CVE-2016-8744

Estado: ModificadaAlta (8.8)—

Apache Brooklyn uses the SnakeYAML library for parsing YAML inputs. SnakeYAML allows the use of YAML tags to indicate that SnakeYAML should unmarshal data to a Java type. In the default configuration in Brooklyn before 0.10.0, SnakeYAML will allow unmarshalling to any Java type available on the classpath. This could provide an authenticated user with a means to cause the JVM running Brooklyn to load and run Java code without detection by Brooklyn. Such code would have the privileges of the Java process running Brooklyn, including the ability to open files and network connections, and execute system commands. There is known to be a proof-of-concept exploit using this vulnerability.

SnakeYAML permite el uso de etiquetas YAML para indicar que esta librería debería deserializar datos para tipo Java. En la configuración por defecto en Brooklyn en versiones anteriores a la 0.10.0, SnakeYAML permite deserializar cualquier tipo de Java disponible en el classpath. Esto podría proporcionar a un usuario autenticado los medios para hacer que la máquina virtual Java que está ejecutando Brooklyn cargue y ejecute código Java sin que Brooklyn lo detecte. Ese código tendría los privilegios del proceso Java que ejecuta Brooklyn, incluida la capacidad de abrir archivos y conexiones de red y ejecutar comandos del sistema. Se sabe que existe un exploit a modo de prueba de concepto que utiliza esta vulnerabilidad."
