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-2022-43286 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-2022-43286/ (Markdown: https://insights.sbomify.com/CVE-2022-43286/index.md)","id":"CVE-2022-43286","markdown":"https://insights.sbomify.com/CVE-2022-43286/index.md","name":"CVE-2022-43286","record":{"aliases":["GHSA-qw9g-h8v6-7xfq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nginx NJS library","requires_auth":"none","summary":"A heap-use-after-free in Nginx NJS allows attackers to execute arbitrary code or cause denial of service via crafted JSON input.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"njs","vendor":"f5"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Nginx NJS v0.7.2 was discovered to contain a heap-use-after-free bug caused by illegal memory copy in the function njs_json_parse_iterator_call at njs_json.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":"Use after free in n/a","id":"CVE-2022-43286","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in n/a","id":"CVE-2022-43288"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2022-43285"},"products":["n/a"],"published":"2022-10-28","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19692","kev_date_added":null,"published":"2023-04-04"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19695","kev_date_added":null,"published":"2023-04-04"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2022-29379","kev_date_added":null,"published":"2022-05-25"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-27007","kev_date_added":null,"published":"2022-04-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-46463","kev_date_added":null,"published":"2022-02-14"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-25139","kev_date_added":null,"published":"2022-02-14"}],"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":"total"},"state":"PUBLISHED","updated":"2025-05-07","vendors":["n/a"]},"summary":"A heap-use-after-free in Nginx NJS allows attackers to execute arbitrary code or cause denial of service via crafted JSON input.","url":"https://insights.sbomify.com/CVE-2022-43286/"}
