CVE-2024-27871

Vulnerability

Overview CVE-2024-27871 is a path handling issue in Apple iOS, iPadOS, and macOS that could allow a malicious application to access protected user data. The root cause lies in inadequate validation of file paths, potentially enabling an app to bypass security boundaries and read sensitive information it should not have access to [1][4].

Exploitation and

Attack Surface To exploit this vulnerability, an attacker would need to have a malicious application installed on a vulnerable device. No additional network position or special privileges are required beyond app installation. The attack surface is local, meaning the app must be running on the target device. The vulnerability does not require user interaction after installation, making it a risk for users who unknowingly install malicious apps from the App Store or other sources [1][2].

Impact

If successfully exploited, a malicious application could access protected user data, such as personal documents, photos, or other private information stored in sandboxed areas of the filesystem. This could lead to privacy breaches and further compromise of the user's data [1][4].

Mitigation

Apple has addressed the issue with improved path validation in iOS 17.6, iPadOS 17.6, and macOS Sonoma 14.6, released on July 29, 2024. Users should update their devices to these versions to mitigate the risk. There are no workarounds documented; applying the security update is the recommended action [1][2][3][4].
