It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-18018 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-2017-18018/ (Markdown: https://insights.sbomify.com/CVE-2017-18018/index.md)","id":"CVE-2017-18018","markdown":"https://insights.sbomify.com/CVE-2017-18018/index.md","name":"CVE-2017-18018","record":{"aliases":["ALPINE-CVE-2017-18018","DEBIAN-CVE-2017-18018","UBUNTU-CVE-2017-18018"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Coreutils","requires_auth":"low_privilege","summary":"Local attackers can exploit a race condition in chown/chgrp to modify ownership of arbitrary files, potentially leading to privilege escalation.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"coreutils","vendor":"gnu"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX \"-R -L\" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Race condition in n/a","id":"CVE-2017-18018","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2017-18019"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2017-18017"},"products":["n/a"],"published":"2018-01-04","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2015-4042","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2015-4041","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":5.5,"headline":"Coreutils: heap overflow in split --line-bytes with very long lines","id":"CVE-2024-0684","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":5.1,"headline":"Race condition in n/a","id":"CVE-2015-1865","kev_date_added":null,"published":"2017-09-20"},{"cvss_score":4.6,"headline":"Out‑of‑bounds Read in GNU coreutils","id":"CVE-2026-56391","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":4.6,"headline":"Privilege escalation in n/a","id":"CVE-2016-2781","kev_date_added":null,"published":"2017-02-07"}],"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-06-09","vendors":["n/a"]},"summary":"Local attackers can exploit a race condition in chown/chgrp to modify ownership of arbitrary files, potentially leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2017-18018/"}
