Hello world 🙂 , I really hope you guys are doing great . Its been a long time , i could not post stuff .

The vulnerable url was

Its always a tricky cum technical part, how you extract content from the vulnerable page/domain by exploiting a clickjacking vulnerability . So , to exploit this vulnerability i used the research of Mr. Rafay Baloch on Android Browser Same Origin Policy Bypass < 4.4 . This research confirms the SOP ( Same Origin Policy ) bypass in Android Browsers < 4.4 version . I would like to thank Mr Rafay for the permission to use his research in this exploit building .
I made the final webpage which contains the following code

All you need to do is send the above crafted webpage url to the victim , No user interaction required . Once the victim open the page on their vulnerable android browser , it will send their cookies to the remote url and redirect the user to google .
I have made a Video POC with all the explanation

I would like to thank Eduardo from Google for handling the report and yea it was really nice to meet you and all other respected seniors of google security team members ( Michele , Josh , Chris , Kotowicz ) at NullCon .

Thank you so much google for the reward
