CVE-2024-54489 is a vulnerability identified in Apple macOS involving a path handling flaw in the mount command utility. The mount command is used to attach file systems to the directory tree, and improper validation of input paths can lead to path traversal issues (CWE-22). This vulnerability allows an attacker to craft malicious input that causes the mount command to execute arbitrary code unexpectedly. The root cause is insufficient validation of file paths, which can be exploited when a user runs the mount command with specially crafted parameters. The vulnerability affects multiple macOS versions prior to Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2, where Apple has implemented improved validation to address this issue. The CVSS v3.1 base score is 5.3, indicating a medium severity level, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and limited impacts on confidentiality (C:L), integrity (I:L), and availability (A:L). No known exploits have been reported in the wild, but the vulnerability could be leveraged by local attackers to gain code execution capabilities, potentially leading to further system compromise. The vulnerability is particularly concerning for environments where users have the ability to run mount commands, such as developer workstations, servers, or systems with multiple users. The fix involves improved path validation to prevent malicious input from triggering code execution.

The potential impact of CVE-2024-54489 includes unauthorized code execution on affected macOS systems, which could lead to partial compromise of system confidentiality, integrity, and availability. Although the attack requires local access and user interaction, an attacker with limited privileges could exploit this flaw to escalate their capabilities or execute malicious payloads. This could result in unauthorized data access, modification of system files, or disruption of system operations. Organizations relying on macOS for critical operations, development, or infrastructure management may face risks of insider threats or malware propagation if this vulnerability is exploited. The medium severity rating reflects the balance between the requirement for local access and user interaction and the potential for impactful code execution. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability details become widely known. Enterprises with large macOS deployments, especially in sectors like technology, finance, and government, could be targeted for lateral movement or privilege escalation attacks leveraging this vulnerability.

To mitigate CVE-2024-54489, organizations should promptly apply the security updates released by Apple for macOS Sequoia 15.2, Sonoma 14.7.2, and Ventura 13.7.2 or later versions. Beyond patching, restrict the ability to run mount commands to trusted users only, using macOS access controls and sudo policies to limit exposure. Implement monitoring for unusual mount command usage or unexpected process executions that could indicate exploitation attempts. Employ endpoint detection and response (EDR) solutions capable of detecting anomalous local command executions. Educate users about the risks of executing untrusted commands and scripts, emphasizing caution with mount operations. For environments with high security requirements, consider application whitelisting to prevent unauthorized binaries from executing. Regularly audit user privileges and system configurations to minimize the attack surface. Finally, maintain up-to-date backups to recover from potential compromise scenarios.
