CVE-2016-9885: Pivotal Software Gemfire For Pivotal Cloud Foundry: Authentication bypass

CVE-2016-9885 is rated critical with a CVSS v3.0 base score of 9.8 and NVD lists Pivotal Software Gemfire For Pivotal Cloud Foundry as the affected product. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

An issue was discovered in Pivotal GemFire for PCF 1.6.x versions prior to 1.6.5 and 1.7.x versions prior to 1.7.1. 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 are 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.
