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-2018-3718 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- serve (npm): affected all versions; fixed in 6.5.2\n- serve (npm): affected all versions; fixed in 6.5.2\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-2018-3718/ (Markdown: https://insights.sbomify.com/CVE-2018-3718/index.md)","id":"CVE-2018-3718","markdown":"https://insights.sbomify.com/CVE-2018-3718/index.md","name":"CVE-2018-3718","record":{"aliases":["GHSA-5rc4-8qqh-vq7f"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js static server","requires_auth":"none","summary":"Attackers can bypass file access restrictions to read ignored files by using URL-encoded filenames in the serve Node.js module.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"serve","vendor":"zeit"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-177","name":"Improper Handling of URL Encoding (Hex Encoding)"}],"description":"serve node module suffers from Improper Handling of URL Encoding by permitting access to ignored files if a filename is URL encoded.","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":"vercel/serve allows access to restricted files if filename is URL encoded.","id":"CVE-2018-3718","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"Prototype Pollution in mixin-deep","id":"CVE-2018-3719"},"packages":[{"ecosystem":"npm","fixed":["6.5.2"],"introduced":["0"],"last_affected":[],"package":"serve","purl":null,"source":"GHSA-5rc4-8qqh-vq7f"},{"ecosystem":"npm","fixed":["6.5.2"],"introduced":["0"],"last_affected":[],"package":"serve","purl":"pkg:npm/serve","source":"GHSA-5rc4-8qqh-vq7f"}],"prev":{"headline":"Cross-Site Scripting in connect","id":"CVE-2018-3717"},"products":["serve node module"],"published":"2018-06-07","related":[{"cvss_score":7.5,"headline":"Path Traversal in serve","id":"CVE-2019-5415","kev_date_added":null,"published":"2019-03-17"},{"cvss_score":7.5,"headline":"Directory Traversal in serve","id":"CVE-2019-5417","kev_date_added":null,"published":"2019-03-17"},{"cvss_score":6.5,"headline":"Directory Traversal in serve","id":"CVE-2018-3712","kev_date_added":null,"published":"2018-06-07"},{"cvss_score":5.3,"headline":"Information Exposure on Case Insensitive File Systems in serve","id":"CVE-2018-3809","kev_date_added":null,"published":"2018-06-01"}],"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":"2024-09-16","vendors":["HackerOne"]},"summary":"Attackers can bypass file access restrictions to read ignored files by using URL-encoded filenames in the serve Node.js module.","url":"https://insights.sbomify.com/CVE-2018-3718/"}
