Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Improper access control
EUVDB-ID: #VU49118
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-25654
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in pacemaker. A local account on the cluster and in the haclient group can 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.
MitigationInstall updates from vendor's repository.
