Injecting a user account into mySQL - mysql

Question

Tackling a strange scenario here.
We use a proprietary workstation management application which uses mySQL to store its data. Within the application they provide number of reports, such as which user logged into which machine at what time, all the software products installed on the monitored machines, so on and so forth. We are looking to do a different set of reports, however, they do not support custom reports.
Since their data is being stored in mySQL, I gather I can do the reporting manually. I don't have valid credentials to connect to the mySQL server though. Is there anyway for me to create a user account in the mySQL server? I do not want to reset the root password or anything account that might be in there, as it might break the application.
I have full access to the Windows 2003 server. I can stop and restart services, including the mySQL server. To the actual mySQL server, I only have basic access through the GUI provided by the software. I can't connect to it directly through CLI or through another tool (due to the lack of credentials).
I apologize if it came off as if I'm trying to get unauthorized access to the mySQL server. I have contacted the software company, and as of today it's been two weeks without a response from them. I need to get to the data. I have full access to the physical box, I have admin privileges on it.

Answer 1

You'll want to use the MySQL password recovery process. Follow these instructions, except replace the password reset query with a query to add a new user. The new user query would be something like:
GRANT ALL ON *.* TO 'myuser'#'localhost' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
That will create a new user "myuser" with the password "mypassword", who may log in to MySQL through the local system's CLI. You can then use the MySQL Administrator GUI (download here) and update user permissions so you can log in from other systems on the network. Or use the GRANT statement from the CLI, if that's more your style.

Answer 2

Do you have access to the MySQL server in question?
As in, what access do you have beyond what a regular user would? You should try to go through those routes before you "hack" your way in there, since that may or may not be feasible with that software.

Answer 3

odds are there are triggers on the database side keeping a log so when you hack yourself into the database they will know when and how you did it. Not a good idea.

Answer 4

I assume I really should not answer this one, but it's just too much fun.
Look at This page about SQL injections. That should cover your needs.
This page shows how to add user accounts to mySQL
I would try entering the following in random user input fields:
p'; INSERT INTO user VALUES
('localhost','myNewAdmin',PASSWORD('some_pass'),
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
and then
p'; FLUSH PRIVILEGES;
p'; is intended to close the regular question. e.g -
Normal question is:
"Select Adress from cusomers where custName = ' + $INPUT + ';
becomes
Select Adress from cusomers where custName = 'p'; INSERT INTO user
VALUES('localhost','myNewAdmin',PASSWORD('some_pass'),
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');

One thing that comes in mind is sniffing the database communication and hope it's not encrypted. If it is encrypted try changing the configuration not to use SSL and restart mysql. A good sniffer that I use is Wireshark
From mysql 5.0 documentation:
MySQL supports secure (encrypted)
connections between MySQL clients and
the server using the Secure Sockets
Layer (SSL) protocol. This section
discusses how to use SSL connections.
It also describes a way to set up SSH
on Windows. For information on how to
require users to use SSL connections,
see the discussion of the REQUIRE
clause of the GRANT statement in
Section 12.5.1.3, “GRANT Syntax”.
The standard configuration of MySQL is
intended to be as fast as possible, so
encrypted connections are not used by
default. Doing so would make the
client/server protocol much slower.
Encrypting data is a CPU-intensive
operation that requires the computer
to do additional work and can delay
other MySQL tasks. For applications
that require the security provided by
encrypted connections, the extra
computation is warranted.
MySQL allows encryption to be enabled
on a per-connection basis. You can
choose a normal unencrypted connection
or a secure encrypted SSL connection
according the requirements of
individual applications.
Secure connections are based on the
OpenSSL API and are available through
the MySQL C API. Replication uses the
C API, so secure connections can be
used between master and slave servers.
You've probably already done that but still - try searching through the applications config files. If there's nothing - try searching through the executables/source code - maybe it's in plaintext if you're lucky.
