Oracle Hacker Gets The Last Word

Andy Greenberg writes on Forbes.com:

In 2001, Larry Ellison brashly proclaimed in a keynote speech at the computing conference Comdex that his database software was "unbreakable." David Litchfield has devoted the last nine years to making the Oracle chief executive regret that marketing stunt.

At the Black Hat security conference Tuesday afternoon, Litchfield unveiled a new bug in Oracle's 11G database software, a critical, unpatched vulnerability that would allow a hacker to take control of an Oracle database and access or modify information at any security level. "Anything that God can do on that database, you can do," Litchfield told Forbes in an interview following his talk.

The attack that Litchfield laid out for Black Hat's audience of hackers and cybersecurity researchers exploits a combination of flaws in Oracle's software. Two sections of code within the company's database application--one that allows data to be moved between servers and another that allows management of Oracle's implementation of java--are left open to any user, rather than only to privileged administrators. Those vulnerable subroutines each have their own simple flaws that allow the user to gain complete access to the database's contents.

Litchfield says he warned Oracle about the flaws in November, but they haven't been patched. Oracle didn't immediately respond to a request for comment.
