Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle HRMS (UK).  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle HRMS (UK), attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Oracle HRMS (UK) accessible data as well as  unauthorized read access to a subset of Oracle HRMS (UK) accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts).
