CVE-2024-27882

Vulnerability

Overview CVE-2024-27882 is a permissions issue in macOS that allows an application to modify protected parts of the file system. The root cause is insufficient restriction on file system access, enabling a malicious app to bypass standard macOS protections. Apple addressed the issue by adding additional restrictions, as noted in the security advisories for macOS Monterey 12.7.6, macOS Ventura 13.6.8, and macOS Sonoma 14.6 [1][4].

Exploitation

To exploit this vulnerability, an attacker would need to have an app installed on the target system that can take advantage of the insufficient permissions. No elevated privileges or user interaction beyond installing the app are explicitly required based on the advisory. The attack vector is local, as the app runs on the same device [1].

Impact

Successful exploitation allows a malicious application to modify protected parts of the file system, potentially altering system files, other applications' data, or user data that should be protected. This could lead to data corruption, privilege escalation, or other unauthorized actions [1][4].

Mitigation

Apple has released patches for all affected macOS versions: Monterey 12.7.6, Ventura 13.6.8, and Sonoma 14.6. Users should update to these versions immediately to remediate the vulnerability. There is no known workaround, and Apple does not disclose attack indicators [1].
