Descriptions

In cloud foundry CAPI versions prior to 1.122, a denial-of-service attack in which a developer can push a service broker that (accidentally or maliciously) causes CC instances to timeout and fail is possible. An attacker can leverage this vulnerability to cause an inability for anyone to push or manage apps.

En Cloud Foundry CAPI versiones anteriores a 1.122, es posible un ataque de denegación de servicio en el que un desarrollador puede empujar un corredor de servicio que (accidentalmente o maliciosamente) causa que las instancias de CC sean agotadas y fallen si es posible. Un atacante puede aprovechar esta vulnerabilidad para causar la incapacidad de cualquiera de empujar o administrar aplicaciones
