CVE-2024-23276 is a logic vulnerability in Apple macOS that allows an application to elevate its privileges due to inadequate internal checks in the operating system's privilege management mechanisms. This flaw is classified under CWE-269 (Improper Privilege Management), indicating that the system fails to enforce correct privilege boundaries. The vulnerability affects multiple macOS versions prior to the patched releases: Sonoma 14.4, Monterey 12.7.4, and Ventura 13.6.5. Exploitation does not require user interaction or prior authentication, making it particularly dangerous. An unprivileged app could leverage this flaw to gain high-level privileges, potentially leading to full system compromise, including unauthorized access to sensitive data, modification or deletion of critical files, and disruption of system availability. The CVSS v3.1 base score is 8.4, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction required. Although no active exploits have been reported, the vulnerability's characteristics make it a prime target for attackers aiming to bypass macOS security controls. Apple addressed the issue by improving internal logic checks to prevent unauthorized privilege escalation. Organizations running affected macOS versions should prioritize patching to mitigate this risk.

For European organizations, the impact of CVE-2024-23276 can be significant, especially in sectors such as finance, healthcare, government, and critical infrastructure where macOS devices are used. Successful exploitation could allow attackers to gain elevated privileges on compromised machines, leading to unauthorized access to sensitive information, installation of persistent malware, lateral movement within networks, and disruption of services. This could result in data breaches, intellectual property theft, operational downtime, and regulatory non-compliance with GDPR and other data protection laws. The vulnerability's presence in widely used macOS versions increases the attack surface. Organizations with remote or hybrid workforces using macOS devices are particularly at risk. Additionally, the lack of required user interaction simplifies exploitation, increasing the likelihood of automated or stealthy attacks. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score underscores the urgency of mitigation.

1. Immediately deploy the security updates released by Apple for macOS Sonoma 14.4, Monterey 12.7.4, and Ventura 13.6.5 to all affected systems. 2. Enforce strict application whitelisting and restrict installation of software to trusted sources to reduce the risk of malicious apps attempting exploitation. 3. Implement endpoint detection and response (EDR) solutions capable of monitoring for unusual privilege escalation behaviors and alerting security teams. 4. Conduct regular audits of user privileges and system logs to detect anomalies indicative of exploitation attempts. 5. Educate users and IT staff about the risks of privilege escalation vulnerabilities and the importance of timely patching. 6. For organizations with macOS device fleets, use mobile device management (MDM) tools to enforce patch compliance and security policies. 7. Consider network segmentation to limit the potential spread of an attacker who gains elevated privileges on a single device. 8. Maintain up-to-date backups and incident response plans to quickly recover from potential compromises.
