CVE-2017-13227

Autofill data disclosure via forged package identity

Published Nov 14, 2024 · Updated Nov 20, 2024

Information disclosure in Android 8.0 and 8.1 Autofill allows local users to obtain autofill data by forging an app package name. The Autofill server accepts the activity component embedded in an app-supplied AssistStructure without comparing it to the calling activity, allowing a forged identity to reach the selected Autofill service. A locally installed malicious app needs no additional execution privileges or user interaction, and the consequence is limited to data exposed through Autofill.
