{"id":"UBUNTU-CVE-2022-2735","details":"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.","modified":"2026-01-30T01:55:47.253800Z","published":"2022-09-06T18:15:00Z","related":["USN-7614-1"],"upstream":["CVE-2022-2735"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-2735"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2022/09/01/4"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-2735"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7614-1"}],"affected":[{"package":{"name":"pcs","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/pcs@0.9.149-1ubuntu1.1+esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.149-1ubuntu1.1+esm1"}]}],"versions":["0.9.149-1","0.9.149-1ubuntu1","0.9.149-1ubuntu1.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"pcs","binary_version":"0.9.149-1ubuntu1.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-2735.json"}},{"package":{"name":"pcs","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/pcs@0.10.11-2ubuntu3+esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.11-2ubuntu3+esm1"}]}],"versions":["0.10.8-1ubuntu1","0.10.11-2ubuntu2","0.10.11-2ubuntu3"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"pcs","binary_version":"0.10.11-2ubuntu3+esm1"},{"binary_name":"pcs-snmp","binary_version":"0.10.11-2ubuntu3+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-2735.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
