Easily exploitable vulnerability allows high privileged attacker having DBA privilege with network access via Oracle Net to compromise Oracle Database Sharding.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Database Sharding.
