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-2023-3592 in the wild and no public exploit code.\n\nAffected product: Eclipse Mosquitto. 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-2023-3592/ (Markdown: https://insights.sbomify.com/CVE-2023-3592/index.md)","id":"CVE-2023-3592","markdown":"https://insights.sbomify.com/CVE-2023-3592/index.md","name":"CVE-2023-3592","record":{"aliases":["ALPINE-CVE-2023-3592","DEBIAN-CVE-2023-3592","GHSA-p7q8-377q-px25","OESA-2024-1022","OESA-2024-1026","OESA-2024-1028","UBUNTU-CVE-2023-3592"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MQTT broker","requires_auth":"none","summary":"Attackers can cause a memory leak and potential denial of service in the Mosquitto MQTT broker by sending malformed v5 CONNECT packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"mosquitto","vendor":"eclipse"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types.","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":"Denial of service in Mosquitto","id":"CVE-2023-3592","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Server crash via a specially crafted markdown input","id":"CVE-2023-3593"},"packages":[],"prev":{"headline":"Lack of previous password reset tokens on new token creation","id":"CVE-2023-3591"},"products":["Mosquitto"],"published":"2023-10-02","related":[{"cvss_score":8.1,"headline":"Auth bypass in Eclipse Mosquitto","id":"CVE-2018-12550","kev_date_added":null,"published":"2019-03-27"},{"cvss_score":8.1,"headline":"Auth bypass in Eclipse Mosquitto","id":"CVE-2018-12551","kev_date_added":null,"published":"2019-03-27"},{"cvss_score":7.5,"headline":"Unconditionally adding an event to the epoll causes excessive CPU consumption","id":"CVE-2023-5632","kev_date_added":null,"published":"2023-10-18"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2023-28366","kev_date_added":null,"published":"2023-09-01"},{"cvss_score":7.5,"headline":"Denial of service in Eclipse Mosquitto","id":"CVE-2021-41039","kev_date_added":null,"published":"2021-12-01"},{"cvss_score":7.5,"headline":"Denial of service in Eclipse Mosquitto","id":"CVE-2021-34432","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":7.5,"headline":"Missing authorization in n/a","id":"CVE-2018-20145","kev_date_added":null,"published":"2018-12-13"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Eclipse"]},"summary":"Attackers can cause a memory leak and potential denial of service in the Mosquitto MQTT broker by sending malformed v5 CONNECT packets.","url":"https://insights.sbomify.com/CVE-2023-3592/"}
