macOS vulnerability analysis and mitigation

CVE-2024-54495 is a security vulnerability affecting Apple's macOS operating systems, specifically macOS Sequoia 15.2 and macOS Sonoma 14.7.2. The vulnerability was discovered by Claudio Bozzato and Francesco Benvenuto of Cisco Talos, along with Arsenii Kostromin (0x3c3e). The issue was disclosed and patched on December 11, 2024, where an application could potentially modify protected parts of the file system (Apple Support, CVE).

The vulnerability stems from a permissions logic issue in the Swift component of macOS. The security flaw has been assigned a CVSS v3.1 base score of 5.5 (MEDIUM), with the following vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N. This indicates that the vulnerability requires local access and user interaction, but no privileges, and can result in high impact to integrity without affecting confidentiality or availability (NVD).

The vulnerability allows a malicious application to modify protected parts of the file system, potentially compromising system integrity. This could lead to unauthorized modifications of protected system files and directories, which could affect system security and stability (CIS Security).

Apple has addressed this vulnerability by improving permissions logic in macOS Sequoia 15.2 and macOS Sonoma 14.7.2. Users are advised to update their systems to these versions or later to mitigate the risk. The fix has been implemented through improved permissions logic mechanisms (Apple Support, Apple Support).
