0x02 漏洞描述

Apache ActiveMQ是由美国阿帕奇（Apache）软件基金会开发的开源消息中间件，支持Java消息服务、集群、Spring框架等。属于消息队列组件(消息队列组件：分布式系统中的重要组件，主要解决应用耦合、异步消息、流量削峰等)。

    此漏洞出现在Fileserver应用程序中，该漏洞的原理实际上非常简单，即文件服务器支持写入文件（但不解析JSP），同时支持移动文件（MOVE请求）。因此，我们只需要编写一个文件，然后使用移动请求将其移动到任何位置，就会导致任意文件写入漏洞。

漏洞版本:

  • ActiveMQ在5.14.0之前的版本（不包括5.14.0）

1.默认密码admin:admin登录，并且在fileserver目录使用put方法上传ry.txt冰蝎马，回显204证明上传成功（注意要加Authorization:认证参数）
