CVE-2024-27888: An app may be able to modify protected parts of the file system in Apple macOS
CVE-2024-27888 is a high-severity vulnerability in Apple macOS Sonoma that allows a malicious app to modify protected parts of the file system due to a permissions issue. The vulnerability was addressed by removing vulnerable code and adding additional code-signing restrictions, specifically targeting a downgrade issue affecting Intel-based Mac computers. This flaw could enable unauthorized modification of critical system files. The issue is fixed in macOS Sonoma 14. 4, which was released on March 7, 2024. No known exploits in the wild have been reported. The CVSS score is 7. 1, indicating a high impact on confidentiality and integrity with low attack complexity but requiring local access and user interaction.
