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-2023-42276 exists.\n\nAffected packages and fixed versions:\n- cn.hutool:hutool-core (Maven): affected all versions up to 5.8.21; no fix listed\n- cn.hutool:hutool-core (Maven): affected all versions up to 5.8.21; no fix listed\n- cn.hutool:hutool-json (Maven): affected all versions up to 5.8.21; no fix listed\n- cn.hutool:hutool-json (Maven): affected all versions up to 5.8.21; no fix listed\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-2023-42276/ (Markdown: https://insights.sbomify.com/CVE-2023-42276/index.md)","id":"CVE-2023-42276","markdown":"https://insights.sbomify.com/CVE-2023-42276/index.md","name":"CVE-2023-42276","record":{"aliases":["GHSA-rxgf-r843-g53h"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java utility library","requires_auth":"none","summary":"A buffer overflow in the Hutool Java library's jsonArray component allows attackers to potentially execute 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":"hutool","vendor":"hutool"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"hutool v5.8.21 was discovered to contain a buffer overflow via the component jsonArray.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"hutool Buffer Overflow vulnerability","id":"CVE-2023-42276","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":4,"n_references":1,"next":{"headline":"hutool Buffer Overflow vulnerability","id":"CVE-2023-42277"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.8.21"],"package":"cn.hutool:hutool-core","purl":null,"source":"GHSA-rxgf-r843-g53h"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.8.21"],"package":"cn.hutool:hutool-core","purl":"pkg:maven/cn.hutool/hutool-core","source":"GHSA-rxgf-r843-g53h"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.8.21"],"package":"cn.hutool:hutool-json","purl":null,"source":"GHSA-rxgf-r843-g53h"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.8.21"],"package":"cn.hutool:hutool-json","purl":"pkg:maven/cn.hutool/hutool-json","source":"GHSA-rxgf-r843-g53h"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2023-42270"},"products":["n/a"],"published":"2023-09-08","related":[{"cvss_score":9.8,"headline":"hutool Buffer Overflow vulnerability","id":"CVE-2023-42277","kev_date_added":null,"published":"2023-09-08"},{"cvss_score":9.8,"headline":"Dromara Hutool Deserialization of Untrusted Data vulnerability","id":"CVE-2023-24162","kev_date_added":null,"published":"2023-01-31"},{"cvss_score":9.8,"headline":"Dromara hutool vulnerable to SQL Injection","id":"CVE-2023-24163","kev_date_added":null,"published":"2023-01-31"},{"cvss_score":9.8,"headline":"Improper Certificate Validation in Hutool","id":"CVE-2022-22885","kev_date_added":null,"published":"2022-02-16"},{"cvss_score":7.5,"headline":"hutool-core discovered to contain an infinite loop in the StrSplitter.splitByRegex function","id":"CVE-2023-51075","kev_date_added":null,"published":"2023-12-27"},{"cvss_score":7.5,"headline":"hutool-core was discovered to contain a stack overflow via NumberUtil.toBigDecimal method","id":"CVE-2023-51080","kev_date_added":null,"published":"2023-12-27"}],"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-26","vendors":["n/a"]},"summary":"A buffer overflow in the Hutool Java library's jsonArray component allows attackers to potentially execute code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2023-42276/"}
