CVE-2016-9885 gfsh exposed over go router for GemFire for PCF






The gfsh (Geode Shell) endpoint, used by operators and application developers to connect to their cluster, is unauthenticated and publicly accessible. Because HTTPS communications are terminated at the gorouter, communications from the gorouter to GemFire clusters is unencrypted. An attacker could run any command available on gfsh and could cause denial of service, lost confidentiality of data, escalate privileges, or eavesdrop on other communications between the gorouter and the cluster.
