齐博CMS 二次注入

漏洞作者: Power

shop\join.php中

if($action=="postnew")
{
	//自定义字段的合法检查与数据处理

	$Module_db->checkpost($field_db,$postdb,'');//跟踪
	join_post();   
	unset($id_array);

checkpost()函数中

function checkpost($field_db,&$postdb,$rsdb=''){
	foreach($field_db AS $key=>$rs)
	{
.................省略
		else
		{
			if(is_array($postdb[$key])){			
				$postdb[$key]='/#/'.implode("/#/",$postdb[$key]).'/#/';
			}
			//过滤不安全的字符
			$postdb[$key]=filtrate($postdb[$key]);//对传递过来的数据进行过滤
		}
		if(strlen($postdb[$key])>30000){
			showerr("内容不能大于1.5万个汉字");
		}
	}
}

上面的我无法利用,但是在shop//member/address.php中

elseif($action=="postnew"){
	$db->query("INSERT INTO `{$_pre}address` (`uid` ,`order_username` ,`order_phone` ,`order_mobphone` ,`order_email` ,`order_qq` ,`order_postcode` ,`order_address` ) VALUES ('$lfjuid', '$order_username', '$order_phone', '$order_mobphone', '$order_email', '$order_qq', '$order_postcode', '$order_address')");//直接转义之后入库
	refreshto("?job=list",'',0);
}elseif($action=="edit"){
	checkrid($rid);
	$db->query("UPDATE `{$_pre}address` SET order_username='$order_username',order_phone='$order_phone',order_email='$order_email',order_qq='$order_qq',order_postcode='$order_postcode',order_address='$order_address',order_mobphone='$order_mobphone' WHERE rid='$rid'");//转移后入库
	refreshto("?job=list",'',0);
}

在shop\join.php中

if($action=="postnew")
{
	//自定义字段的合法检查与数据处理

	$Module_db->checkpost($field_db,$postdb,'');
	join_post();//跟踪

join_post()函数中

function join_post(){
	extract($GLOBALS);
	global $postdb,$listdb;
	if(!table_field("{$_pre}join",'products')){
		$db->query("ALTER TABLE `{$_pre}join` ADD `products` TEXT NOT NULL ;");
	}
	$query = $db->query("SELECT * FROM {$_pre}content WHERE id IN (".implode(',',$_ar).")");
	while($rs = $db->fetch_array($query)){
		$rs[price] = str_replace(',','',$rs[price]);
		$listdb[$rs[uid]][] = $rs;
/* 		var_dump($listdb);
		exit; */
	}

	if($postdb[address_type]>0){
		$ts = $db->get_one("SELECT * FROM `{$_pre}address` WHERE uid='$lfjuid' AND rid='$postdb[address_type]'");     //数据出库
		$postdb[order_username] = $ts[order_username];
		$postdb[order_phone] = $ts[order_phone];
		$postdb[order_mobphone] = $ts[order_mobphone];
		$postdb[order_email] = $ts[order_email];
		$postdb[order_qq] = $ts[order_qq];
		$postdb[order_postcode] = $ts[order_postcode];
		$postdb[order_address] = $ts[order_address];
	}elseif($postdb[address_type]=='-1'){	
		$db->query("INSERT INTO `{$_pre}address` ( `uid` , `order_username` , `order_phone` , `order_mobphone` , `order_email` , `order_qq` , `order_postcode` , `order_address` ) VALUES ('$lfjuid' , '$postdb[order_username]' , '$postdb[order_phone]' , '$postdb[order_mobphone]' , '$postdb[order_email]' , '$postdb[order_qq]' , '$postdb[order_postcode]' , '$postdb[order_address]')");
	}
}

/shop/join.php中

if($action=="postnew")
{
	//自定义字段的合法检查与数据处理

	$Module_db->checkpost($field_db,$postdb,'');
        join_post();//此函数取出入库数据
	unset($id_array);
	foreach($listdb AS $uid=>$array){
		$totalmoney = 0;
		$detail='';
		foreach($array AS $_rs){
			$totalmoney+=$_rs[price]*$p_totalArray[$_rs[id]];
			$detail[] = "$_rs[id]={$p_totalArray[$_rs[id]]}";
		}
		$products = addslashes( implode(',',$detail) );

		$rs=$db->get_one("SELECT * FROM `{$pre}purse` WHERE uid='$uid'");
		$parray=unserialize($rs[config]);

		if($postdb[order_sendtype]==2){			//平邮
			$totalmoney+=floatval($parray[slow_send]);
		}elseif($postdb[order_sendtype]==3){	//快递
			$totalmoney+=floatval($parray[norm_send]);
		}elseif($postdb[order_sendtype]==4){	//EMS
			$totalmoney+=floatval($parray[ems_send]);
		}
		//$totalmoney = number_format($totalmoney,2);
		/*往主信息表插入内容*/
		$db->query("INSERT INTO `{$_pre}join` ( `mid` , `cid` , `cuid` ,  `posttime` ,  `uid` , `username` , `yz` , `ip` ,  `totalmoney`,`products`) 
		VALUES (
		'$mid' , '$_rs[id]' , '$uid', '$timestamp','$lfjdb[uid]','$lfjdb[username]','0','$onlineip','$totalmoney','$products')");
		$id = $id_array[] = $db->insert_id();

		unset($sqldb);
		$sqldb[]="id='$id'";
		$sqldb[]="uid='$lfjuid'";
		/*检查判断辅信息表要插入哪些字段的内容*/
		foreach( $field_db AS $key=>$value){
			isset($postdb[$key]) && $sqldb[]="`{$key}`='{$postdb[$key]}'";
		}
		$sql=implode(",",$sqldb);
		$db->query("INSERT INTO `{$_pre}content_$mid` SET $sql");//数据入库产生注入

漏洞证明:

估计是我的Mysql 注册版本太低,不能报错注入,http://www.tongyuxian.com/shop/此网站躺抢

首先注册一个个人用户,访问http://www.tongyuxian.com/shop//member/address.php?job=postnew

0507464754a037c359f4aae46f11e4cfea185ae2[1]

 

然后购买商品,结算,使用存在的地址。
