Vulnerability in the Oracle Health Sciences InForm product of Oracle Health Sciences Applications (component: Core). Supported versions that are affected are Prior to 6.3.1.3 and Prior to 7.0.0.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Health Sciences InForm. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Health Sciences InForm accessible data as well as unauthorized access to critical data or complete access to all Oracle Health Sciences InForm accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Health Sciences InForm. CVSS 3.1 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L).
