php curl 伪造IP来源的实例代码

分享下用php的curl来伪造IP地址来源的方法。

curl发出请求的文件fake_ip.php:

<?php
$ch = curl_init();
$url = "http://www.jbxue.com/ 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:

<?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：

<?
/**
* curl伪造IP来源
* by www.jbxue.com
*/

$ch = curl_init();
curl_setopt($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.jbxue.com/ "); //构造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);

2.php代码如下：

<?php
/**
* 获取客户端IP地址
* edit by www.jbxue.com
*/
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"];
?>
