log_blackbox.c in libqb before 2.0.8

CVE-2023-39976 9.8 - Critical - August 08, 2023

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

Classic Buffer Overflow

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

CVE-2023-2319 9.8 - Critical - May 17, 2023

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.

A vulnerability was found in the PCS project

CVE-2022-2735 7.8 - High - September 06, 2022

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.

Incorrect Default Permissions

An issue was discovered in ClusterLabs Hawk (aka HA Web Konsole) through 2.3.0-15

CVE-2021-3020 8.8 - High - August 26, 2022

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 limit this to safe combinations). This user is able to execute an interactive "shell" that isn't limited to the commands specified in hawk_invoke, allowing escalation to root.

Improper Privilege Management

The authfile directive in the booth config file is ignored, preventing use of authentication in communications from node to node

CVE-2022-2553 6.5 - Medium - July 28, 2022

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.

authentification

A flaw was found in the Pacemaker configuration tool (pcs)

CVE-2022-1049 8.8 - High - March 25, 2022

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.

authentification

stonith-ng in pacemaker and cluster-glue passed passwords as commandline parameters

CVE-2010-2496 5.5 - Medium - October 18, 2021

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 and newer.

authentification

An ACL bypass flaw was found in pacemaker

CVE-2020-25654 7.2 - High - November 24, 2020

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 configuration.

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

CVE-2019-10153 5 - Medium - July 30, 2019

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 fence_rhevm 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.

libqb before 1.0.5 allows local users to overwrite arbitrary files via a symlink attack

CVE-2019-12779 7.1 - High - June 07, 2019

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.

insecure temporary file

A flaw was found in pacemaker up to and including version 2.0.1

CVE-2018-16878 5.5 - Medium - April 18, 2019

A flaw was found in pacemaker up to and including version 2.0.1. An insufficient verification inflicted preference of uncontrolled processes can lead to DoS

Resource Exhaustion

A flaw was found in the way pacemaker's client-server authentication was implemented in versions up to and including 2.0.0

CVE-2018-16877 7.8 - High - April 18, 2019

A flaw was found in the way pacemaker's client-server authentication was implemented in versions up to and including 2.0.0. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation.

A use-after-free flaw was found in pacemaker up to and including version 2.0.1 which could result in certain sensitive information to be leaked

CVE-2019-3885 7.5 - High - April 18, 2019

A use-after-free flaw was found in pacemaker up to and including version 2.0.1 which could result in certain sensitive information to be leaked via the system logs.

Dangling pointer

pcs before version 0.9.164 and 0.10 is vulnerable to a privilege escalation via authorized user malicious REST call

CVE-2018-1079 6.5 - Medium - April 12, 2018

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 authenticated attacker with write permissions could create or overwrite arbitrary files with arbitrary data outside of the /etc/booth directory, in the context of the pcsd process.

Directory traversal

pcs before versions 0.9.164 and 0.10 is vulnerable to a debug parameter removal bypass

CVE-2018-1086 7.5 - High - April 12, 2018

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 could use this flaw to elevate their privilege.
