INTO OUTFILE is a dangerous routine (as you've clearly demonstrated), but that privilege must be specifically granted to a user before it's possible to execute it. No sensible administrator would grant the FILE privilege to a webserver application's database acccount.Very true, but a good blackhat always keeps a good supply of ways to exploit common stupid administrator mistakes. I'd not be surprised in the least if more than 10% of the sites, some admin under time pressure to Just Fix It assigned FILE privs to get the web application back up and running.I find it's more common that they just have the application log in as MySQL root. It's foolish. It happens more frequently than you'd like to admit. Makes my app pentests easier though. ;-)
All true, but then we don't have a program flaw, we have a config flaw. If you run your web applications with root privileges on the database, you should be surprised when your app gets exploited. The question I have for the OP is whether or not he's found a true bug in mysql or simply exposed one of the millions of ways to exploit stupidity. -- Paul Schmehl, Senior Infosec Analyst As if it wasn't already obvious, my opinions are my own and not those of my employer. ******************************************* "It is as useless to argue with those who have renounced the use of reason as to administer medication to the dead."
