CVE-2016-4947: Cloudera HUE 3.9.0 and earlier allows remote attackers to enumerate user accounts via a request to desktop/...

Security readout for executives and security teams

This is an information disclosure issue in Cloudera Hue 3.9.0 and earlier. A remote requester may be able to learn valid user accounts through the user autocomplete function. It does not describe code execution or data theft, but account enumeration can support phishing, password attacks, and access targeting. Organizations running Cloudera Hue 3.9.0 or earlier are the stated exposure group. Risk is higher where Hue is reachable by untrusted networks or broad internal user populations. Treat as a moderate-priority exposure reduction item. It is not presented as direct system compromise, but it can improve an attacker’s ability to target valid accounts in a Hadoop environment. Mitigation focus: Inventory Hue deployments and confirm whether any are version 3.9.0 or earlier.; Check Cloudera guidance for fixed versions or supported configuration mitigations.; Restrict Hue access to trusted networks and authenticated users where operationally feasible..
