CVE-2025-24277 is a vulnerability in Apple macOS related to a parsing issue in the handling of directory paths. Specifically, the flaw stems from insufficient validation of directory paths, which can be manipulated by a malicious application to escalate privileges improperly. This vulnerability is classified under CWE-276 (Incorrect Default Permissions) and allows an app to gain root privileges, effectively bypassing the operating system's security controls. The vulnerability affects multiple macOS versions prior to Sequoia 15.4, Sonoma 14.7.5, and Ventura 13.7.5, where the issue has been fixed by implementing improved path validation mechanisms. The CVSS v3.1 score of 7.8 reflects a high severity, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact on confidentiality, integrity, and availability is high, as root access grants full control over the system. No known exploits have been reported in the wild, but the vulnerability's nature makes it a critical concern for macOS users and organizations relying on Apple platforms.

If exploited, this vulnerability allows a malicious application to gain root privileges on macOS systems, which can lead to complete system compromise. Attackers could install persistent malware, steal sensitive data, modify system configurations, or disrupt system operations. The high impact on confidentiality, integrity, and availability means that sensitive organizational data and critical system functions could be exposed or damaged. Since the attack requires local access and user interaction, the threat is more relevant in environments where users might run untrusted applications or where insider threats exist. Organizations with macOS endpoints in enterprise environments, especially those handling sensitive information or critical infrastructure, face significant risks. The lack of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of remediation.

1. Apply the latest security updates from Apple immediately, specifically macOS Sequoia 15.4, Sonoma 14.7.5, or Ventura 13.7.5 or later versions that include the fix. 2. Restrict local user permissions and enforce the principle of least privilege to limit the ability of untrusted applications to execute. 3. Implement application whitelisting and restrict installation of software from unverified sources to reduce the risk of malicious apps running. 4. Educate users about the risks of running untrusted applications and the importance of user interaction in exploitation scenarios. 5. Employ endpoint detection and response (EDR) solutions to monitor for suspicious privilege escalation attempts. 6. Conduct regular audits of installed applications and system logs to detect anomalous behavior indicative of exploitation attempts. 7. For organizations with macOS devices, consider network segmentation and limiting local access to sensitive systems to reduce exposure.
