Local modification of protected filesystem areas
Published Sep 8, 2021 · Updated Aug 3, 2024
A logic flaw in Apple MobileInstallation before iOS 14.5, iPadOS 14.5, tvOS 14.5, and watchOS 7.4 allows local users to modify protected files. Apple identifies the locus as MobileInstallation but has not disclosed which operation applies insufficient restrictions to protected paths or files. Exploitation requires local code execution on an affected device; the documented consequence is filesystem modification, with no disclosed privilege escalation or data-reading impact.
