GlusterFS Device Creation Vulnerability Exploited by Authenticated Attackers

CVE-2018-10923

Summary

An issue was identified in GlusterFS where the 'mknod' system call can be misused to create files that point to devices on a GlusterFS server node. This allows an authenticated attacker to potentially create arbitrary device files, leading to unauthorized access and the ability to read sensitive data from devices connected to the server. Such exploitation underscores the importance of applying security updates and vigilant monitoring of access controls within GlusterFS deployments.
