Grep与web漏洞挖掘+一款WIN下的GREP软件

a.下面的grep(http://www.interlog.com/~tcharron/grep.html)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(http://zhouzhen.eviloctal.org/Look.asp?LogID=814)

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! :)
