Official description
Vulnerability in the Oracle Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Event Management). The supported version that is affected is 13.5.0.0. Easily exploitable vulnerability allows high privileged attacker with access to the physical communication segment attached to the hardware where the Oracle Enterprise Manager Base Platform executes to compromise Oracle Enterprise Manager Base Platform. While the vulnerability is in Oracle Enterprise Manager Base Platform, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Enterprise Manager Base Platform accessible data as well as unauthorized access to critical data or complete access to all Oracle Enterprise Manager Base Platform accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Enterprise Manager Base Platform. CVSS 3.1 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/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.
