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-2020-13953 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tapestry:tapestry-core (Maven): affected from 5.4.0; fixed in 5.6.0\n- org.apache.tapestry:tapestry-core (Maven): affected from 5.4.0; fixed in 5.6.0\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-2020-13953/ (Markdown: https://insights.sbomify.com/CVE-2020-13953/index.md)","id":"CVE-2020-13953","markdown":"https://insights.sbomify.com/CVE-2020-13953/index.md","name":"CVE-2020-13953","record":{"aliases":["GHSA-w9mp-p2wp-2xf7"],"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 download sensitive files from the WEB-INF directory by crafting specific URLs in Apache Tapestry applications.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tapestry","vendor":"apache"}],"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-552","name":"Files or Directories Accessible to External Parties"}],"description":"In Apache Tapestry from 5.4.0 to 5.5.0, crafting specific URLs, an attacker can download files inside the WEB-INF folder of the WAR being run.","ecosystems":["Maven"],"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":"Improper file downloads in Apache Tapestry","id":"CVE-2020-13953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Apache CXF Reflected XSS in the services listing page via the styleSheetPath","id":"CVE-2020-13954"},"packages":[{"ecosystem":"Maven","fixed":["5.6.0"],"introduced":["5.4.0"],"last_affected":[],"package":"org.apache.tapestry:tapestry-core","purl":null,"source":"GHSA-w9mp-p2wp-2xf7"},{"ecosystem":"Maven","fixed":["5.6.0"],"introduced":["5.4.0"],"last_affected":[],"package":"org.apache.tapestry:tapestry-core","purl":"pkg:maven/org.apache.tapestry/tapestry-core","source":"GHSA-w9mp-p2wp-2xf7"}],"prev":{"headline":"Plaintext password leak in Apache Superset","id":"CVE-2020-13952"},"products":["Apache Tapestry"],"published":"2020-09-30","related":[{"cvss_score":9.8,"headline":"Apache Tapestry prior to version 4 (EOL) allows RCE though deserialization of untrusted input","id":"CVE-2022-46366","kev_date_added":null,"published":"2022-12-02"},{"cvss_score":9.8,"headline":"Bypass of the fix for CVE-2019-0195","id":"CVE-2021-27850","kev_date_added":null,"published":"2021-04-15"},{"cvss_score":9.8,"headline":"Deserialization flaw in EOL Tapestry 4.","id":"CVE-2020-17531","kev_date_added":null,"published":"2020-12-08"},{"cvss_score":9.8,"headline":"Deserialization of Untrusted Data in Apache Tapestry","id":"CVE-2019-0195","kev_date_added":null,"published":"2019-09-16"},{"cvss_score":9.8,"headline":"Timing attack on HMAC signature comparison in Apache Tapestry","id":"CVE-2019-10071","kev_date_added":null,"published":"2019-09-16"},{"cvss_score":7.8,"headline":"Apache Tapestry Unsafe Object Storage","id":"CVE-2014-1972","kev_date_added":null,"published":"2015-08-22"},{"cvss_score":7.5,"headline":"Apache Tapestry: Possible classpath file download through URL manipulation","id":"CVE-2026-61899","kev_date_added":null,"published":"2026-08-10"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can download sensitive files from the WEB-INF directory by crafting specific URLs in Apache Tapestry applications.","url":"https://insights.sbomify.com/CVE-2020-13953/"}
