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
