CVE-2024-54533 is a vulnerability in Apple macOS arising from a permissions issue related to sandboxing mechanisms. Sandboxing is a security feature designed to isolate applications and restrict their access to system resources and user data. This vulnerability allows a malicious or compromised app to bypass these sandbox restrictions and access sensitive user data that should otherwise be protected. The issue was identified and addressed by Apple through additional sandbox restrictions implemented in macOS Sequoia 15.2, Sonoma 14.7.5, and Ventura 13.7.5. The CVSS v3.1 score of 7.0 reflects a high severity, with an attack vector of network (AV:N), high attack complexity (AC:H), no privileges required (PR:N), and no user interaction needed (UI:N). The scope is unchanged (S:U), with low confidentiality impact (C:L), high integrity impact (I:H), and low availability impact (A:L). The vulnerability is categorized under CWE-284 (Improper Access Control), indicating that the app can improperly access resources it should not. Although no known exploits are reported in the wild, the potential for unauthorized data access poses a significant risk. The vulnerability affects all macOS versions prior to the patched releases, and organizations running these versions should apply updates promptly to prevent exploitation.

The primary impact of CVE-2024-54533 is unauthorized access to sensitive user data by malicious applications, which can lead to data leakage and compromise of user privacy. The high integrity impact suggests that attackers could manipulate or corrupt data, potentially affecting system or application behavior. The low availability impact indicates limited disruption to system availability but does not eliminate the risk of denial-of-service conditions in some scenarios. For organizations, this vulnerability could result in exposure of confidential information, intellectual property theft, or unauthorized modification of critical data. This is particularly concerning for enterprises handling sensitive customer data, intellectual property, or operating in regulated industries such as finance, healthcare, and government. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the risk of automated or remote attacks. Although no exploits are currently known, the vulnerability's presence in widely used macOS versions means that threat actors may develop exploits, increasing the urgency for mitigation.

Organizations should immediately verify their macOS versions and prioritize upgrading to macOS Sequoia 15.2, Sonoma 14.7.5, or Ventura 13.7.5 where the vulnerability is patched. Until patching is complete, restrict installation of untrusted or unsigned applications to reduce exposure to malicious apps exploiting this vulnerability. Employ endpoint protection solutions capable of monitoring and restricting application behaviors that attempt to bypass sandbox restrictions. Implement strict application whitelisting and use Apple's built-in security features such as System Integrity Protection (SIP) and Gatekeeper to limit app permissions. Regularly audit installed applications and remove unnecessary or outdated software that could be exploited. Monitor system logs for unusual access patterns or attempts to access sensitive data by unauthorized processes. Educate users about the risks of installing unverified software and enforce policies to prevent unauthorized software installation. For high-risk environments, consider network segmentation and additional data encryption to protect sensitive information even if accessed improperly.
