Local privilege escalation via unchecked contact URI
Published Sep 11, 2023 · Updated Sep 26, 2024
Local privilege escalation in Android 11, 12, 12L, and 13 allows local users to import contacts belonging to another user. Telephony settings activities accept a GET_CONTENT result URI from any app and use the service's cross-user permission without verifying that the URI belongs to the current user. A local app can exploit the privileged service without user interaction, cross an Android user boundary, and access another user's contact data.
