Supported versions that are affected are Oracle Java SE: 8u471, 8u471-b50, 8u471-perf, 11.0.29, 17.0.17, 21.0.9, 25.0.1; Oracle GraalVM for JDK: 17.0.17 and 21.0.9; Oracle GraalVM Enterprise Edition: 21.3.16. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Java SE, Oracle GraalVM for JDK, 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).

Vulnerabilidad fácilmente explotable permite a un atacante no autenticado con acceso a la red a través de múltiples protocolos comprometer Oracle Java SE, Oracle GraalVM para JDK, Oracle GraalVM Enterprise Edition. Los ataques exitosos requieren interacción humana de una persona distinta al atacante y, si bien la vulnerabilidad está en Oracle Java SE, Oracle GraalVM para JDK, Oracle GraalVM Enterprise Edition, los ataques pueden impactar significativamente productos adicionales (cambio de alcance). Los ataques exitosos de esta vulnerabilidad pueden resultar en la creación, eliminación o modificación de acceso no autorizados a datos críticos o a todos los datos accesibles de Oracle Java SE, Oracle GraalVM para JDK, Oracle GraalVM Enterprise Edition. Nota: Esta vulnerabilidad se aplica a implementaciones de Java, típicamente en clientes que ejecutan aplicaciones Java Web Start en sandbox o applets de Java en sandbox, que cargan y ejecutan código no confiable (p. ej., código que proviene de internet) y dependen del sandbox de Java para la seguridad. Esta vulnerabilidad no se aplica a implementaciones de Java, típicamente en servidores, que cargan y ejecutan solo código confiable (p. ej., código instalado por un administrador).
