CVE-2018-1317
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 · uneditedIn Apache Zeppelin prior to 0.8.0 the cron scheduler was enabled by default and could allow users to run paragraphs as other users without authentication.
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 confidenceIn Apache Zeppelin prior to version 0.8.0, the cron scheduler was enabled by default without authentication controls. This allowed any authenticated Zeppelin user to exploit the scheduler to execute paragraphs (code cells) as other users, achieving privilege escalation.

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 installed Zeppelin versionCheck the Zeppelin version by inspecting the About page in the Zeppelin UI, or by checking the Zeppelin web application's response headers, or by reviewing deployment artifacts/packaging that specify the installed version.Affected if The installed version is Apache Zeppelin prior to 0.8.0 (for example, 0.7.x, 0.6.x, or earlier releases).
-
Determine if cron scheduler is enabledReview the Zeppelin configuration file (zeppelin-site.xml or equivalent) for the setting that controls cron scheduler enablement. Look for a property related to 'cron' or 'scheduler' and check if it is set to true or enabled.Affected if The cron scheduler feature is explicitly enabled or was left at default settings in versions prior to 0.8.0.
-
Inspect cron job submissionsAccess the Zeppelin interpreter or scheduler settings UI and look for any scheduled cron jobs (paragraphs with cron triggers). Examine who created them and which users' identities they execute under.Affected if There are existing cron jobs present, particularly if they were created by untrusted users or if they run under elevated user contexts.
You are affected if you are running Apache Zeppelin version 0.8.0 or earlier AND the cron scheduler feature remains enabled, allowing any authenticated user to schedule paragraph execution under other users' identities.

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 data0.8.0
Upgrade Apache Zeppelin to version 0.8.0 or later, which disables the cron scheduler by default. If immediate upgrade is not feasible, disable the cron scheduler feature via Zeppelin configuration.
