CVE-2024-54516 is a permissions vulnerability in Apple macOS that allows an application with limited privileges to approve a launch daemon without obtaining explicit user consent. Launch daemons are background processes that run with elevated privileges and can affect system behavior and security. The root cause is a permissions issue that Apple addressed by adding stricter restrictions in macOS Sequoia 15.2 and macOS Sonoma 14.7.2. The vulnerability falls under CWE-281, which relates to improper authorization. The CVSS v3.1 base score is 3.3, reflecting low severity due to the requirement for local privileges and the lack of impact on confidentiality or availability. Exploiting this flaw could allow an attacker to escalate privileges or persist on the system by silently approving malicious launch daemons. However, no user interaction is required, and the attack scope is limited to local users with some level of access. No public exploits have been reported, and Apple has not provided patch links but has indicated the fix is included in the specified macOS versions.

The primary impact of CVE-2024-54516 is on system integrity, as unauthorized approval of launch daemons can allow malicious code to run persistently with elevated privileges. This could enable attackers to maintain persistence, execute arbitrary code, or escalate privileges on affected macOS systems. While confidentiality and availability are not directly impacted, the integrity compromise could lead to further attacks that affect these areas. Organizations relying on macOS devices, especially those with sensitive data or critical operations, may face increased risk if this vulnerability is exploited. The requirement for local access limits remote exploitation, but insider threats or malware already present on the system could leverage this flaw. The absence of known exploits reduces immediate risk, but timely patching is essential to prevent future exploitation.

To mitigate CVE-2024-54516, organizations and users should upgrade affected macOS systems to macOS Sequoia 15.2 or macOS Sonoma 14.7.2 or later, where the vulnerability is fixed. Until updates are applied, restrict local user privileges to the minimum necessary and monitor for unauthorized launch daemon approvals. Employ endpoint detection and response (EDR) solutions capable of detecting unusual launch daemon activity. Regularly audit launch daemon configurations and permissions to identify unauthorized changes. Implement strict application control policies to prevent untrusted applications from running or modifying system components. Educate users about the risks of installing untrusted software and maintain robust local access controls to limit potential exploitation vectors.
