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…

An issue was discovered in ClusterLabs Hawk 2.x through 2.3.0-x. There is a Ruby shell code injection issue via the hawk_remember_me_id parameter in the login_from_cookie cookie. The user logout routine could be used by unauthenticated remote attackers to execute code as hauser.

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.

pcs before version 0.9.164 and 0.10 is vulnerable to a privilege escalation via authorized user malicious REST call. The REST interface of the pcsd service did not properly sanitize the file name from the /remote/put_file query. If the /etc/booth directory exists, an…

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"…

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.

An authorization flaw was found in Pacemaker before 1.1.16, where it did not properly guard its IPC interface. An attacker with an unprivileged account on a Pacemaker node could use this flaw to, for example, force the Local Resource Manager daemon to execute a script as root…

Cross-site request forgery (CSRF) vulnerability in pcsd web UI in pcs before 0.9.149.

A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption,…

Pacemaker before 1.1.15, when using pacemaker remote, might allow remote attackers to cause a denial of service (node disconnection) via an unauthenticated connection.

An ACL bypass flaw was found in pacemaker. An attacker having a local account on the cluster and in the haclient group could use IPC communication with various daemons directly to perform certain tasks that they would be prevented by ACLs from doing if they went through the…

libqb before 1.0.5 allows local users to overwrite arbitrary files via a symlink attack, because it uses predictable filenames (under /dev/shm and /tmp) without O_EXCL.

Session fixation vulnerability in pcsd in pcs before 0.9.157.

In fence-agents before 4.0.17 does not verify remote SSL certificates in the fence_cisco_ucs.py script which can potentially allow for man-in-the-middle attackers to spoof SSL servers via arbitrary SSL certificates.

stonith-ng in pacemaker and cluster-glue passed passwords as commandline parameters, making it possible for local attackers to gain access to passwords of the HA stack and potentially influence its operations. This is fixed in cluster-glue 1.0.6 and newer, and pacemaker 1.1.3…

Pacemaker before 1.1.6 configure script creates temporary files insecurely

A flaw was found in Booth, a cluster ticket manager. If a specially-crafted hash is passed to gcry_md_get_algo_dlen(), it may allow an invalid HMAC to be accepted by the Booth server.

pcs before versions 0.9.164 and 0.10 is vulnerable to a debug parameter removal bypass. REST interface of the pcsd service did not properly remove the pcs debug argument from the /run_pcs query, possibly disclosing sensitive information. A remote attacker with a valid token…

log_blackbox.c in libqb before 2.0.8 allows a buffer overflow via long log messages because the header size is not considered.

An issue was discovered in ClusterLabs Hawk (aka HA Web Konsole) through 2.3.0-15. It ships the binary hawk_invoke (built from tools/hawk_invoke.c), intended to be used as a setuid program. This allows the hacluster user to invoke certain commands as root (with an attempt to…
