      "value": "The Management Console in GitHub Enterprise 2.8.x before 2.8.7 has a deserialization issue that allows unauthenticated remote attackers to execute arbitrary code. This occurs because the enterprise session secret is always the same, and can be found in the product's source code. By sending a crafted cookie signed with this secret, one can call Marshal.load with arbitrary data, which is a problem because the Marshal data format allows Ruby objects."

      "value": "La consola de gesti\u00f3n en GitHub Enterprise, en las versiones 2.8.x anteriores a la 2.8.7, tiene un fallo de deserializaci\u00f3n que permite a los atacantes remotos sin autenticar ejecutar c\u00f3digo arbitrario. Esto ocurre debido a que el secreto de sesi\u00f3n \"enterprise\" es siempre el mismo y puede encontrarse en el c\u00f3digo fuente del producto. Al enviar una cookie manipulada firmada con este secreto, se puede llamar a Marshal.load con datos arbitrarios. Esto es problem\u00e1tico, ya que el formato de los datos Marshal permite los objetos Ruby."
