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-2024-36843 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-2024-36843/ (Markdown: https://insights.sbomify.com/CVE-2024-36843/index.md)","id":"CVE-2024-36843","markdown":"https://insights.sbomify.com/CVE-2024-36843/index.md","name":"CVE-2024-36843","record":{"aliases":["DEBIAN-CVE-2024-36843","GHSA-mh44-x3cr-7p25","JLSEC-2026-1254","UBUNTU-CVE-2024-36843"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Modbus communication library","requires_auth":"none","summary":"A heap overflow in libmodbus allows attackers to execute arbitrary code or cause denial of service via crafted Modbus messages.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libmodbus","vendor":"libmodbus"}],"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-122","name":"Heap-based Buffer Overflow"}],"description":"libmodbus v3.1.6 was discovered to contain a heap overflow via the modbus_mapping_free() function.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2024-36843","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in n/a","id":"CVE-2024-36844"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2024-36842"},"products":["n/a"],"published":"2024-05-31","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-26793","kev_date_added":null,"published":"2024-05-01"},{"cvss_score":7.5,"headline":"Use after free in n/a","id":"CVE-2024-36844","kev_date_added":null,"published":"2024-05-31"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2024-34244","kev_date_added":null,"published":"2024-05-08"},{"cvss_score":4.8,"headline":"Stack-based Buffer Overflow in libmodbus library","id":"CVE-2024-10918","kev_date_added":null,"published":"2025-02-27"},{"cvss_score":4.3,"headline":"Denial of service in n/a","id":"CVE-2024-36845","kev_date_added":null,"published":"2024-05-31"}],"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":"2025-11-03","vendors":["n/a"]},"summary":"A heap overflow in libmodbus allows attackers to execute arbitrary code or cause denial of service via crafted Modbus messages.","url":"https://insights.sbomify.com/CVE-2024-36843/"}
