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,为伪造IP来源,本实例仅供参考.
curl发出请求的文件fake_ip.php,代码如下:
- <?php
- $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,代码如下:
- <?php
- 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
1.php代码如下:
- $ch = curl_init();
- curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");
- curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8'));
- curl_setopt($ch, CURLOPT_REFERER, "http://www.phpfensi.com/ "); //构造来路
- curl_setopt($ch, CURLOPT_HEADER, 1);
- $out = curl_exec($ch);
- curl_close($ch);
2.php代码如下:
- function getClientIp() {
- if (!emptyempty($_SERVER["HTTP_CLIENT_IP"]))
- $ip = $_SERVER["HTTP_CLIENT_IP"];
- else if (!emptyempty($_SERVER["HTTP_X_FORWARDED_FOR"]))
- $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
- else if (!emptyempty($_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. |
