CVE-2024-54547 is a vulnerability identified in Apple macOS that allows an application to access protected user data due to inadequate access control checks. The flaw is categorized under CWE-200, indicating an exposure of sensitive information to unauthorized actors. This vulnerability does not require the attacker to have privileges (PR:N), but it does require user interaction (UI:R), such as the user running or interacting with a malicious app. The attack vector is local (AV:L), meaning the attacker must have local access to the system. The vulnerability affects multiple macOS versions before the patches introduced in macOS Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2. The CVSS v3.1 base score is 5.5, reflecting a medium severity, with a high impact on confidentiality (C:H), but no impact on integrity (I:N) or availability (A:N). The vulnerability was addressed by Apple through improved access checks that prevent unauthorized apps from reading protected user data. There are no known exploits in the wild at the time of publication, but the potential for sensitive data exposure makes this a significant concern for users and organizations relying on macOS environments.

The primary impact of CVE-2024-54547 is the unauthorized disclosure of protected user data, which can lead to privacy violations, leakage of sensitive personal or corporate information, and potential compliance issues for organizations handling regulated data. Since the vulnerability does not affect data integrity or system availability, it does not enable data manipulation or denial of service. However, the exposure of confidential information can facilitate further attacks such as social engineering, identity theft, or targeted phishing campaigns. Organizations with macOS endpoints, especially those in sectors like finance, healthcare, and government, face increased risk of data breaches if systems remain unpatched. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk in environments where users may inadvertently run malicious applications. The absence of known exploits reduces immediate threat but does not preclude future exploitation attempts.

To mitigate CVE-2024-54547, organizations 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, organizations should enforce strict application control policies to prevent installation or execution of untrusted or unsigned applications. User education is critical to reduce the risk of social engineering that could lead to running malicious apps. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual access patterns to protected data. Regularly audit and restrict local user privileges to minimize the attack surface. Implement data loss prevention (DLP) mechanisms to detect and block unauthorized data access or exfiltration attempts. Maintain up-to-date inventories of macOS devices and ensure compliance with patch management policies. Finally, monitor threat intelligence sources for any emerging exploits targeting this vulnerability.
