Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-3935 in the wild and no public exploit code.\n\nAffected product: Eclipse Foundation 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-2024-3935/ (Markdown: https://insights.sbomify.com/CVE-2024-3935/index.md)","id":"CVE-2024-3935","markdown":"https://insights.sbomify.com/CVE-2024-3935/index.md","name":"CVE-2024-3935","record":{"aliases":["DEBIAN-CVE-2024-3935","GHSA-r5mw-c5jc-r788","ROOT-OS-ALPINE-318-CVE-2024-3935","ROOT-OS-ALPINE-319-CVE-2024-3935","ROOT-OS-ALPINE-320-CVE-2024-3935","UBUNTU-CVE-2024-3935","openSUSE-SU-2025:15074-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"MQTT broker","requires_auth":"low_privilege","summary":"A remote attacker can crash the MQTT broker by sending a crafted packet when bridge topic remapping is enabled.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"mosquitto","vendor":"eclipse"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"In Eclipse Mosquito, versions from 2.0.0 through 2.0.18, if a Mosquitto broker is configured to create an outgoing bridge connection, and that bridge connection has an incoming topic configured that makes use of topic remapping, then if the remote connection sends a crafted PUBLISH packet to the broker a double free will occur with a subsequent crash of the broker.","ecosystems":["openSUSE:Tumbleweed"],"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":"Eclipse Mosquito: Double free vulnerability","id":"CVE-2024-3935","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2024"},"n_packages":1,"n_references":3,"next":{"headline":"The Post Grid – Shortcode, Gutenberg Blocks and Elementor Addon for Post Grid \u003c= 7.6.1 - Missing Authorization","id":"CVE-2024-3936"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["2.0.21-2.1"],"introduced":["0"],"last_affected":[],"package":"mosquitto","purl":"pkg:rpm/opensuse/mosquitto\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2025:15074-1"}],"prev":{"headline":"Mercado Pago payments for WooCommerce 7.3.0 - 7.6.1 - Authenticated (Subscriber+) Arbitrary File Download","id":"CVE-2024-3934"},"products":["mosquitto"],"published":"2024-10-30","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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2025-11-03","vendors":["Eclipse Foundation"]},"summary":"A remote attacker can crash the MQTT broker by sending a crafted packet when bridge topic remapping is enabled.","url":"https://insights.sbomify.com/CVE-2024-3935/"}
