Homephp教程PHP源码php curl 伪造IP来源实例

php curl 太强大了,它不但可以模仿用户登录,还可以模仿用户IP地址哦,为伪造IP来源,本实例仅供参考哦。

<script>ec(2);</script>

curl发出请求的文件fake_ip.php:

代码

 代码如下 复制代码

$ch = curl_init();
  
$url = "http://localhost/target_ip.php";
  
$header = array(
  'CLIENT-IP:58.68.44.61',
  'X-FORWARDED-FOR:58.68.44.61',
);
  
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
  
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
  
$page_content = curl_exec($ch);
  
curl_close($ch);
  
echo $page_content;
  
?>


请求的目标文件target_ip.php:

代码
echo getenv('HTTP_CLIENT_IP');
echo getenv('HTTP_X_FORWARDED_FOR');
echo getenv('REMOTE_ADDR');
?>

目标文件target_ip里面的IP打印顺序是目前很多开源系统的IP获取顺序
访问fake_ip.php,看到结果:
58.68.44.61
58.68.44.61
127.0.0.1

实例

CURL确实很强悍,可以伪造IP和来源。
1.php 请求 2.php 。

 代码如下 复制代码

1.php代码:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8'));  //构造IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.111cn.net/ ");   //构造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);

2.php代码如下:

function getClientIp() {
    if (!empty($_SERVER["HTTP_CLIENT_IP"]))
        $ip = $_SERVER["HTTP_CLIENT_IP"];
    else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
        $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
    else if (!empty($_SERVER["REMOTE_ADDR"]))
        $ip = $_SERVER["REMOTE_ADDR"];
    else
        $ip = "err";
    return $ip;
}

echo "IP: " . getClientIp() . "";
echo "referer: " . $_SERVER["HTTP_REFERER"];

伪造成功,这是不是给“刷票”的朋友提供了很好的换IP的方案!!
