(CVE-2019-12409)Apache Solr JMX 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.shENABLE_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
msf5 exploit(multi/misc/java_jmx_server) > show options
