使用方法如下:
1. 把以下代码保存为_safe.asp,然后放到站点根目录即可。
<%
On Error Resume Next
if request.querystring<>"" then call stophacker(request.querystring,"'|(alert|confirm|prompt)|<[^>]*?>|^+/v(8|9)|onmouse(over|move)=|(and|or).+?(>|<|=|in|like)|/*.+?*/|
if Request.ServerVariables("HTTP_REFERER")<>"" then call test(Request.ServerVariables("HTTP_REFERER"),"'|(and|or).+?(>|<|=|in|like)|/*.+?*/|
if request.Cookies<>"" then call stophacker(request.Cookies,"(and|or).{1,6}?(=|>|<|in|like)|/*.+?*/|
call stophacker(request.Form,"^+/v(8|9)|(and|or).{1,6}?(=|>|<|in|like)|/*.+?*/|

end function
sub slog(logs)
dim toppath,fs,Ts
toppath = Server.Mappath("/index.asp")
Set fs = CreateObject("scripting.filesystemobject")
If Not Fs.FILEEXISTS(toppath) Then
Set Ts = fs.createtextfile(toppath, True)
Ts.close
end if
Set Ts= Fs.OpenTextFile(toppath,8)
Ts.writeline (logs)
Ts.Close
Set Ts=nothing
Set fs=nothing
end sub

2.在所需要防护的页面加入代码
就可以做到页面防注入、跨站。
如果想整站防注,就在网站的一个公用文件中,如数据库链接文件conn.asp中!
添加来调用本代码,赶快去试试吧!
