Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-11778 in the wild and no public exploit code.\n\nAffected product: The Eclipse Foundation 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-2019-11778/ (Markdown: https://insights.sbomify.com/CVE-2019-11778/index.md)","id":"CVE-2019-11778","markdown":"https://insights.sbomify.com/CVE-2019-11778/index.md","name":"CVE-2019-11778","record":{"aliases":["DEBIAN-CVE-2019-11778","GHSA-rr62-j9x2-468p"],"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 use-after-free vulnerability in Eclipse Mosquitto allows remote attackers to cause a denial of service via specific MQTT v5 client configurations.","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":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"If an MQTT v5 client connects to Eclipse Mosquitto versions 1.6.0 to 1.6.4 inclusive, sets a last will and testament, sets a will delay interval, sets a session expiry interval, and the will delay interval is set longer than the session expiry interval, then a use after free error occurs, which has the potential to cause a crash in some situations.","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":"Use after free in Eclipse Mosquitto","id":"CVE-2019-11778","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Eclipse Mosquitto","id":"CVE-2019-11779"},"packages":[],"prev":{"headline":"Improper Handling of Exceptional Conditions and Origin Validation Error in Eclipse Paho Java client library","id":"CVE-2019-11777"},"products":["Eclipse Mosquitto"],"published":"2019-09-18","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":"2024-08-04","vendors":["The Eclipse Foundation"]},"summary":"A use-after-free vulnerability in Eclipse Mosquitto allows remote attackers to cause a denial of service via specific MQTT v5 client configurations.","url":"https://insights.sbomify.com/CVE-2019-11778/"}
