一段asp防注入的通用脚本

asp防注入效果代码放在conn.asp里就行了。

'屏蔽通过地址栏攻击
url=Request.ServerVariables("QUERY_STRING")
if instr(url,";") >=1 then
url=Replace(url,";","；") : Response.Redirect("?" & url)
end if
'屏蔽通过表单攻击
for each item in request.form
stritem=lcase(server.HTMLEncode(Request.form(item)))
if instr(stritem,"select ") >=1 or instr(stritem,"insert ") >=1 or instr(stritem,"update ") >=1 or instr(stritem,"delete ") >=1 or instr(stritem,"exec ") >=1 or instr(stritem,"declare ") >=1 then
response.write ("对不起,请不要输入非法字符!")
response.end
end if
next
