Description

According to the version of the glusterfs packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • A flaw was found in glusterfs which can lead to privilege escalation on gluster server nodes. An authenticated gluster client via TLS could use gluster cli with --remote-host command to add it self to trusted storage pool and perform privileged gluster operations like adding other machines to trusted storage pool, start, stop, and delete volumes.(CVE-2018-10841)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
