An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-29995 exists.\n\nAffected product: n/a. 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-2023-29995/ (Markdown: https://insights.sbomify.com/CVE-2023-29995/index.md)","id":"CVE-2023-29995","markdown":"https://insights.sbomify.com/CVE-2023-29995/index.md","name":"CVE-2023-29995","record":{"aliases":["GHSA-6h45-p2j6-r9ph"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MQTT broker","requires_auth":"none","summary":"A heap overflow in NanoMQ's MQTT parser allows attackers to execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nanomq","vendor":"emqx"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-787","name":"Out-of-bounds Write"}],"description":"In NanoMQ v0.15.0-0, a Heap overflow occurs in copyn_utf8_str function of mqtt_parser.c","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2023-29995","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in n/a","id":"CVE-2023-29996"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-29994"},"products":["n/a"],"published":"2023-05-04","related":[{"cvss_score":8.8,"headline":"Missing authorization in n/a","id":"CVE-2024-42655","kev_date_added":null,"published":"2025-07-29"},{"cvss_score":8.5,"headline":"NanoMQ has Buffer Overflow","id":"CVE-2025-59947","kev_date_added":null,"published":"2025-12-15"},{"cvss_score":8,"headline":"Memory corruption in n/a","id":"CVE-2023-34488","kev_date_added":null,"published":"2023-06-12"},{"cvss_score":7.7,"headline":"NanoMQ has Heap Buffer Overflow in URI Parameter Parsing","id":"CVE-2026-32135","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2026-36590","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":7.5,"headline":"MQTT v5 Variable Byte Integer parsing out-of-bounds: get_var_integer()","id":"CVE-2026-21888","kev_date_added":null,"published":"2026-03-11"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-48077","kev_date_added":null,"published":"2026-01-15"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-29","vendors":["n/a"]},"summary":"A heap overflow in NanoMQ's MQTT parser allows attackers to execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2023-29995/"}
