I need a little help using the Metaphor exploit. I set up a server, downloaded all the files from git : https://github.com/NorthBit/Metaphor
But i can't figure out how it works. In the read me, it says that the attack file is index.php, but I keep getting a blank page with "Unsupported!" written on it.I tried to add the final-ua.html file, with no success. Any leads ?
