It was found that glusterfs server does not properly sanitize file paths in the trusted.io-stats-dump extended attribute which is used by the debug/io-stats translator. Attacker can use this flaw to create files and execute arbitrary code. To exploit this attacker would require sufficient access to modify the extended attributes of files on a gluster volume.
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
