Official description
Vulnerability in the Oracle Complex Maintenance, Repair and Overhaul product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.12-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Complex Maintenance, Repair and Overhaul. While the vulnerability is in Oracle Complex Maintenance, Repair and Overhaul, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Complex Maintenance, Repair and Overhaul accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Complex Maintenance, Repair and Overhaul. CVSS 3.1 Base Score 8.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L).

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
