CVE-2016-4946
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple cross-site scripting (XSS) vulnerabilities in Cloudera HUE 3.9.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) First name or (2) Last name field in the HUE Users page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStored XSS vulnerability in Cloudera HUE 3.9.0 and earlier allows remote attackers to inject arbitrary JavaScript or HTML through the First name and Last name fields on the HUE Users page. When other users view the user profile, the malicious payload executes in their browser session.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed HUE versionLocate the HUE version information through the HUE web interface (typically in Help > About) or by checking the version of the hue package installed on the system using the package manager or hue version commandAffected if The installed version is Cloudera HUE 3.9.0 or any version earlier than 3.9.0
-
Verify access to the HUE user management interfaceLog into HUE and navigate to the Users administration page (typically accessible via Administration > Users or the Users icon in the navigation bar)Affected if The user management interface is accessible and users can be created or edited
-
Confirm user profile viewing is enabledCheck if HUE allows users to view other user profiles by accessing a user profile page (typically /hue/useradmin/users/<user_id>/) while logged in as a different userAffected if User profiles are viewable by other authenticated users in the system
-
Check if First name and Last name fields accept input without validationAttempt to create or edit a user through the HUE user management interface and observe if the First name and Last name fields accept special characters (<, >, ', ", script tags) without immediate rejection or sanitizationAffected if The First name and Last name fields accept and store HTML or JavaScript special characters without sanitization, and these values are reflected when other users view the profile
A user is affected if they are running Cloudera HUE version 3.9.0 or earlier and the HUE user management interface is accessible, allowing stored XSS payloads in First name/Last name fields to execute when other users view those profiles.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper input validation and output encoding on the First name and Last name fields in the HUE user management interface, or upgrade to a patched version of HUE that addresses this vulnerability.
