I don't think there is an easy way to get the list of tables on the db u r
testing.
Use trial and error to try all the table names that are likely be used for
storing user information. If the application u r testing is based on an open
source software, it will be easy to get the default db schema by downloading
the application from the respective website.

Subject: MS SQL, find list of tables


Hi,

I'm doing a pen test on a IIS/MS SQL box and find a SQL Injection on it
which permit to execute some SQL command on it.

In fact I have a "select" where I can inject an "UNION something".
I'd like to use that in order to get login/passwd in the database.

I can do:
<somethin.asp?page=contact' UNION SELECT * FROM users WHERE '1'='1>
But the table users doesn't exist and I failed to guess an existing
table name :(.

I've tried:
<something.asp?page=contact' UNION SELECT * FROM MSysObjects'>
but I get
----
Microsoft OLE DB Provider for ODBC Drivers error '80040e09'

[Microsoft][ODBC Microsoft Access Driver] Record(s) cannot be read; no
read permission on 'MSysObjects'.
----

Someone has an idea ????

Regards
