本次两台虚拟机都采用桥接模式,保证在同一局域网内。
查看该靶机开放了哪些端口:nmap -sS -Pn 192.168.0.108

对WordPress的后台进行一些弱口令的测试
发现用户名就是admin,但是需要密码。暂时先放一放。
使用msf,利用irc的后门漏洞
但是该漏洞利用失败。另寻方法。
发现三个目录
deets.txt文件
Wp-config.php 里面定义了一些账号密码,看到Admin,让我想起了WordPress后台,这是可能是后台或者数据库的账号密码。
没想到root的密码居然也是12345,提权成功。

然后随意访问不存在的网页(404页面),获取反弹shell
python -c 'import pty;pty.spawn("/bin/bash")';
一共用了两种方法,最终都可以获取到flag。
