Descriptions

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Security). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Kerberos to compromise Java SE, Java SE Embedded. While the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 6.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).

Vulnerabilidad en el producto Java SE, Java SE Embedded de Oracle Java SE (componente: Security). Las versiones compatibles que están afectadas son Java SE: 7u241, 8u231, 11.0.5 y 13.0.1; Java SE Embedded: 8u231. Una vulnerabilidad difícil de explotar permite a un atacante no autenticado con acceso a la red por medio de Kerberos comprometer a Java SE, Java SE Embedded. Aunque la vulnerabilidad ocurre en Java SE, Java SE Embedded, los ataques pueden afectar significativamente a productos adicionales. Los ataques con éxito de esta vulnerabilidad pueden resultar en un acceso no autorizado a datos críticos o en un acceso completo a todos los datos accesibles Java SE, Java SE Embedded. Nota: Esta vulnerabilidad se aplica a las implementaciones de Java, generalmente en clientes que ejecutan aplicaciones de Java Web Start en sandbox o applets de Java en sandbox (en Java SE versión 8), que cargan y ejecutan código no seguros (por ejemplo, código que proviene de la Internet) y dependen del sandbox de Java para la seguridad. Esta vulnerabilidad también puede ser explotada mediante el uso de la API en el componente especificado, por ejemplo, por medio de un servicio web que suministra datos a las API. CVSS 3.0 Base Score 6.8 (Impactos en la Confidencialidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).
