Descriptions

Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Networking). Supported versions that are affected are Java SE: 7u301, 8u291, 11.0.11, 16.0.1; Oracle GraalVM Enterprise Edition: 20.3.2 and 21.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).

Una vulnerabilidad en el producto Java SE, Oracle GraalVM Enterprise Edition de Oracle Java SE (componente: Networking). Las versiones compatibles que están afectadas son Java SE: 7u301, 8u291, 11.0.11, 16.0.1; Oracle GraalVM Enterprise Edition: 20.3.2 y 21.1.0. Una vulnerabilidad difícil de explotar permite a un atacante no autenticado con acceso a la red por medio de múltiples protocolos comprometer a Java SE, Oracle GraalVM Enterprise Edition. Los ataques con éxito requieren una interacción humana de una persona diferente del atacante. Los ataques con éxito de esta vulnerabilidad pueden resultar en un acceso de lectura no autorizado a un subconjunto de datos accesibles de Java SE, Oracle GraalVM Enterprise Edition. Nota: Esta vulnerabilidad se aplica a las implementaciones de Java, generalmente en clientes que ejecutan aplicaciones Java Web Start dentro del sandbox o applets de Java dentro del sandbox, que cargan y ejecutan código no confiable (por ejemplo, código que proviene de Internet) y confían en el sandbox de Java para la seguridad. Esta vulnerabilidad no se aplica a las implementaciones de Java, comúnmente en servidores, que cargan y ejecutan solo código confiable (por ejemplo, código instalado por un administrador). CVSS 3.1 Puntuación Base 3.1 (Impactos en la Confidencialidad). Vector CVSS: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N)
