Official description
Vulnerability in the Oracle Financial Services Analytical Applications Infrastructure product of Oracle Financial Services Applications (component: Infrastructure). Supported versions that are affected are 8.0.7, 8.0.8, 8.0.9, 8.1.0, 8.1.1 and 8.1.2. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Financial Services Analytical Applications Infrastructure. While the vulnerability is in Oracle Financial Services Analytical Applications Infrastructure, 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 Financial Services Analytical Applications Infrastructure accessible data as well as unauthorized read access to a subset of Oracle Financial Services Analytical Applications Infrastructure accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Financial Services Analytical Applications Infrastructure. CVSS 3.1 Base Score 7.4 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L).

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- 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.
