CVE-2022-32838

Vulnerability

A logic issue in state management within the Apple File System (APFS) component allows an app to read arbitrary files outside its sandbox. The vulnerability affects macOS Monterey before 12.5, macOS Big Sur before 11.6.8, macOS Catalina before Security Update 2022-005, iOS before 15.6, and iPadOS before 15.6 [1][2][3][4]. The issue was addressed with improved state management.

Exploitation

An attacker must have the ability to run a malicious app on the target device. No additional privileges or user interaction beyond launching the app are required. The app can exploit the logic flaw to bypass file system restrictions and read files that should be inaccessible.

Impact

Successful exploitation allows the app to read arbitrary files on the device, leading to unauthorized disclosure of sensitive information such as user data, credentials, or system files. The attacker gains file read access outside the app's sandbox.

Mitigation

Apple released fixes on July 20, 2022, in macOS Monterey 12.5, macOS Big Sur 11.6.8, Security Update 2022-005 Catalina, iOS 15.6, and iPadOS 15.6 [1][2][3][4]. Users should update to these versions or later. No workarounds are available.
