简要描述：

翼支付某站从绕过上传到任意文件下载到getshell

详细说明：

站点：http://kf.bestpay.com.cn 天翼电子商务公司客服系统
与客服MM聊天：http://kf.bestpay.com.cn/zhij/imsystem/im/im_client.jsp?queueId=1011&guestId=&sessionId=&keyword=
这里有一个文件上传：

0.jpg


从图中可以看出是存在限制的，通过截断改包，绕过上传，上传jsp文件

1.jpg


上传后有一个非常严肃的问题，没办法得到shell路径：没有返回、没有类似路径、爬不到、google没用、没找到其他类似结构的站
没办法，和客服MM聊了一会儿天，<顺便说一句客服MM态度超好，帮了很大忙><真心感谢>，让她下载了该文件，并把下载的链接发送给我

http://kf.bestpay.com.cn/zhij/imsystem/download.jsp?&msgDirection=1&path=20150129113305618_1.jsp&realFileName=1.jsp


很明显，这就是一个任意文件下载，测试一下：

http://kf.bestpay.com.cn/zhij/imsystem/download.jsp?&msgDirection=1&path=/../../download.jsp&realFileName=1.jsp

平常的渗透思路断了<请大牛教我>，只能通过下载漏洞，分析源码了<只能下载jsp、jsp等，class等后缀不能下载 - - ！>，感谢好基友小胖@subversion<小胖是一个非常棒的java、jsp开发工程师，当然也是喜欢安全的>
得到发送文件的路径：/sendfile/client/
拼接起来，得到shell：http://kf.bestpay.com.cn/zhij/imsystem/sendfile/client/20150129113305618_1.jsp 密码：jspspy
