CVE-2016-5724
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 CDH before 5.9 has Potentially Sensitive Information in Diagnostic Support Bundles.
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 CDH versions prior to 5.9 included potentially sensitive information in diagnostic support bundles collected for troubleshooting. These bundles, intended for support purposes, inadvertently contained sensitive data that could be exposed to unauthorized parties.

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 installed CDH versionRun 'hadoop version' or check Cloudera Manager UI under Hosts > Version, or inspect /etc/cloudera-scm/cmfversion fileAffected if Version is below 5.9.0 (e.g., 5.8.x, 5.7.x, 5.6.x, etc.)
-
Locate diagnostic support bundlesSearch common log and support directories such as /var/log/cloudera-scm-support/ or directories referenced in Cloudera Manager under Support > Diagnostic BundlesAffected if Any .zip or .tar.gz bundles exist from versions prior to 5.9.0
-
Inspect bundle contents for sensitive dataExtract a sample bundle and search for files containing keywords such as 'password', 'keytab', 'secret', 'credential', or check XML/property files for plaintext credentialsAffected if Bundles contain kerberos keytabs, LDAP passwords, database credentials, or other sensitive configuration data
-
Identify who had access to bundlesReview filesystem permissions and access logs for the diagnostic bundle directories to determine if unauthorized users or systems accessed the filesAffected if Bundles were accessible to users or processes outside the authorized support team
You are affected if your CDH version is below 5.9.0 and diagnostic bundles collected prior to the upgrade exist and contain sensitive data accessible to unauthorized parties.

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 data5.9.0
Upgrade Cloudera CDH to version 5.9 or later to remediate the vulnerability. Review and securely dispose of any previously collected diagnostic bundles that may contain sensitive information.
