虽然在20140618的防注入补丁添加了防注入代码 但是还是能勉强绕过。

在app/my_goods.app.php中


 

function edit()
     {
         $id = empty($_GET['id']) ? 0 : intval($_GET['id']);
         if (!IS_POST)
         {
             $this->assign('goods', $this->_get_goods_info($id));
 
             /* 取得商品分类 */
             $this->assign('mgcategories', $this->_get_mgcategory_options(0)); // 商城分类第一级
             $this->assign('sgcategories', $this->_get_sgcategory_options());  // 店铺分类
 
             /* 当前页面信息 */
             $this->_curlocal(LANG::get('member_center'), 'index.php?app=member',
                              LANG::get('my_goods'), 'index.php?app=my_goods',
                              LANG::get('goods_list'));
             $this->_curitem('my_goods');
             $this->_curmenu('edit_goods');
             $this->assign('page_title', Lang::get('member_center') . Lang::get('my_goods'));
 
             $this->import_resource(array('script' => 'mlselection.js,jqtreetable.js,jquery.plugins/jquery.validate.js',
                                          'style'  => 'jqtreetable.css'));
 
             /* 所见即所得编辑器 */
             $this->assign('build_editor', $this->_build_editor(array('name' => 'description')));
             $this->display('my_goods.form.html');
         }
         else
         {
             /* 取得数据 */
             $data = $this->_get_post_data($id);
 
 
             /* 检查数据 */
             if (!$this->_check_post_data($data, $id))
             {
                 $this->show_warning($this->get_error());
                 return;
             }
 
             /* 保存商品 */
             if (!$this->_save_post_data($data, $id))
             {
                 $this->show_warning($this->get_error());
                 return;
             }

跟一下这函数_save_post_data


 

function _save_post_data($data, $id = 0)
     {
         import('image.func');
         import('uploader.lib');
 
         if ($data['goods']['tags'])
         {
             $data['goods']['tags'] = $this->_format_goods_tags($data['goods']['tags']);
         }
 
         /* 保存商品 */
         if ($id > 0)
         {
             // edit
             if (!$this->_goods_mod->edit($id, $data['goods']))
             {
                 $this->_error($this->_goods_mod->get_error());
                 return false;
             }
 
             $goods_id = $id;
         }
         else
         {
             // add
             $goods_id = $this->_goods_mod->add($data['goods']);
             if (!$goods_id)
             {
                 $this->_error($this->_goods_mod->get_error());
                 return false;
             }
             if (($data['goods_file_id'] || $data['desc_file_id'] ))
             {
                 $uploadfiles = array_merge($data['goods_file_id'], $data['desc_file_id']);
                 $this->_uploadedfile_mod->edit(db_create_in($uploadfiles, 'file_id'), array('item_id' => $goods_id));
             }
             if (!empty($data['goods_file_id']))
             {
                 $this->_image_mod->edit(db_create_in($data['goods_file_id'], 'file_id'), array('goods_id' => $goods_id));
             }
         }
         /* 保存规格 */
         if ($id > 0)
         {
             /* 删除的规格 */
             $goods_specs = $this->_spec_mod->find(array(
                 'conditions' => "goods_id = '{$id}'",
                 'fields' => 'spec_id'
             ));
             $drop_spec_ids = array_diff(array_keys($goods_specs), array_keys($data['specs']));
             if (!empty($drop_spec_ids))
             {
                 $this->_spec_mod->drop($drop_spec_ids);
             }
 
         }
         $default_spec = array(); // 初始化默认规格
         foreach ($data['specs'] as $key => $spec)
         {
             if ($spec_id = $spec['spec_id']) // 更新已有规格ID
             {
                 $this->_spec_mod->edit($spec_id,$spec);
             }
             else // 新加规格ID
             {
                 $spec['goods_id'] = $goods_id;
                 $spec_id = $this->_spec_mod->add($spec);
             }
             if (empty($default_spec))
             {
                 $default_spec = array('default_spec' => $spec_id, 'price' => $spec['price']);
             }
         }
 
         /* 更新默认规格 */
         $this->_goods_mod->edit($goods_id, $default_spec);
         if ($this->_goods_mod->has_error())
         {
             $this->_error($this->_goods_mod->get_error());
             return false;
         }
 
         /* 保存商品分类 */
         $this->_goods_mod->unlinkRelation('belongs_to_gcategory', $goods_id);
         if ($data['cates'])
         {
             $this->_goods_mod->createRelation('belongs_to_gcategory', $goods_id, $data['cates']);
         }
 
         /* 设置默认图片 */
         if (isset($data['goods_file_id'][0]))
         {
             $default_image = $this->_image_mod->get(array(
                 'fields' => 'thumbnail',
                 'conditions' => "goods_id = '$goods_id' AND file_id = '{$data[goods_file_id][0]}'",
             ));
             $this->_image_mod->edit("goods_id = $goods_id", array('sort_order' => 255));
             $this->_image_mod->edit("goods_id = $goods_id AND file_id = '{$data[goods_file_id][0]}'", array('sort_order' => 1));
         }
 
         $this->_goods_mod->edit($goods_id, array(
             'default_image' => $default_image ? $default_image['thumbnail'] : '',
         ));

首先看这函数里面 


 

$default_image = $this->_image_mod->get(array(
                 'fields' => 'thumbnail',
                 'conditions' => "goods_id = '$goods_id' AND file_id = '{$data[goods_file_id][0]}'",
             ));

$default_image 这变量可以看到是从出库里面来的 看看哪里入库



首先注册一个会员发布一个商品然后如图所示


 

在图片地址那里直接写payload 虽然会被转义 但是会被入库 入库并没有重命名
 

$default_image = $this->_image_mod->get(array(
                 'fields' => 'thumbnail',
                 'conditions' => "goods_id = '$goods_id' AND file_id = '{$data[goods_file_id][0]}'",
             ));
             $this->_image_mod->edit("goods_id = $goods_id", array('sort_order' => 255));
             $this->_image_mod->edit("goods_id = $goods_id AND file_id = '{$data[goods_file_id][0]}'", array('sort_order' => 1));
         }
 
         $this->_goods_mod->edit($goods_id, array(
             'default_image' => $default_image ? $default_image['thumbnail'] : '',
         ));

可以看到$default_image 出库后 

$this->_goods_mod->edit($goods_id, array(

'default_image' => $default_image ? $default_image['thumbnail'] : '',

直接带入到了edit函数里面 造成了二次注入。



这里我们编辑这商品的时候出库 造成了注入


 

成功出数据
