Unauthorized calls via exported DialerActivity intents
Published Jan 6, 2025 · Updated Jan 7, 2025
Improper access control in iCall OS17 - Color Phone Flash 4.3 and earlier allows attackers to place calls through crafted intents. The exported com.callos14.callscreen.colorphone.DialerActivity accepts inter-app intents from any application and initiates an outgoing call without checking caller permissions or requiring confirmation. Exploitation requires a malicious third-party application on the Android device, but that application needs no permissions and the user need not interact.
