Supported versions that are affected are 12.2.1.4.0 and  14.1.2.1.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Identity Manager executes to compromise Oracle Identity Manager.  Successful attacks of this vulnerability can result in  unauthorized access to critical data or complete access to all Oracle Identity Manager accessible data.
