CVE-2018-14654: Path Traversal
First published: Fri Sep 21 2018(Updated: )
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.
