An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-39665 in the wild and no public exploit code.\n\nAffected product: Nagvis. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-39665/ (Markdown: https://insights.sbomify.com/CVE-2025-39665/index.md)","id":"CVE-2025-39665","markdown":"https://insights.sbomify.com/CVE-2025-39665/index.md","name":"CVE-2025-39665","record":{"aliases":["DEBIAN-CVE-2025-39665","GHSA-2x34-p5xr-4cq8","UBUNTU-CVE-2025-39665"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Nagvis monitoring tool","requires_auth":"none","summary":"An unauthenticated attacker can enumerate Checkmk usernames via user enumeration in Nagvis' Checkmk MultisiteAuth.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Checkmk","cpe":[{"product":"nagvis","vendor":"nagvis"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"User enumeration in Nagvis' Checkmk MultisiteAuth before version 1.9.48 allows an unauthenticated attacker to enumerate Checkmk usernames.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Livestatus Injection in dynmaps","id":"CVE-2025-39665","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"omd: Local privilege escalation when executing omd commands as root","id":"CVE-2025-39666"},"packages":[],"prev":{"headline":"Path-Traversal in report scheduler","id":"CVE-2025-39664"},"products":["Nagvis"],"published":"2025-12-03","related":[{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2022-46945","kev_date_added":null,"published":"2023-05-26"},{"cvss_score":8.8,"headline":"Fix various XSS issues and potential RCE","id":"CVE-2024-47093","kev_date_added":null,"published":"2024-12-19"},{"cvss_score":6.5,"headline":"Path traversal in NagVis","id":"CVE-2021-33178","kev_date_added":null,"published":"2021-10-14"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2023-46287","kev_date_added":null,"published":"2023-10-20"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2017-6393","kev_date_added":null,"published":"2017-03-02"},{"cvss_score":5.6,"headline":"NagVis CoreLogonMultisite.php checkAuthCookie type conversion","id":"CVE-2022-3979","kev_date_added":null,"published":"2022-11-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-03","vendors":["Nagvis"]},"summary":"An unauthenticated attacker can enumerate Checkmk usernames via user enumeration in Nagvis' Checkmk MultisiteAuth.","url":"https://insights.sbomify.com/CVE-2025-39665/"}
