Summary		(es) Vulnerabilidad en el componente Java VM del servidor de base de datos Oracle. Versiones compatibles que están afectadas son 19.3-19.31, 21.3-21.22 y 23.4.0-23.26.2. Vulnerabilidad fácilmente explotable permite a un atacante con pocos privilegios que tiene el privilegio Create Session con acceso de red a través de Oracle Net comprometer Java VM. Ataques exitosos de esta vulnerabilidad pueden resultar en acceso no autorizado de creación, eliminación o modificación a datos críticos o a todos los datos accesibles por Java VM. Puntuación base CVSS 3.1 6.5 (Impactos en la integridad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N).
