Descriptions

Vulnerability in the Java SE product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 11.0.8 and 15. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE 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 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

Vulnerabilidad en el producto Java SE de Oracle Java SE (componente: Libraries). Las versiones compatibles que están afectadas son Java SE: 11.0.8 y 15. Una vulnerabilidad explotable fácilmente permite a un atacante no autenticado con acceso a la red por medio de múltiples protocolos comprometer a Java SE. 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. Nota: Esta vulnerabilidad Aplica a las implementaciones de Java, normalmente en clientes que ejecutan aplicaciones Java Web Start en sandbox o applets de Java en sandbox, que cargan y ejecutan código que no es de confianza (por ejemplo, código que proviene de Internet) y confían en el sandbox de Java para su seguridad. Esta vulnerabilidad no aplica a las implementaciones de Java, típicamente en servidores, que cargan y ejecutan solo código confiable (por ejemplo, código instalado por un administrador). CVSS 3.1 Puntuación Base 5. 3 (Impactos de la Confidencialidad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
