Description
This strike exploits a vulnerability in Apple Webkit. Specifically, an attacker can craft JavaScript in such a way that a cross-origin object can be placed into the prototype chain of a regular object and trigger the invocation of a cross-origin setter. If this causes an exception it can be potentially leaked allowing access to another window's function constructor and turning it into a UXSS attack.
