Version: <=5.0.18

An attacker has the opportunity to bypass query logging.


In case the " log" parameter is On, server saves all  database queries in file.
Attacker can use NULL symbol in query to bypass loggin.
All data after NULL symbol will cut off and attacker's queries won't be logged.


mysql_query('/*'.chr(0).'*/ SELECT * FROM table');
