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-2017-1000420 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/syncthing/syncthing (Go): affected all versions up to 0.14.33; no fix listed\n- github.com/syncthing/syncthing (Go): affected all versions up to 0.14.33; no fix listed\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-2017-1000420/ (Markdown: https://insights.sbomify.com/CVE-2017-1000420/index.md)","id":"CVE-2017-1000420","markdown":"https://insights.sbomify.com/CVE-2017-1000420/index.md","name":"CVE-2017-1000420","record":{"aliases":["DEBIAN-CVE-2017-1000420","GHSA-28xp-g7f6-7mhf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Syncthing file sync","requires_auth":"none","summary":"Attackers can exploit symlink traversal in Syncthing to overwrite arbitrary files on the system.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"syncthing","vendor":"syncthing"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Syncthing version 0.14.33 and older is vulnerable to symlink traversal resulting in arbitrary file overwrite","ecosystems":["Go"],"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":"Syncthing vulnerable to symlink traversal and arbitrary file overwrite","id":"CVE-2017-1000420","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2017"},"n_packages":2,"n_references":1,"next":{"headline":"Use after free in n/a","id":"CVE-2017-1000421"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.14.33"],"package":"github.com/syncthing/syncthing","purl":null,"source":"GHSA-28xp-g7f6-7mhf"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.14.33"],"package":"github.com/syncthing/syncthing","purl":"pkg:golang/github.com/syncthing/syncthing","source":"GHSA-28xp-g7f6-7mhf"}],"prev":{"headline":"phpBB Server-Side Request Forgery (SSRF)","id":"CVE-2017-1000419"},"products":["n/a"],"published":"2018-01-02","related":[{"cvss_score":7.5,"headline":"Crash due to malformed relay protocol message","id":"CVE-2021-21404","kev_date_added":null,"published":"2021-04-06"},{"cvss_score":4.6,"headline":"Cross-site Scripting (XSS) in Web GUI in syncthing","id":"CVE-2022-46165","kev_date_added":null,"published":"2023-06-06"}],"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":["n/a"]},"summary":"Attackers can exploit symlink traversal in Syncthing to overwrite arbitrary files on the system.","url":"https://insights.sbomify.com/CVE-2017-1000420/"}
