Litchfield Oracle 11g Remote Hack is a Hoax

Oracle News by Burleson Consulting
February 5,  2015

Well-known attention hound David Litchfield is saying that the sky is falling again, this time claiming that he has discovered a new way to remotely hack an Oracle 11g database. 

His latest vulnerability would only be a problem for an reckless or incompetent DBA. somebody who leaves the default permissions and does not lock-down their environment.

David's Litchfield’s “Zero day remote hack”, recommends a workaround that revokes the default  public grants privileges from dbms_jvm_exp_perms, dbms_java and dbms_java_test. 

For Litchfield to  note that using Oracle's the out-of-the box defaults will cause an exposure is common knowledge, and it's hardly newsworthy. 

Litchfield has been chastised by Oracle Corporation many times for his nonsensical and outlandish claims, and this one is no different, it’s all nonsense.  The “exploit” he talks about is a DBA-101 issue that no qualified DBA would allow. 

At one time, Litchfield called for the resignation of the chief of Oracle security, making headlines all over the world, in a failed attempt to hurt Oracle's reputation as the world's most secure database platform. 

Aiding and abetting criminal?

In one case where David Litchfield did find a real security vulnerability, he published the exploit before Oracle could patch the problem, exposing thousands of Oracle customers.  In some jurisdictions, publishing instruction for unlawful acts is considered aiding and abetting criminal activity and this outrageous act promoted a response Oracle Corporation, about these “black hat” vulnerability research clubs:

“I find those trafficking in nonpublic exploits morally reprehensible”.
                - Mary-Ann Davidson, CTO, Oracle Corporation

Oracle Corporation says that these "black hat" vulnerability clubs are "selfish", "irresponsible", "morally reprehensible" and "dangerous", especially when they openly publishing instruction on how-to hack into Oracle databases:

"A few hours after Litchfield went public with a technical description of the flaw, including a blow-by-blow demonstration of ease in which an attack could occur, Oracle lashed back, accusing the British researcher of putting its customers at severe risk for selfish, irresponsible reasons...

Even as he downplayed the severity of the flaw, Harris said Litchfield's decision to go the way of "irresponsible disclosure" was a "dangerous thing to do."

While it’s possible that a naïve or stupid DBA might forget to lock-down their public grants, this alert does not apply to the vast majority of Oracle shops.
