Grep与web漏洞挖掘

文/SuperHei_[At]_ph4nt0m.org   2006-03-08

[a.下面的grep( )不支持-r参数,可以使用下面的格式:

grep -in "/(include/|require/)" C:/test/*.php C:/test/admin/*.php 也可以使用cygwin移植来的grep( ) b.多个关键词or模式使用|,如果使用and模式,可以使用下面的管道模式: grep -in "/select/|$aid" C:/test/read.php |grep -i "from"]

1.包含漏洞   关键词: include require C:/>grep -in "/(include/|require/)" C:/test/*.php config.php:10:include 'forbid.php'; conn.inc.php:10:include 'forbid.php'; conn.php:10:include 'forbid.php'; global.php:10:include 'forbid.php'; global.php:16:require_once('conn.inc.php'); global.php:17:require_once('conn.php');

2.SQL Injection

关键词: select 变量名

C:/>grep -in "/select" C:/test/read.php 15:$query=$db->query("SELECT * FROM ".$tablepre."content WHERE aid=$aid");

C:/>grep -in "/select/|$aid" C:/test/read.php

13:$aid=$_GET['aid']; 14:$db->query("UPDATE ".$tablepre."content SET hits=hits+1 WHERE aid='$aid'"); 15:$query=$db->query("SELECT * FROM ".$tablepre."content WHERE aid=$aid");

3.CMD Injection

关键词: exec system popen passthru proc_open 等

C:/>grep -in "/(exec/|system/|popen/|passthru/|proc_open/)" C:/test/phpspy.php

413:    $a = $shell->ShellExecute($_POST['program'],$_POST['prog']); 602:            $program = isset($_POST['program']) ? $_POST['program'] : "c:/wi nnt/system32/cmd.exe"; 613:    $execfuncs = (substr(PHP_OS, 0, 3) == 'WIN') ? array('system'=>'system', 'passthru'=>'passthru','exec'=>'exec','shell_exec'=>'shell_exec','popen'=>'popen ','wscript'=>'Wscript.Shell') : array('system'=>'system','passthru'=>'passthru', 'exec'=>'exec','shell_exec'=>'shell_exec','popen'=>'popen'); 615:    $tb->tdbody('选择执行函数: '.$tb->makeselect(array('name'=>'execfunc','o ption'=>$execfuncs,'selected'=>$execfunc)).' 输入命令: '.$tb->makeinput('command ',$_POST['command'],'','text','60').' '.$tb->makeinput('','Run','','submit')); 620:            if ($execfunc=="system") { 621:                    system($_POST['command']); 622:            } elseif ($execfunc=="passthru") { 623:                    passthru($_POST['command']);

4.Code Injection

关键词:eval preg_replace

C:/>grep -in "/eval/|preg_replace" C:/test/*.php

phpspy.php:1034:                eval('$hexdtime = "' . $hexdtime . '";');

5.变量提交方式

关键词:GET POST COOKIE SERVER REQUEST

C:/>grep -in "_/GET/|POST/|COOKIE/|SERVER/|REQUEST" C:/test/list.php

13:$sid=$_GET['sid']; 14:if($_GET['page']) { 15:     $page=$_GET['page'];

6.cookie和session

关键词: cookie session

C:/>grep -in "/session/|cookie" C:/test/admin/*.php

global.php:16:if(!isset($_COOKIE['IN'])) { index.php:13:if(!isset($_COOKIE['IN'])) { job.php:13:if(!isset($_COOKIE['IN'])) { login.php:22:           setcookie("IN","$admin"); logout.php:11:setcookie("IN",""); main.php:14:isset($_COOKIE) ? $ifcookie="SUCCESS" : $ifcookie="FAIL";

7.文件函数

关键词:readfile fopen upload copy opendir fwrite unlink 等

........

希望大家继续! :)
