How to fix?

Upgrade RHEL:9 pcs to version 0:0.11.1-10.el9_0.2 or higher.
This issue was patched in RHSA-2022:6313.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pcs package and not the pcs package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A vulnerability was found in the PCS project. This issue occurs due to incorrect permissions on a Unix socket used for internal communication between PCS daemons. A privilege escalation could happen by obtaining an authentication token for a hacluster user. With the "hacluster" token, this flaw allows an attacker to have complete control over the cluster managed by PCS.
