CVE-2020-3869Network attack vector

Incorrect camera self-view via undisclosed logic flaw

Published Feb 27, 2020 · Updated Aug 4, 2024

A logic flaw in FaceTime before iOS and iPadOS 13.3.1 allows remote attackers in a FaceTime session to show the wrong local camera. Apple identifies the locus only as local self-view handling and has not disclosed the incorrect logic or input operation. Reaching the flaw requires an active remote FaceTime session, and the reported consequence is limited to misrepresenting the camera shown in the local preview.
