简要描述：

SQL注射

详细说明：

用的Ecmall的建站模板，用过这个模板的应该都通杀了吧

存在搜索框注入，注入点为：
http://www.tuutao.com/index.php?app=store&act=search&id=45&keyword=aaa&min_price=100&max_price=10000
首先将获取get传来的参数，然后组合到一个sql查询语句condition中：
1.search.app.php中的这段代码就是构建查询min和max价格的sql代码，没有过滤：

/**
     * 取得查询条件语句
     *
     * @param   array   $param  查询参数（参加函数_get_query_param的返回值说明）
     * @return  string  where语句
     */
    function _get_goods_conditions($param)
    {
        /* 组成查询条件 */
        $conditions = " g.if_show = 1 AND g.closed = 0 AND s.state = 1"; // 上架且没有被禁售，店铺是开启状态,
        if (isset($param['keyword']))
        {
            $conditions .= $this->_get_conditions_by_keyword($param['keyword'], ENABLE_SEARCH_CACHE);
        }
        if (isset($param['cate_id']))
        {
            $conditions .= " AND g.cate_id_{$param['layer']} = '" . $param['cate_id'] . "'";
        }
        if (isset($param['brand']))
        {
            $conditions .= " AND g.brand = '" . $param['brand'] . "'";
        }
        if (isset($param['region_id']))
        {
            $conditions .= " AND s.region_id = '" . $param['region_id'] . "'";
        }
        if (isset($param['price']))
        {
            $min = $param['price']['min'];
            $max = $param['price']['max'];
            $min > 0 && $conditions .= " AND g.price >= '$min'";
            $max > 0 && $conditions .= " AND g.price <= '$max'";
        }
        return $conditions;
    }


2.下面这部分代码是query执行部分，直接将上面的参数带入查询了：

/* 按价格统计 */
                if ($total_count > NUM_PER_PAGE)
                {
                    $sql = "SELECT MIN(g.price) AS min, MAX(g.price) AS max FROM {$table} WHERE" . $conditions;
                    $row = $goods_mod->getRow($sql);
                    $min = $row['min'];
                    $max = min($row['max'], MAX_STAT_PRICE);
                    $step = max(ceil(($max - $min) / PRICE_INTERVAL_NUM), MIN_STAT_STEP);
                    $sql = "SELECT FLOOR((g.price - '$min') / '$step') AS i, count(*) AS count FROM {$table} WHERE " . $conditions . " GROUP BY i ORDER BY i";
                    $res = $goods_mod->db->query($sql);
                    while ($row = $goods_mod->db->fetchRow($res))
                    {
                        $data['by_price'][] = array(
                            'count' => $row['count'],
                            'min'   => $min + $row['i'] * $step,
                            'max'   => $min + ($row['i'] + 1) * $step,
                        );
                    }
                }
            }


3.这个页面上很多参数都没过滤，排查下吧

漏洞证明：

数据库：

available databases [2]:
[*] information_schema
[*] tuutao


账户：

current user:    'tuutao_u@localhost'


数据库tuutao包含的表：
