php 伪造ip地址来源实现程序

时间：2015-01-23 来源：西部数据作者：西部数据

今天我们来做一个简单的假的ip地址访问网站,这个可以利用php curl或fsockopen来实现,有需要的同学可以参考一下方案很简单的,不过此方案不完美对第三方工具没有用.

HTTP-REFERER这个变量已经越来越不可靠了,完全就是可以伪造出来的东东.

1.php 请求 2.php 。

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.google.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,再看一下相对复杂的处理办法,PHP(前提是装了curl),PHP代码如下:

$ch = curl_init();

curl_setopt ($ch, CURLOPT_URL, "http://www.phpfensi.com");

curl_setopt ($ch, CURLOPT_REFERER, "http://www.phpfensi.com/");

curl_exec ($ch);

curl_close ($ch);

PHP(不装curl用sock),代码如下:

$server = '127.0.0.1';

$host = '127.0.0.1';

$target = '/xxx.asp';

$referer = 'http://127.0.0.1/'; // Referer

$port = 80;

$fp = fsockopen($server, $port, $errno, $errstr, 30);

if (!$fp)

{

echo "$errstr ($errno)<br />n";

}

else

{

$out = "GET $target HTTP/1.1rn";

$out .= "Host: $hostrn";

$out .= "Cookie: ASPSESSIONIDSQTBQSDA=DFCAPKLBBFICDAFMHNKIGKEGrn";

$out .= "Referer: $refererrn";

$out .= "Connection: Closernrn";

fwrite($fp, $out);

while (!feof($fp))

{

echo fgets($fp, 128);

}

fclose($fp);

}

IP也可以伪造,代码如下:

$fp = fsockopen ("192.168.0.128", 80, $errno, $errstr, 30);

if (!$fp) {

echo "$errstr ($errno)<br>n";

} else {

$msg="GET /003.php HTTP/1.0rn";

$msg.="Host: 192.168.0.128rn";

$msg.="Referer: http://www.phpfensi.comrn";

$msg.="Client-IP: 1.1.1.1rn";

$msg.="X-Forwarded-For: 1.1.1.1rn"; //主要是这里来构造IP

$msg.="Connection: Closernrn";

fputs ($fp, $msg);

while (!feof($fp)) {

echo fgets ($fp,1024);

}

fclose ($fp);

}
