Once more I want your hep.

First of all we got an sql injectable site where passwords can be retrieved because they are in plaintext and information schema command can be used.

Now to get deeper, i know that in this site there is a db where admin info (passes etc) are stored. These passwords are md5 encrypted not plaintext like the passwords on the table i retrieved.

The thing is, i know only one table name (common guess Razz ), how i can find other tables names too?

And something more, using that:
Code:
UNION+ALL+SELECT+1,2,3,4,5,6,7,8,9,10,11,password,13,14,15,16,17,18,19,20,21,user+from+mysql.user/*


I get the output of name= root and pass= 6e5b05db3a6facba (md5?). Can these info help me go further?

Table and column names can be enumerated via information_schema, if mysql version is >= 5.x, or they must be bruteforced or guessed.
This hash you got, it's old-style mysql hash. I will try to crack it.
And by the way, as you can read mysql.user table, then you probably have FILE privileges too. Which means, that you can try to read and write local files (LOAD_FILE and INTO OUTFILE) Wink

so, seeing that in order to update a table I need an sql injetion in update querry, how can I search for update querries?

Having a form on the website which creates a user and after that you have the option to change some of your information, doesn't show us that there is an update querry behind that?
