Description

This module exploits a bug in the Android 4.0 to 4.3 com.android.settings.ChooseLockGeneric class. Any unprivileged app can exploit this vulnerability to remove the lockscreen. A logic flaw / design error exists in the settings application that allows an Intent from any application to clear the screen lock. The user may see that the Settings application has crashed, and the phone can then be unlocked by a swipe. This vulnerability was patched in Android 4.4.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
