CVE-2025-24249 is a critical security vulnerability identified in Apple macOS that stems from a permissions issue related to sandbox restrictions. Specifically, the flaw allows an unprivileged application to determine the existence of arbitrary paths on the file system, which should normally be restricted. This capability can lead to unauthorized information disclosure, as an attacker can infer the presence or absence of sensitive files or directories, potentially facilitating further targeted attacks such as privilege escalation or data exfiltration. The vulnerability affects multiple macOS versions before the patches released in macOS Sequoia 15.4, macOS Sonoma 14.7.5, and macOS Ventura 13.7.5. The issue is classified under CWE-862 (Missing Authorization), indicating a failure to properly enforce access control. The CVSS v3.1 base score is 9.8, reflecting its critical nature, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits have been reported yet, but the vulnerability's characteristics make it highly exploitable. The fix involves additional sandbox restrictions to prevent unauthorized path existence checks by applications.

The impact of CVE-2025-24249 is significant for organizations worldwide using affected macOS versions. By allowing an application to check arbitrary file system paths without proper authorization, attackers can gather sensitive information about system configuration, installed software, user data, or security controls. This information leakage can be leveraged to craft more effective attacks, including privilege escalation, targeted malware deployment, or data theft. The vulnerability compromises confidentiality by exposing file system metadata, integrity by potentially enabling unauthorized modifications through chained exploits, and availability if exploited in conjunction with other vulnerabilities. Since exploitation requires no privileges or user interaction, the threat surface is broad, including remote or local attackers deploying malicious applications or scripts. Organizations relying on macOS for critical operations, especially in sectors like finance, government, technology, and healthcare, face increased risk of data breaches and operational disruption if unpatched.

To mitigate CVE-2025-24249, organizations should immediately apply the security updates provided by Apple in macOS Sequoia 15.4, Sonoma 14.7.5, and Ventura 13.7.5 or later. Beyond patching, organizations should enforce strict application vetting policies, restricting installation of untrusted or unsigned applications to reduce the risk of malicious apps exploiting this vulnerability. Employing endpoint detection and response (EDR) solutions capable of monitoring unusual file system access patterns can help detect exploitation attempts. Network segmentation and least privilege principles should be applied to limit the impact of compromised systems. Additionally, organizations should educate users about the risks of installing unknown software and maintain regular backups to recover from potential attacks. Continuous monitoring of threat intelligence feeds for any emerging exploits related to this CVE is also recommended.
