Proof of concept code that demonstrates how an Oracle DB user which has been granted CREATE ANY DIRECTORY can use that system privilege to grant themselves the SYSDBA system privilege by creating a DIRECTORY pointing to the password file location on the OS and then overwriting it with a previously prepared known binary password file using UTL_FILE.PUT_RAW from within the DB.

An Oracle DB user which has been granted CREATE ANY DIRECTORY can use that system privilege to grant themselves the SYSDBA system privilege by creating a DIRECTORY pointing to the password file location on the OS and then overwriting it with a previously prepared known binary password file using UTL_FILE.PUT_RAW from within the DB. This paper will show how the issue can be exploited and most importantly how to secure against it.

New Oracle Security Paper - How to secure Oracle passwords from rainbow tables and new password cracking patches. Also includes a free audit tool called OraBrute to brute force SYS AS SYSDBA in order to check that it has been secured. Unfortunately by default it is not but can be secured by following this papers recommendations.
