{"id":"CVE-2025-34271","details":"Nagios Log Server versions prior to 2024R2.0.2 contain a vulnerability in the cluster manager component when requesting sensitive credentials from peer nodes over an unencrypted channel even when SSL/TLS is enabled in the product configuration. As a result, an attacker positioned on the network path can intercept credentials in transit. Captured credentials could allow the attacker to authenticate as a cluster node or service account, enabling further unauthorized access, lateral movement, or system compromise.","modified":"2026-03-14T15:02:08.060124Z","published":"2025-10-30T22:15:47.673Z","references":[{"type":"ADVISORY","url":"https://www.nagios.com/changelog/#log-server"},{"type":"ADVISORY","url":"https://www.nagios.com/products/security/#log-server-2024R2"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/nagios-log-server-cluster-manager-credential-requests-sent-over-plaintext"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"2024"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.0\\.1"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.0\\.2"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.1"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.2"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.3"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.3\\.1"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.3\\.2"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.3\\.3"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.3\\.4"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r1\\.3\\.5"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r2"}]},{"events":[{"introduced":"0"},{"last_affected":"2024-r2\\.0\\.1"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-34271.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
