Application file access via symlink path validation
Published Mar 18, 2022 · Updated Aug 3, 2024
Path validation flaw in Apple iCloud on iOS and iPadOS before 15.3 allows local users to access files via crafted symlinks. The iCloud path-validation logic accepted symlink paths without sufficient sanitization, allowing an application to traverse to files outside the intended location. Exploitation requires a malicious application running on the affected device, and the documented consequence is unauthorized file access rather than code execution or service interruption.
