Descriptions

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries). The supported version that is affected is Java SE: 10. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. 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 3.0 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).

Vulnerabilidad en el componente Java SE de Oracle Java SE (subcomponente: Libraries). La versión compatible afectada es Java SE: 10. Una vulnerabilidad difícilmente explotable permite que un atacante sin autenticar que tenga acceso a red por múltiples protocolos comprometa la seguridad de Java SE. Para que los ataques tengan éxito, se necesita la participación de otra persona diferente del atacante y, aunque la vulnerabilidad está presente en Java SE, los ataques podrían afectar seriamente a productos adicionales. Los ataques exitosos a esta vulnerabilidad pueden resultar en la toma de control de Java SE. Nota: Esta vulnerabilidad se aplica a implementaciones Java, normalmente en clientes que ejecutan aplicaciones Java Web Start en sandbox o applets Java en sandbox que cargan y ejecutan código que no es de confianza (por ejemplo, código proveniente de internet) y que confían en la sandbox de aislado Java para protegerse. Esta vulnerabilidad no se aplica a implementaciones Java, normalmente en servidores, que solo cargan y ejecutan código de confianza (por ejemplo, código instalado por un administrador). CVSS 3.0 Base Score 8.3 (impactos en la confidencialidad, integridad y disponibilidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Oracle Java. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the implementation of the tryFinally method in the MethodHandles class. Due to unsafe handling of reflection of privileged classes inside the MethodHandles class, it is possible for untrusted code to gain access to privileged methods and properties. An attacker can leverage this vulnerability to execute code under the context of the current process.
