Local exploitation of an arbitrary file rewrite vulnerability in Oracle Corp.'s Oracle Database 10g Release 2 database product allows attackers to gain elevated privileges.
The vulnerability exists in a function that allows a user with an authenticated session to create any file or rewrite any files to which the database account has access.
