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-2019-11838 in the wild and no public exploit code.\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-2019-11838/ (Markdown: https://insights.sbomify.com/CVE-2019-11838/index.md)","id":"CVE-2019-11838","markdown":"https://insights.sbomify.com/CVE-2019-11838/index.md","name":"CVE-2019-11838","record":{"aliases":["GHSA-5cqj-x29q-49hf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NGINX JavaScript library","requires_auth":"none","summary":"Heap-based buffer overflow in njs Array.prototype.splice allows attackers to execute arbitrary code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"njs","vendor":"f5"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"njs through 0.3.1, used in NGINX, has a heap-based buffer overflow in Array.prototype.splice after a resize, related to njs_array_prototype_splice in njs/njs_array.c, because of njs_array_expand size mishandling.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2019-11838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2019-11839"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2019-11837"},"products":["n/a"],"published":"2019-05-09","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":"Use after free in n/a","id":"CVE-2022-43286","kev_date_added":null,"published":"2022-10-28"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Heap-based buffer overflow in njs Array.prototype.splice allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2019-11838/"}
