure of protected user data on affected macOS systems. Organizations relying on macOS devices for sensitive operations or handling confidential information face risks of data leakage if untrusted or malicious applications gain local access. Although exploitation requires local privileges, the lack of user interaction means malware or insider threats could silently access sensitive data. This can lead to privacy violations, intellectual property theft, or exposure of personally identifiable information (PII). Since integrity and availability are not affected, the threat is confined to confidentiality breaches. The scope is limited to macOS devices running versions prior to Sequoia 15 and Sonoma 14.7, but given the widespread use of Apple devices in enterprise and consumer environments, the potential impact is significant. Organizations in sectors such as finance, healthcare, government, and technology, where data confidentiality is paramount, are particularly at risk.

To mitigate CVE-2024-40801, organizations should promptly update all macOS devices to macOS Sequoia 15 or macOS Sonoma 14.7 or later, where the vulnerability is fixed. Beyond patching, organizations should enforce strict application control policies to limit installation and execution of untrusted or unnecessary applications, reducing the risk of local privilege exploitation. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local activity indicative of unauthorized data access. Implement least privilege principles for user accounts to minimize the number of users and processes with local access rights. Regularly audit installed applications and permissions to identify and remove potentially risky software. Additionally, educate users about the risks of installing unverified applications and the importance of applying system updates promptly. For environments where immediate patching is not feasible, consider restricting local access to macOS devices and employing disk encryption to protect data at rest.
