CVE-2025-24170 is a logic flaw in Apple macOS related to improper file handling that enables a local application to escalate its privileges to root. The vulnerability stems from a failure to correctly manage file operations, allowing an attacker-controlled app to bypass normal security checks and gain full administrative control over the system. This issue affects macOS versions prior to 14.7.5 (Sonoma) and 13.7.5 (Ventura), where Apple has implemented fixes to address the underlying logic error. Exploitation requires local access and user interaction, such as running a malicious app, but does not require any prior privileges, making it accessible to any user with the ability to execute code on the machine. The vulnerability is classified under CWE-276 (Incorrect Default Permissions), indicating that the root cause involves improper permission settings or handling that lead to privilege escalation. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. No public exploits have been reported yet, but the potential for abuse is significant given the widespread use of macOS in both consumer and enterprise environments. The flaw could be leveraged by attackers to install persistent malware, steal sensitive data, or disrupt system operations. Apple’s patches close the vulnerability by improving file handling logic and enforcing stricter permission checks. Organizations running affected macOS versions should prioritize deploying these updates to mitigate risk.

The impact of CVE-2025-24170 is substantial as it allows an unprivileged local application to gain root privileges, effectively granting full control over the affected macOS system. This can lead to complete compromise of confidentiality, enabling attackers to access sensitive user data, credentials, and system secrets. Integrity is also at risk since attackers can modify system files, install persistent malware, or alter security configurations. Availability may be affected if attackers disrupt system services or cause system instability. For organizations, this vulnerability could facilitate lateral movement within networks, data exfiltration, and sabotage of critical infrastructure. The ease of exploitation—requiring only local access and user interaction—means that social engineering or malicious insiders could trigger the attack. Although no known exploits are currently in the wild, the high severity and potential for damage make this a critical concern for enterprises, government agencies, and individual users relying on macOS for secure operations.

To mitigate CVE-2025-24170, organizations and users should immediately apply the official Apple security updates macOS Sonoma 14.7.5 and macOS Ventura 13.7.5 or later, which contain the necessary fixes. Beyond patching, restrict installation of applications to trusted sources such as the Apple App Store or verified developers to reduce risk of malicious apps. Employ endpoint detection and response (EDR) solutions capable of monitoring for unusual privilege escalation attempts and suspicious file handling behaviors. Regularly audit file permissions and system logs to detect anomalies indicative of exploitation attempts. Implement strict user privilege management, limiting local user rights where possible to reduce the attack surface. Educate users about the risks of running untrusted applications and the importance of applying system updates promptly. For high-security environments, consider application whitelisting and sandboxing to contain potential exploits. Maintain robust backup and recovery procedures to minimize impact in case of compromise.
