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.
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.
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.
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.
