CVE-2020-9835Network attack vector

Video disclosure via failed FaceTime pause logic

Published Jun 9, 2020 · Updated Aug 4, 2024

Logic error in FaceTime on Apple iOS before 13.5 allows remote attackers in a ringing call to keep receiving video after the user exits. The FaceTime pause-state logic fails to suspend outgoing video when the application leaves the foreground during the ringing state; Apple has not disclosed the responsible function or state transition. Reachability requires a FaceTime call that is still ringing and the user leaving the application, exposing live video to the other participant without granting data modification or device control.
