CVE-2024-54498 is a vulnerability in Apple macOS involving improper path handling that allows an application to break out of its sandbox environment. The sandbox is a critical security mechanism that restricts applications to limited privileges and access, preventing them from affecting the broader system or accessing unauthorized data. This vulnerability arises from insufficient validation of file system paths, which can be manipulated by a malicious or compromised app to escape sandbox constraints. The flaw affects multiple macOS versions prior to the patched releases: macOS Sequoia 15.2, macOS Sonoma 14.7.2, and macOS Ventura 13.7.2. The CVSS v3.1 score of 8.8 reflects a high severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and scope change (S:C) that impacts confidentiality, integrity, and availability at a high level (C:H/I:H/A:H). Exploiting this vulnerability allows an attacker with local access to escalate privileges and potentially execute arbitrary code outside the sandbox, compromising system security. Although no active exploits are known at this time, the vulnerability’s characteristics make it a prime target for attackers seeking to bypass macOS security controls. The fix involves improved validation of path inputs to prevent manipulation that leads to sandbox escape.

The impact of CVE-2024-54498 is significant for organizations relying on macOS systems, especially those that enforce sandboxing to isolate applications and protect sensitive data. Successful exploitation can lead to privilege escalation, allowing malicious apps to access restricted system resources, user data, and potentially install persistent malware. This undermines the confidentiality, integrity, and availability of affected systems. In enterprise environments, this could facilitate lateral movement, data exfiltration, or disruption of critical services. The vulnerability also poses risks to developers and users of third-party applications that depend on sandboxing for security. Since exploitation requires only local access with low privileges and no user interaction, insider threats or malware that gains initial foothold could leverage this flaw to deepen system compromise. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of patching due to the vulnerability’s high severity and potential for impactful attacks.

To mitigate CVE-2024-54498, organizations should immediately apply the security updates provided by Apple in macOS Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2 or later. Beyond patching, organizations should implement strict application whitelisting and monitoring to detect anomalous behavior indicative of sandbox escape attempts. Employ endpoint detection and response (EDR) solutions capable of identifying privilege escalation and unauthorized access patterns. Limit local user privileges to the minimum necessary to reduce the attack surface. Conduct regular audits of installed applications and sandbox configurations to ensure compliance with security policies. For environments where patching is delayed, consider isolating vulnerable macOS systems or restricting local access to trusted users only. Educate users about the risks of installing untrusted applications that could exploit sandbox vulnerabilities. Finally, maintain up-to-date backups and incident response plans to quickly recover from potential compromises.
