An issue was discovered in ClusterLabs Hawk 2.x through 2.3.0-x. There is a Ruby shell code injection issue via the hawkremembermeid parameter in the loginfromcookie cookie. The user logout routine could be used by unauthenticated remote attackers to execute code as hauser.
It was discovered that an update for PCS package in RHBA-2023:2151 erratum released as part of Red Hat Enterprise Linux 9.2 failed to include the fix for the Webpack issue CVE-2023-28154 (for PCS package), which was previously addressed in Red Hat Enterprise Linux 9.1 via erratum RHSA-2023:1591. The CVE-2023-2319 was assigned to that Red Hat specific security regression in Red Hat Enterprise Linux 9.2.
Cross-site request forgery (CSRF) vulnerability in pcsd web UI in pcs before 0.9.149.
A flaw was found in the Pacemaker configuration tool (pcs). The pcs daemon was allowing expired accounts, and accounts with expired passwords to login when using PAM authentication. Therefore, unprivileged expired accounts that have been denied access could still login.
An issue was discovered in ClusterLabs Hawk (aka HA Web Konsole) through 2.3.0-15. It ships the binary hawkinvoke (built from tools/hawkinvoke.c), intended to be used as a setuid program. This allows the hacluster user to invoke certain commands as root (with an attempt to limit this to safe combinations). This user is able to execute an interactive "shell" that isn't limited to the commands specified in hawkinvoke, allowing escalation to root.
Session fixation vulnerability in pcsd in pcs before 0.9.157.
A security issue was discovered in pcs project. It is caused by incorrect permissions on a unix socket used for internal communication between pcs daemons. A privilege escalation could happen by obtaining authentication token for hacluster user. With the hacluster token, an attacker has complete control over the cluster managed by pcs. The bug was introduced in pcs version 0.10.5 by this bz [1]

An issue was discovered in ClusterLabs crmsh through 4.2.1. Local attackers able to call "crm history" (when "crm" is run) were able to execute commands via shell code injection to the crm history commandline, potentially allowing escalation of privileges.
The authfile directive in the booth config file is ignored, preventing use of authentication in communications from node to node. As a result, nodes that do not have the correct authentication key are not prevented from communicating with other nodes in the cluster.
A flaw was discovered in fence-agents, prior to version 4.3.4, where using non-ASCII characters in a guest VM's comment or other fields would cause fencerhevm to exit with an exception. In cluster environments, this could lead to preventing automated recovery or otherwise denying service to clusters of which that VM is a member.
