Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Applications DBA executes to compromise Applications DBA.  Successful attacks of this vulnerability can result in  unauthorized creation, deletion or modification access to critical data or all Applications DBA accessible data as well as  unauthorized access to critical data or complete access to all Applications DBA accessible data.
