CVE-2018-9432

Local privilege escalation via hidden Bluetooth controls

Published Nov 19, 2024 · Updated Nov 20, 2024

Permissions bypass in Android 6 through 8.1 allows local users to gain contact access through a Bluetooth permission dialog. The createPhonebookDialogView and createMapDialogView methods place the remote device name into permission text in a way that can hide the control for disabling future contact access. Exploitation requires user interaction with a phonebook or message-access prompt and bypasses the user's intended access restriction.
