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.

pcs: Improper node name field validation when creating clusters leads to XSS

ClusterLabs pcs before version 0.9.157 is vulnerable to a cross-site scripting vulnerability due to improper validation of Node name field when creating new cluster or adding existing cluster.

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.

fence-agents: no verification of remote SSL certificates

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.

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.
