CVE-2024-37574Network attack vector

Unauthorized calls via unprotected exported activity

Published Dec 4, 2024 · Updated Dec 11, 2024

Insecure permissions in GriceMobile com.grice.call 4.5.2 allow remote attackers to place calls via a crafted Android intent. The exported com.iui.mobile.presentation.MobileActivity accepts android.intent.action.CALL intents from other applications without enforcing a caller permission or requesting user consent. A malicious application must already be installed on the Android device, but it needs no permissions or victim interaction to initiate unauthorized outbound calls.
