### 简要描述：
TinyShop Sql Injection 1（无视GPC）
### 详细说明：
后台登陆界面存在检查功能，不安全取值导致的SQL注入。
```
/controller/controller_class.php
public function check()
{
$this->safebox = Safebox::getInstance();
$this->title='后台登录';
$code = $this->safebox->get($this->captchaKey);
if($code != strtolower(Req::args($this->captchaKey)))
{
$this->msg='验证码错误！';
$this->layout = "";
$this->redirect('login',false);
}
else
{
$manager = new Manager(Req::args('name'),Req::args('password'));
$this->msg='验证码错误！';
if($manager->getStatus() == 'online')
{
$back = Req::args('callback');
$model = new Model("manager");
$model->data(array('last_ip'=>Chips::getIP(),'last_login'=>date("Y-m-d H:i:s")))->where("id=".$manager->id)->update();
//这里有一个getIP函数，跟入。
if($back === null) $back = $this->defaultAction;
$this->redirect($back,true);
}
else
{
$this->msg='用户名或者密码错误';
$this->layout = "";
$this->redirect('login',false);
}
}
}
```
getip函数跟进。
/framework/lib/util/chips_class.php
public static function getIP()
{
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"]))$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
elseif (isset($_SERVER["HTTP_CLIENT_IP"])) $ip = $_SERVER["HTTP_CLIENT_IP"];
elseif (isset($_SERVER["REMOTE_ADDR"])) $ip = $_SERVER["REMOTE_ADDR"];
elseif (getenv("HTTP_X_FORWARDED_FOR")) $ip = getenv("HTTP_X_FORWARDED_FOR");
elseif (getenv("HTTP_CLIENT_IP")) $ip = getenv("HTTP_CLIENT_IP");
elseif (getenv("REMOTE_ADDR")) $ip = getenv("REMOTE_ADDR");
else $ip = "Unknown";
return $ip;
}
直接获取了$_SERVER["HTTP_X_FORWARDED_FOR"]，gpc也没用了。导致了注入。我输出语句演示。
