CVE-2016-9271
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 Manager 5.7.x before 5.7.6, 5.8.x before 5.8.4, and 5.9.x before 5.9.1 allows XSS in the help search feature.
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 confidenceCross-site scripting (XSS) vulnerability in Cloudera Manager's help search feature allows attackers to inject malicious scripts through search queries, potentially executing in other users' browsers.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Determine Cloudera Manager versionCheck the installed Cloudera Manager version through the Admin Console (typically accessible at port 7180) by navigating to the 'Support' > 'About' page, or by running 'cloudera-manager-server --version' from the command line if you have server accessAffected if The installed version falls within any of these ranges: 5.0.0-5.0.7, 5.1.0-5.1.6, 5.2.0-5.2.7, 5.3.0-5.3.10, 5.4.0-5.4.3, 5.4.5-5.4.10, 5.5.0-5.5.6, 5.6.0-5.6.1, 5.7.0-5.7.5, 5.8.0-5.8.3, or is exactly 5.9.0
-
Verify help search feature is accessibleConfirm that the Cloudera Manager web interface is running and accessible. The help search feature is typically found in the help documentation section accessible from the main navigationAffected if The Cloudera Manager web interface is active and the help search functionality is available to users
-
Confirm help search accepts user inputAccess the help search field within Cloudera Manager (usually under 'Support' > 'Help' or within the documentation pages) and verify that it accepts text input for searchingAffected if The help search field accepts user-provided queries without sanitization
-
Check user access to help systemReview which user roles have access to the help search feature in Cloudera Manager by examining the user administration settings under 'Administration' > 'Users'Affected if Any authenticated or unauthenticated users can access the help search feature
You are affected if your Cloudera Manager version matches any of the listed vulnerable versions AND the help search feature is accessible to users in your environment.

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 Manager to version 5.7.6, 5.8.4, 5.9.1 or later to receive the patched version. As a temporary measure, disable or restrict access to the help search feature until patching is complete.
