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-2019-5432 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mqtt-packet (npm): affected all versions; fixed in 3.5.1\n- mqtt-packet (npm): affected all versions; fixed in 3.5.1\n- mqtt-packet (npm): affected from 4.0.0; fixed in 4.1.3\n- mqtt-packet (npm): affected from 4.0.0; fixed in 4.1.3\n- mqtt-packet (npm): affected from 5.0.0; fixed in 5.6.1\n- mqtt-packet (npm): affected from 5.0.0; fixed in 5.6.1\n- mqtt-packet (npm): affected from 6.0.0; fixed in 6.1.2\n- mqtt-packet (npm): affected from 6.0.0; fixed in 6.1.2\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-2019-5432/ (Markdown: https://insights.sbomify.com/CVE-2019-5432/index.md)","id":"CVE-2019-5432","markdown":"https://insights.sbomify.com/CVE-2019-5432/index.md","name":"CVE-2019-5432","record":{"aliases":["DEBIAN-CVE-2019-5432","GHSA-wv67-9jq7-8r69","UBUNTU-CVE-2019-5432"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MQTT packet parser","requires_auth":"none","summary":"A malformed MQTT Subscribe packet crashes MQTT brokers using the mqtt-packet library, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"mqtt-packet","vendor":"mqtt-packet_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-126","name":"Buffer Over-read"}],"description":"A specifically malformed MQTT Subscribe packet crashes MQTT Brokers using the mqtt-packet module versions \u003c 3.5.1, 4.0.0 - 4.1.3, 5.0.0 - 5.6.1, 6.0.0 - 6.1.2 for decoding.","ecosystems":["npm"],"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":"Improper Input Validation and Buffer Over-read in mqtt-packet","id":"CVE-2019-5432","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":8,"n_references":1,"next":{"headline":"Open redirect in Revive Adserver","id":"CVE-2019-5433"},"packages":[{"ecosystem":"npm","fixed":["3.5.1"],"introduced":["0"],"last_affected":[],"package":"mqtt-packet","purl":null,"source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["3.5.1"],"introduced":["0"],"last_affected":[],"package":"mqtt-packet","purl":"pkg:npm/mqtt-packet","source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["4.1.3"],"introduced":["4.0.0"],"last_affected":[],"package":"mqtt-packet","purl":null,"source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["4.1.3"],"introduced":["4.0.0"],"last_affected":[],"package":"mqtt-packet","purl":"pkg:npm/mqtt-packet","source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["5.6.1"],"introduced":["5.0.0"],"last_affected":[],"package":"mqtt-packet","purl":null,"source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["5.6.1"],"introduced":["5.0.0"],"last_affected":[],"package":"mqtt-packet","purl":"pkg:npm/mqtt-packet","source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["6.1.2"],"introduced":["6.0.0"],"last_affected":[],"package":"mqtt-packet","purl":null,"source":"GHSA-wv67-9jq7-8r69"},{"ecosystem":"npm","fixed":["6.1.2"],"introduced":["6.0.0"],"last_affected":[],"package":"mqtt-packet","purl":"pkg:npm/mqtt-packet","source":"GHSA-wv67-9jq7-8r69"}],"prev":{"headline":"Auth bypass in Twitter Kit for iOS","id":"CVE-2019-5431"},"products":["mqtt-packet"],"published":"2019-05-06","related":[{"cvss_score":7.5,"headline":"Denial of Service in mqtt-packet","id":"CVE-2016-10523","kev_date_added":null,"published":"2018-05-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":["n/a"]},"summary":"A malformed MQTT Subscribe packet crashes MQTT brokers using the mqtt-packet library, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2019-5432/"}
