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-2023-6016 in the wild and no public exploit code.\n\nAffected product: h2oai/h2o-3. 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-2023-6016/ (Markdown: https://insights.sbomify.com/CVE-2023-6016/index.md)","id":"CVE-2023-6016","markdown":"https://insights.sbomify.com/CVE-2023-6016/index.md","name":"CVE-2023-6016","record":{"aliases":["GHSA-p3v8-5qc4-7p8r"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"H2O AI platform","requires_auth":"none","summary":"Attackers can achieve remote code execution on H2O servers by exploiting the POJO model import feature.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"h2o","vendor":"h2o"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"An attacker is able to gain remote code execution on a server hosting the H2O dashboard through it's POJO model import feature.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"H2O Remote Code Execution via POJO Model Import","id":"CVE-2023-6016","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"H2O S3 Bucket Takeover","id":"CVE-2023-6017"},"packages":[],"prev":{"headline":"MLflow Arbitrary File Upload","id":"CVE-2023-6015"},"products":["h2oai/h2o-3"],"published":"2023-11-16","related":[{"cvss_score":9.8,"headline":"Deserialization Vulnerability in h2oai/h2o-3","id":"CVE-2025-6544","kev_date_added":null,"published":"2025-09-21"},{"cvss_score":9.8,"headline":"Jdbc Deserialization in h2oai/h2o-3","id":"CVE-2024-10553","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":9.3,"headline":"External Control of File Name or Path in h2oai/h2o-3","id":"CVE-2023-6569","kev_date_added":null,"published":"2023-12-14"},{"cvss_score":9.3,"headline":"H2O Local File Include","id":"CVE-2023-6013","kev_date_added":null,"published":"2023-11-16"},{"cvss_score":9.3,"headline":"Local File Inclusion in h2oai/h2o-3","id":"CVE-2023-6038","kev_date_added":null,"published":"2023-11-16"},{"cvss_score":9.1,"headline":"H2O.ai H2O vulnerable to deserialization attacks via a JDBC Connection URL","id":"CVE-2024-45758","kev_date_added":null,"published":"2024-09-06"}],"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":"2024-08-02","vendors":["h2oai"]},"summary":"Attackers can achieve remote code execution on H2O servers by exploiting the POJO model import feature.","url":"https://insights.sbomify.com/CVE-2023-6016/"}
