题解
vlhub给了我们这样的网页
测试发现只不能提交.php文件，我们将一句话木马<?php phpinfo(); ?>写进1.txt，重命名为1.jpg，然后上传，这个过程burp抓包，将filename从"1.jpg"改为"1.jpg "并forward，上传成功~服务器存着一个叫"1.jpg "的非图片文件.
在浏览器输入62.234.14.252:8080/uploadfiles/1.jpgaa.php并抓包，
然后Forward，漏洞利用成功：
我的服务器是nginx1.20，比较新，上述漏洞未能成功显示phpinfo();显示如下：
踩坑点及深入挖掘原理
-
成功上传1.jpg[0x20]后，访问http://62.234.14.252:8080/uploadfiles/1.jpg显示如下
因为服务器上存的是1.jpg[0x20]，而浏览器输入62.234.14.252:8080/uploadfiles/1.jpg[0x20]实际访问的还是62.234.14.252:8080/uploadfiles/1.jpg （对，浏览器会过滤忽略掉url开头结尾的空格），所以404了。

假设我们上传的就是1.jpg，文件名不带空格，然后我们访问62.234.14.252:8080/uploadfiles/1.jpg，这个访问过程无法被FoxyProxy和burp抓包，可能是因为纯图片不是报文不在其业务范围的缘故。
解决如何即访问1.jpg[0x20]又能让burp抓到包？：
访问http://62.234.14.252:8080/uploadfiles/1.jpgaa.php,违背了纯图片就能被抓包了。然后用burp在底层将aa修改为
[0x20][0x00]就能访问1.jpg[0x20]了 -
官方教程教收尾阶段访问
http://your-ip:8080/uploadfiles/1.jpg[0x20][0x00].php，我傻乎乎的尝试在浏览器输入带[]的、不带[]的、[0x20]改写而成空格的、[0x00]改写不成空，都显示404了。后来才知道要去burp去修改报文的十六进制底层，即访问http://62.234.14.252:8080/uploadfiles/1.jpgaa.php，其中aa是可以留的占位符，a在底层对应ascii的十六进制61，将[61][61]改成[20][00]，其中20是空格，00是空的ascii。 -
这里应该是用到了0x00截断原理了，具体原理是 系统在对文件名的读取时，如果遇到0x00，就会认为读取已结束。这个常用在对文件类型名的绕过上。还不止这个原理。
-
当Nginx得到一个用户请求时，首先对url进行解析，进行正则匹配，如果匹配到以.php后缀结尾的文件名（即http://62.234.14.252:8080/uploadfiles/1.jpg \0.php），会将请求的PHP文件交给PHP-CGI去解析。
其中处理模块如下：location ~ \.php$ { root html; include fastcgi_params; fastcgi_pass IP:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name; fastcgi_param DOCUMENT_ROOT /var/www/html; }
以.php结尾的文件都会交给该模块处理，其中fastcgi_pass就是Nginx与PHP-FPM之间的媒介，通过ip+port的方式将请求转发给PHP解释器。但是我们有代码的文件它叫’1.jpg ‘啊,不叫'1.php'不叫'1.jpg php'不叫'1.jpgphp'，所以我们利用0x00的阶段原理，用0x00将'1.jpg '和.php分隔开。http://62.234.14.252:8080/uploadfiles/1.jpg \0.php通过.php进入这个Location块；但进入后，Nginx却因0x00隔断而错误地认为请求的文件是
1.gif[0x20]，就将'1.gif '交付PHP-CGI去解析（就设置其为SCRIPT_FILENAME
