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-2019-17640 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.vertx:vertx-web (Maven): affected from 3.0.0; fixed in 3.9.4\n- io.vertx:vertx-web (Maven): affected from 3.0.0; fixed in 3.9.4\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-2019-17640/ (Markdown: https://insights.sbomify.com/CVE-2019-17640/index.md)","id":"CVE-2019-17640","markdown":"https://insights.sbomify.com/CVE-2019-17640/index.md","name":"CVE-2019-17640","record":{"aliases":["GHSA-vjw7-6gfq-6wf5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Attackers can escape the webroot directory on Windows systems to read files from the current working directory using Eclipse Vert.x StaticHandler.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"vert.x","vendor":"eclipse"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"In Eclipse Vert.x 3.4.x up to 3.9.4, 4.0.0.milestone1, 4.0.0.milestone2, 4.0.0.milestone3, 4.0.0.milestone4, 4.0.0.milestone5, 4.0.0.Beta1, 4.0.0.Beta2, and 4.0.0.Beta3, StaticHandler doesn't correctly processes back slashes on Windows Operating systems, allowing, escape the webroot folder to the current working directory.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2025-08-20","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-08-20T08:07:36Z","kind":"github_poc","ref":"https://github.com/shoucheng3/vert-x3__vertx-web_CVE-2019-17640_3-9-3","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Path Traversal in Eclipse Vert","id":"CVE-2019-17640","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2019"},"n_packages":2,"n_references":6,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2019-17642"},"packages":[{"ecosystem":"Maven","fixed":["3.9.4"],"introduced":["3.0.0"],"last_affected":[],"package":"io.vertx:vertx-web","purl":null,"source":"GHSA-vjw7-6gfq-6wf5"},{"ecosystem":"Maven","fixed":["3.9.4"],"introduced":["3.0.0"],"last_affected":[],"package":"io.vertx:vertx-web","purl":"pkg:maven/io.vertx/vertx-web","source":"GHSA-vjw7-6gfq-6wf5"}],"prev":{"headline":"Memory corruption in Eclipse OpenJ9","id":"CVE-2019-17639"},"products":["Eclipse Vert.x"],"published":"2020-10-15","related":[{"cvss_score":9.8,"headline":"Eclipse Vert.x does not properly neutralize '' (forward slashes) sequences that can resolve to an external location","id":"CVE-2018-12542","kev_date_added":null,"published":"2018-10-10"},{"cvss_score":9.8,"headline":"Moderate severity vulnerability that affects io.vertx:vertx-core","id":"CVE-2018-12544","kev_date_added":null,"published":"2018-10-10"},{"cvss_score":9.2,"headline":"Deserialization in Eclipse Vert.x","id":"CVE-2026-102469","kev_date_added":null,"published":"2026-10-15"},{"cvss_score":8.8,"headline":"High severity vulnerability that affects io.vertx:vertx-web","id":"CVE-2018-12540","kev_date_added":null,"published":"2018-07-12"},{"cvss_score":8.7,"headline":"Denial of service in Eclipse Vert.x","id":"CVE-2026-102461","kev_date_added":null,"published":"2026-10-15"},{"cvss_score":8.7,"headline":"Denial of service in Eclipse Vert.x","id":"CVE-2026-102467","kev_date_added":null,"published":"2026-10-15"}],"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":"2024-08-05","vendors":["The Eclipse Foundation"]},"summary":"Attackers can escape the webroot directory on Windows systems to read files from the current working directory using Eclipse Vert.x StaticHandler.","url":"https://insights.sbomify.com/CVE-2019-17640/"}
