It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-1427 in the wild and no public exploit code.\n\nAffected product: mruby/mruby. 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-2022-1427/ (Markdown: https://insights.sbomify.com/CVE-2022-1427/index.md)","id":"CVE-2022-1427","markdown":"https://insights.sbomify.com/CVE-2022-1427/index.md","name":"CVE-2022-1427","record":{"aliases":["DEBIAN-CVE-2022-1427","GHSA-45gc-6g92-9g2j","UBUNTU-CVE-2022-1427"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"mruby library","requires_auth":"none","summary":"An out-of-bounds read in mruby allows attackers to potentially execute arbitrary code via crafted input.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"mruby","vendor":"mruby"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Out-of-bounds Read in mrb_obj_is_kind_of in in GitHub repository mruby/mruby prior to 3.2. # Impact: Possible arbitrary code execution if being exploited.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Out-of-bounds Read in mrb_obj_is_kind_of in in mruby/mruby","id":"CVE-2022-1427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in GitLab","id":"CVE-2022-1428"},"packages":[],"prev":{"headline":"Auth bypass in GitLab","id":"CVE-2022-1426"},"products":["mruby/mruby"],"published":"2022-04-22","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6838","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6839","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6840","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2018-10199","kev_date_added":null,"published":"2018-04-18"},{"cvss_score":9.3,"headline":"Use-After-Free in str_escape in mruby/mruby in mruby/mruby","id":"CVE-2022-1212","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.1,"headline":"NULL Pointer Dereference in mruby/mruby","id":"CVE-2021-4110","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":8.4,"headline":"Out-of-bounds Read in mrb_get_args in mruby/mruby","id":"CVE-2022-1276","kev_date_added":null,"published":"2022-04-10"}],"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":"2024-08-03","vendors":["mruby"]},"summary":"An out-of-bounds read in mruby allows attackers to potentially execute arbitrary code via crafted input.","url":"https://insights.sbomify.com/CVE-2022-1427/"}
