Sensitive information disclosure via unrestricted Android broadcast
Published Oct 7, 2022 · Updated Aug 3, 2024
Improper access control in SmartThings before 1.7.89.0 allows local attackers to read sensitive information through an Android broadcast. cloudNotificationManager.java exposes data through the PUSH_MESSAGE_RECEIVED broadcast without restricting access to authorized recipients. No privileges or user interaction are required, but an attacker must execute code locally on the Android device; the disclosed impact is limited to reading unspecified sensitive information.
