Pacemaker: pacemaker: denial of service via integer overflow in remote message decompression

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, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing.

pacemaker: pacemaker remote nodes vulnerable to hijacking, resulting in a DoS attack

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.

pacemaker: acl read-only access allow role assignment

Pacemaker before 1.1.13 does not properly evaluate added nodes, which allows remote read-only users to gain privileges via an acl command.

pacemaker: remote DoS when CIB management is enabled caused by use of blocking sockets

Pacemaker 1.1.10, when remote Cluster Information Base (CIB) configuration or resource management is enabled, does not limit the duration of connections to the blocking sockets, which allows remote attackers to cause a denial of service (connection blocking).

pacemaker: ACL restrictions bypass

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.

pacemaker: Information disclosure through use-after-free

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.

pcs: Debug parameter removal bypass, allowing information disclosure

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.

pcs: Privilege escalation via authorized user malicious REST call

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.

pacemaker: Insufficient verification inflicted preference of uncontrolled processes can lead to DoS

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

pacemaker: Insufficient local IPC client-server authentication on the client's side can lead to local privesc

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.

pacemaker: Privilege escalation due to improper guarding of IPC communication

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 and thereby gain root access on the machine.

Pacemaker before 1.1.6 configure script creates temporary files insecurely

cluster-glue: passes the stonith parameters via the commandline which could result in password leaks

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.
