CVE-2021-0568

Local privilege escalation via unprotected profile broadcasts

Published Jun 22, 2021 · Updated Aug 3, 2024

Missing authorization in Android 11 Framework allows local users to enable disabled profiles through unprotected broadcasts. DevicePolicyManagerService.onReceive accepts ACTION_PROFILE_OFF_DEADLINE and ACTION_TURN_PROFILE_ON_NOTIFICATION broadcasts because the manifest does not restrict them to the system. A low-privileged app can trigger the transition without user interaction, allowing its user to regain access to a disabled profile.
