FCKeditor二次上传拿shell算是FCKeditor集中比较经典的了，这个二次上传前提条件是要支持aspx而且要求FckEditor/editor/filemanager/connectors/aspx/connector.aspx文件为删除。二次上传漏洞对ASPX站点来说利用比较方便，成功率也比较高，当然若是ASP的站点，支持ASPX和文件为删的情况下也是没问题的。

在利用二次上传过程中我们往往都是找到FckEditor中的一些test上传页面来进行上传，不过也有遇到test上传页面全部被删除的情况，之前我便遇见过许多，不过在遇到test上传页面被删除的情况下我们可以本地构造上传页谈后提交，前提要确认FckEditor/editor/filemanager/connectors/aspx/connector.aspx文件存在，并且服务器支持ASPX的解析。

利用代码：
