It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-10743 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/mholt/archiver (Go): affected from 3.0.0; fixed in 3.3.2\n- github.com/mholt/archiver (Go): affected from 3.0.0; fixed in 3.3.2\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-2019-10743/ (Markdown: https://insights.sbomify.com/CVE-2019-10743/index.md)","id":"CVE-2019-10743","markdown":"https://insights.sbomify.com/CVE-2019-10743/index.md","name":"CVE-2019-10743","record":{"aliases":["GHSA-h74j-692g-48mq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Node.js archiving library","requires_auth":"none","summary":"Attackers can exploit path traversal in archiver's unarchive functions to overwrite files outside the target directory, potentially leading to arbitrary code execution.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"archiver","vendor":"archiver_project"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"All versions of archiver allow attacker to perform a Zip Slip attack via the \"unarchive\" functions. It is exploited using a specially crafted zip archive, that holds path traversal filenames. When exploited, a filename in a malicious archive is concatenated to the target extraction directory, which results in the final path ending up outside of the target folder. For instance, a zip may hold a file with a \"../../file.exe\" location and thus break out of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2025-07-06","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-07-06T14:46:31Z","kind":"github_poc","ref":"https://github.com/albisorua/PoC-CVE-2019-10743","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Path Traversal in MHolt Archiver","id":"CVE-2019-10743","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2019"},"n_packages":2,"n_references":3,"next":{"headline":"Prototype Pollution in lodash","id":"CVE-2019-10744"},"packages":[{"ecosystem":"Go","fixed":["3.3.2"],"introduced":["3.0.0"],"last_affected":[],"package":"github.com/mholt/archiver","purl":null,"source":"GHSA-h74j-692g-48mq"},{"ecosystem":"Go","fixed":["3.3.2"],"introduced":["3.0.0"],"last_affected":[],"package":"github.com/mholt/archiver","purl":"pkg:golang/github.com/mholt/archiver","source":"GHSA-h74j-692g-48mq"}],"prev":{"headline":"Denial of Service in axios","id":"CVE-2019-10742"},"products":["archiver"],"published":"2019-10-28","related":[{"cvss_score":5.5,"headline":"Arbitrary File Write via Archive Extraction in mholt/archiver","id":"CVE-2018-1002207","kev_date_added":null,"published":"2018-07-25"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can exploit path traversal in archiver's unarchive functions to overwrite files outside the target directory, potentially leading to arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2019-10743/"}
