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-2025-37730 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- logstash (Bitnami): affected from 8.0.0; fixed in 8.18.1, 9.0.1\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-2025-37730/ (Markdown: https://insights.sbomify.com/CVE-2025-37730/index.md)","id":"CVE-2025-37730","markdown":"https://insights.sbomify.com/CVE-2025-37730/index.md","name":"CVE-2025-37730","record":{"aliases":["BIT-logstash-2025-37730","GHSA-qrf7-ph5v-mj2v"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Logstash TCP output","requires_auth":"none","summary":"Attackers can intercept Logstash TCP output traffic via man-in-the-middle attacks when full SSL verification is configured but hostname checks are skipped.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Improper certificate validation in Logstash's TCP output could lead to a man-in-the-middle (MitM) attack in “client” mode, as hostname verification in TCP output was not being performed when the ssl_verification_mode =\u003e full was set.","ecosystems":["Bitnami"],"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":"Logstash Improper Certificate Validation in TCP output","id":"CVE-2025-37730","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":1,"n_references":1,"next":{"headline":"Elasticsearch Improper Authentication","id":"CVE-2025-37731"},"packages":[{"ecosystem":"Bitnami","fixed":["8.18.1","9.0.1"],"introduced":["8.0.0","9.0.0"],"last_affected":[],"package":"logstash","purl":"pkg:bitnami/logstash","source":"BIT-logstash-2025-37730"}],"prev":{"headline":"Elastic Cloud Enterprise (ECE) Improper Neutralization of Special Elements Used in a Template Engine","id":"CVE-2025-37729"},"products":["Logstash"],"published":"2025-05-06","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-06","vendors":["Elastic"]},"summary":"Attackers can intercept Logstash TCP output traffic via man-in-the-middle attacks when full SSL verification is configured but hostname checks are skipped.","url":"https://insights.sbomify.com/CVE-2025-37730/"}
