CVE-2023-42469Public exploit

Unauthorized calls via exported DialerActivity

Published Sep 13, 2023 · Updated Sep 25, 2024

Improper access control in Full Dialer 1.0.1 and earlier for Android allows local users to place calls via a crafted intent. The exported DialerActivity accepts CALL actions and tel data from installed applications without validating the caller or requiring permission. Any installed application can therefore initiate a phone call without user interaction, using the dialer's telephony authority.
