Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2022-9753 advisory.

 - 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. (CVE-2022-2735)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected pcs and / or pcs-snmp packages.
