Apache Solr RCE(CVE-2017-12629)--vulhub

Apache Solr 远程命令执行漏洞（CVE-2017-12629）

Apache Solr 是一个开源的搜索服务器。Solr 使用 Java 语言开发，主要基于 HTTP 和 Apache Lucene 实现。原理大致是文档通过Http利用XML加到一个搜索集合中。查询该集合也是通过 http收到一个XML/JSON响应来实现。

攻击者可以通过发送HTTP POST请求到Solr的配置API，添加一个新的事件监听器，这个监听器可以配置为在Solr的某些事件发生时执行特定的命令。当Solr的特定事件发生时（如提交更改），Solr就会执行这些命令。这是一个无回显的RCE漏洞。

影响版本：Apache Solr < 7.1 Apache Lucene < 7.1
