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-2017-18869 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- chownr (npm): affected all versions; fixed in 1.1.0\n- chownr (npm): affected all versions; fixed in 1.1.0\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-2017-18869/ (Markdown: https://insights.sbomify.com/CVE-2017-18869/index.md)","id":"CVE-2017-18869","markdown":"https://insights.sbomify.com/CVE-2017-18869/index.md","name":"CVE-2017-18869","record":{"aliases":["CLSA-2026-1772669620","CLSA-2026-1773706634","DEBIAN-CVE-2017-18869","GHSA-c6rq-rjc2-86v2","MGASA-2021-0169","UBUNTU-CVE-2017-18869"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Node.js chownr package","requires_auth":"low_privilege","summary":"A local attacker can exploit a race condition in the chownr library to modify files in unintended directories via symlink attacks.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"chownr","vendor":"chownr_project"}],"cvss":{"score":2.5,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"A TOCTOU issue in the chownr package before 1.1.0 for Node.js 10.10 could allow a local attacker to trick it into descending into unintended directories via symlink attacks.","ecosystems":["npm"],"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":"Time-of-check Time-of-use (TOCTOU) Race Condition in chownr","id":"CVE-2017-18869","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"race_condition","year":"2017"},"n_packages":2,"n_references":4,"next":{"headline":"Missing authorization in n/a","id":"CVE-2017-18870"},"packages":[{"ecosystem":"npm","fixed":["1.1.0"],"introduced":["0"],"last_affected":[],"package":"chownr","purl":null,"source":"GHSA-c6rq-rjc2-86v2"},{"ecosystem":"npm","fixed":["1.1.0"],"introduced":["0"],"last_affected":[],"package":"chownr","purl":"pkg:npm/chownr","source":"GHSA-c6rq-rjc2-86v2"}],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2017-18868"},"products":["n/a"],"published":"2020-06-15","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"A local attacker can exploit a race condition in the chownr library to modify files in unintended directories via symlink attacks.","url":"https://insights.sbomify.com/CVE-2017-18869/"}
