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 · unedited
The Gluster file system through version 4.1.4 is vulnerable to abuse of the 'features/index' translator. A remote attacker with access to mount volumes could exploit this via the 'GF_XATTROP_ENTRY_IN_KEY' xattrop to create arbitrary, empty files on the target server.

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 confidence

GlusterFS through version 4.1.4 contains a vulnerability in the 'features/index' translator that allows remote attackers with mount access to create arbitrary empty files on the target server via the 'GF_XATTROP_ENTRY_IN_KEY' xattrop operation.

MitigationUpgrade GlusterFS to version 4.1.5 or later, or disable the 'features/index' translator if not required; also restrict mount access to trusted users.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check installed GlusterFS version
    Run command: glusterfs --version or rpm -q glusterfs-server
    Affected if The installed version is 4.1.4 or earlier (or unknown/unspecified) from the affected product list (Redhat Gluster Storage <= 4.1.4, Redhat Enterprise Linux 6.0/7.0, Debian 9.0)
  2. Identify volumes using the features/index translator
    Run: gluster volume list and for each volume inspect the translator graph with: gluster volume info <volumename> | grep -i index, or check volume configuration files in /var/lib/glusterd/vols/
    Affected if Any volume has the 'features/index' translator enabled or listed in its configuration
  3. Verify mount access controls
    Review /etc/glusterfs/glusterd.vol or volume-specific export settings to identify which clients/hosts have mount access, and check for any auth allow/reject settings
    Affected if Untrusted or unauthenticated users have mount access to affected volumes

A system is affected if it runs a vulnerable GlusterFS version (4.1.4 or earlier) AND has the features/index translator enabled on any volume that can be accessed by untrusted users.
