CVE-2025-24249: 
macOS vulnerability analysis and mitigation

CVE-2025-24249 is a permissions vulnerability discovered in macOS that was disclosed on March 31, 2025. The vulnerability affects multiple versions of macOS including Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5. The issue allows an application to check the existence of arbitrary paths on the file system due to insufficient sandbox restrictions (Apple Advisory, NVD).

The vulnerability stems from a permissions issue in the Installer component of macOS that was addressed by implementing additional sandbox restrictions. The issue has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a highly severe vulnerability with network access vector, low attack complexity, and no privileges or user interaction required (NVD).

The vulnerability allows a malicious application to bypass sandbox restrictions and check the existence of arbitrary paths on the file system, potentially leading to unauthorized access to sensitive file system information. This could enable attackers to map the file system structure and gather intelligence about the target system (Apple Advisory).

The vulnerability was discovered by YingQi Shi(@Mas0nShi) of DBAppSecurity's WeBin lab and Minghao Lin (@Y1nKoc). While technical details about exploitation are not publicly available, the high CVSS score suggests the vulnerability is relatively straightforward to exploit (NVD).

Apple has addressed this vulnerability by implementing additional sandbox restrictions in the affected macOS versions. Users are advised to update to macOS Ventura 13.7.5, macOS Sequoia 15.4, or macOS Sonoma 14.7.5 depending on their system version. These updates contain the necessary security fixes to prevent exploitation (Apple Advisory).
