Local privilege escalation via tapjacking overlay

Published Jan 14, 2022 · Updated Aug 3, 2024

Tapjacking in Google Android Automotive OS 9 through 12 allows local users to gain additional privileges through a deceptive overlay. The flaw is in LocationSettingsActivity's AndroidManifest.xml declaration, but Google has not published the specific manifest operation that permits the overlay. Exploitation requires user interaction; successful tapjacking grants privileges beyond the attacker's existing execution rights.
