CVE-2021-32481
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 · uneditedCloudera Hue 4.6.0 allows XSS via the type parameter.
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 · moderate confidenceCloudera Hue 4.6.0 is vulnerable to reflected Cross-Site Scripting (XSS) via the 'type' parameter. User-supplied input in this parameter is insufficiently sanitized before being reflected in the HTTP response, allowing an attacker to inject malicious JavaScript code that executes in the context of a victim's browser.

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 if Cloudera Hue is installedCheck for running Hue processes (ps aux | grep hue) or look for Hue installation directories (common paths: /opt/cloudera/hue, /usr/local/hue, /home/hue). Also check if port 8888 (default Hue port) is listening.Affected if Cloudera Hue is not present in the environment - then not affected.
-
Determine the exact Hue versionAccess the Hue web interface and navigate to the About/Help page, or run 'hue --version' from the installation directory, or check the RPM/DEB package version with 'rpm -q hue' or 'dpkg -l hue'.Affected if Version equals 4.6.0 exactly - this is the vulnerable version.
-
Verify the Hue web interface is accessibleConfirm the Hue web application responds on its configured port (default 8888) by accessing http://hostname:8888 in a browser or via curl.Affected if The web interface is exposed and accessible - the XSS requires user interaction with the web application.
-
Identify if the vulnerable 'type' parameter existsInspect the HTTP requests/responses of Hue's file browser or similar features that may use a 'type' parameter. Common endpoints include filebrowser URLs. Manually test by adding type=test to a Hue URL and observing if it reflects in the response.Affected if The 'type' parameter is present in Hue's HTTP endpoints and reflects user input in the response without encoding.
You are affected only if Cloudera Hue version 4.6.0 is installed AND the web interface is accessible AND the application uses a 'type' parameter that reflects input without sanitization.

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 dataUpgrade Cloudera Hue to a version that addresses this vulnerability, or implement proper input validation and output encoding on the 'type' parameter to neutralize malicious script content.
