CVE-2023-42550

Arbitrary file access via implicit intent

Published Nov 7, 2023 · Updated Sep 12, 2024

Implicit-intent misuse in startSignIn in Samsung Account before 14.5.00.7 allows attackers to access arbitrary files under app privileges. The flow sends sensitive communication through an implicit Android intent instead of restricting delivery to an explicit component, enabling an untrusted app to receive the request and its delegated file access. Exploitation requires local placement of an attacker-controlled app and user interaction; exposure is limited to files reachable with Samsung Account privileges.
