CVE-2020-0018

User input disclosure via verbose event logging

Published Feb 13, 2020 · Updated Aug 4, 2024

Information disclosure in Android 8.0, 8.1, 9, and 10 allows local users to read logged user input through InputDispatcher. MotionEntry::appendDescription in InputDispatcher.cpp includes KeyEvent and MotionEvent details in dumpsys output instead of suppressing them on user builds. System execution privileges are required, no user interaction is needed, and exposure is limited to input-event confidentiality.
