THC-Orakel - Cracking Oracle Passwords Within Seconds
------------------------------------------------------------------------
SUMMARY
DETAILS
THC presents a crypto <http://www.thc.org/thc-orakel>; paper analyzing the
database authentication mechanism used by oracle. THC further releases
practical tools to sniff and crack the password of an oracle database
within seconds.
One of the network authentication modes used by Oracle databases uses a
weak key exchange mechanism. This mechanism is still used on the newest
database versions using Oracle's JAVA drivers. Also, for native Oracle
drivers an attack is known to downgrade the authentication mode to the
vulnerable version. The orakelsniffert article documents the mechanism
used by the weak authentication mode, the complexity and impact of the
attack and an example of an attack in the field. A Windows based cracker
and a simple JAVA based client application are included to verify the
results. Also, a supporting crypto utility is released.
