Vulnerability CVE-2023-42468
Published: 2023-09-13   Modified: 2023-09-14

Description:
The com.cutestudio.colordialer application through 2.1.8-2 for Android allows a remote attacker to initiate phone calls without user consent, because of improper export of the com.cutestudio.dialer.activities.DialerActivity component. A third-party application (without any permissions) can craft an intent targeting com.cutestudio.dialer.activities.DialerActivity via the android.intent.action.CALL action in conjunction with a tel: URI, thereby placing a phone call.
