CVE-2025-24170 is a logic issue vulnerability in Apple macOS that allows an application to escalate privileges to root. The root cause is an improper file handling logic flaw, which can be exploited by a local attacker with user interaction to gain full administrative control over the system. This vulnerability affects macOS versions prior to Ventura 13.7.5 and Sonoma 14.7.5, where Apple has implemented fixes to improve file handling and close the privilege escalation vector. The vulnerability is classified under CWE-276 (Incorrect Default Permissions), indicating that the flaw arises from improper permission or access control logic. The CVSS v3.1 score of 7.8 reflects a high severity due to the vulnerability's impact on confidentiality, integrity, and availability, combined with low attack complexity and no required privileges before exploitation. Although no known exploits have been reported in the wild, the potential for full system compromise makes this a critical issue for macOS users. The vulnerability requires local access and user interaction, meaning an attacker must convince a user to run a malicious app or code. The flaw could be leveraged by malware or a malicious insider to gain root privileges, bypassing macOS security controls and potentially leading to persistent system compromise, data theft, or disruption of services.

The impact of CVE-2025-24170 is significant for organizations using macOS systems. Successful exploitation grants an attacker root privileges, enabling full control over the affected device. This can lead to unauthorized access to sensitive data, installation of persistent malware, disabling of security mechanisms, and disruption of system availability. Organizations relying on macOS for critical operations, development, or handling sensitive information face increased risk of data breaches and operational downtime. The vulnerability could be exploited in targeted attacks or by malware spreading laterally within networks. Since the flaw requires local access and user interaction, the threat is higher in environments where users may run untrusted applications or where endpoint security controls are weak. The broad impact on confidentiality, integrity, and availability makes this vulnerability a serious concern for enterprises, government agencies, and individuals using macOS devices.

To mitigate CVE-2025-24170, organizations and users should immediately update affected macOS systems to versions Ventura 13.7.5, Sonoma 14.7.5, or later where the vulnerability is patched. Restricting the installation and execution of untrusted or unsigned applications through macOS Gatekeeper and application whitelisting can reduce the risk of exploitation. Employ endpoint protection solutions that monitor for suspicious local privilege escalation attempts. Educate users about the risks of running unknown or unverified software to minimize user interaction exploitation vectors. Implement strict access controls and limit local user privileges where possible to reduce the attack surface. Regularly audit and monitor macOS systems for unusual activity indicative of privilege escalation attempts. In environments with high security requirements, consider additional hardening measures such as system integrity protection and mandatory access controls. Finally, maintain an incident response plan to quickly address any suspected exploitation.
