Descriptions

Vulnerability in the Java SE product of Oracle Java SE (component: JSSE). Supported versions that are affected are Java SE: 11.0.5 and 13.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE accessible data as well as 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 (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 4.8 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N).

Vulnerabilidad en el producto Java SE de Oracle Java SE (componente: JSSE). Las versiones compatibles que están afectadas son Java SE: 11.0.5 y 13.0.1. Una vulnerabilidad difícil de explotar permite a un atacante no autenticado con acceso a la red por medio de HTTPS comprometer a Java SE. Los ataques con éxito de esta vulnerabilidad pueden resultar en una actualización no autorizada, insertar o eliminar el acceso a algunos de los datos accesibles de Java SE, así como en un acceso de lectura no autorizado a un subconjunto de datos accesibles de Java SE. 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 confiable (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 Puntuación Base 4.8 (Impactos en la Confidencialidad e Integridad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N).
