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-2018-3770 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- markdown-pdf (npm): affected all versions; fixed in 9.0.0\n- markdown-pdf (npm): affected all versions; fixed in 9.0.0\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-2018-3770/ (Markdown: https://insights.sbomify.com/CVE-2018-3770/index.md)","id":"CVE-2018-3770","markdown":"https://insights.sbomify.com/CVE-2018-3770/index.md","name":"CVE-2018-3770","record":{"aliases":["GHSA-p7c9-jqhq-vr3v"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Node.js markdown library","requires_auth":"low_privilege","summary":"An attacker can exploit a path traversal vulnerability in the markdown-pdf library to read arbitrary local files from the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"markdown-pdf","vendor":"markdown-pdf_project"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A path traversal exists in markdown-pdf version \u003c9.0.0 that allows a user to insert a malicious html code that can result in reading the local files.","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":"Remote Code Execution in markdown-pdf","id":"CVE-2018-3770","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":"statics-server Cross-site Scripting vulnerability","id":"CVE-2018-3771"},"packages":[{"ecosystem":"npm","fixed":["9.0.0"],"introduced":["0"],"last_affected":[],"package":"markdown-pdf","purl":null,"source":"GHSA-p7c9-jqhq-vr3v"},{"ecosystem":"npm","fixed":["9.0.0"],"introduced":["0"],"last_affected":[],"package":"markdown-pdf","purl":"pkg:npm/markdown-pdf","source":"GHSA-p7c9-jqhq-vr3v"}],"prev":{"headline":"grape subject to Cross-site Scripting","id":"CVE-2018-3769"},"products":["markdown-pdf"],"published":"2018-07-20","related":[{"cvss_score":8.2,"headline":"markdown-pdf 11.0.0 - Local File Read via Server Side XSS","id":"CVE-2023-0835","kev_date_added":null,"published":"2023-04-04"}],"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":"An attacker can exploit a path traversal vulnerability in the markdown-pdf library to read arbitrary local files from the server.","url":"https://insights.sbomify.com/CVE-2018-3770/"}
