{"id":"CVE-2025-34271","state":"PUBLISHED","title":"Nagios Log Server < 2024R2.0.2 Cluster Manager Credential Requests Sent Over Plaintext","description":"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.","publishedAt":"2025-10-30T21:22:51.043Z","updatedAt":"2025-11-17T21:36:24.505Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Nagios Log Server"],"affected":[{"vendor":"Nagios","product":"Log Server","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"2024R2.0.2","versionType":"custom"}],"modules":["Cluster manager credential request/replication API"]}],"references":["https://www.nagios.com/products/security/#log-server-2024R2","https://www.nagios.com/changelog/#log-server","https://www.vulncheck.com/advisories/nagios-log-server-cluster-manager-credential-requests-sent-over-plaintext"],"weaknesses":["CWE-319"],"ingestedAt":"2026-10-29T20:09:03.054Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/34xxx/CVE-2025-34271.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-34271","state":"PUBLISHED","datePublished":"2025-10-30T21:22:51.043Z","dateUpdated":"2025-11-17T21:36:24.505Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2025-04-15T19:15:22.580Z"},"containers":{"cna":{"title":"Nagios Log Server < 2024R2.0.2 Cluster Manager Credential Requests Sent Over Plaintext","descriptions":[{"lang":"en","value":"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.
