CVE-2017-7677
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 environments that use external location for hive tables, Hive Authorizer in Apache Ranger before 0.7.1 should be checking RWX permission for create table.
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 confidenceThe Hive Authorizer in Apache Ranger versions before 0.7.1 fails to validate RWX (Read-Write-Execute) permissions when users create external Hive tables. External tables store data in user-specified locations outside the Hive warehouse, and the missing permission check could allow unauthorized table creation in arbitrary filesystem locations.

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 Apache Ranger versionCheck the Ranger admin UI under 'Settings > System Info' or inspect the ranger-admin pom.xml file in the installation directory, or run 'ranger-admin version' if CLI is availableAffected if version is 0.7.0 or earlier (any version <= 0.7.0)
-
Confirm Hive Authorizer is enabledIn Ranger admin UI, navigate to 'Access Manager > Resource Based Policies' and verify a Hive service policy exists and is enabled, or check the Hive plugin configuration file (ranger-hive-audit.xml or equivalent) for an active connection to RangerAffected if Hive Authorizer plugin is connected to a Ranger policy server running the vulnerable version
-
Verify external Hive table creation is permittedCheck Ranger Hive policies for any resource policy that allows CREATE TABLE operations on external table paths (often denoted by database/table wildcards or specific external storage locations), or query existing external tables via 'SHOW CREATE TABLE' in Hive to confirm external location parameters are in useAffected if CREATE TABLE permissions exist for external tables (tables with LOCATION pointing outside the Hive warehouse)
-
Inspect audit logs for unauthorized external table creationReview Ranger audit logs (typically in /var/log/ranger/audit/ or via the Ranger audit UI) for CREATE TABLE events where the table type is EXTERNAL and the location path is user-controlled outside the warehouse directoryAffected if Audit logs show external tables were created in locations not explicitly authorized or outside expected paths
If Apache Ranger version 0.7.0 or earlier is deployed with the Hive Authorizer enabled and external Hive table creation is permitted via Ranger policies, the environment is vulnerable to CVE-2017-7677.

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 Apache Ranger to version 0.7.1 or later, which implements proper RWX permission validation for external Hive table creation.
