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-2020-36240 in the wild and no public exploit code.\n\nAffected product: Atlassian Crowd. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-36240/ (Markdown: https://insights.sbomify.com/CVE-2020-36240/index.md)","id":"CVE-2020-36240","markdown":"https://insights.sbomify.com/CVE-2020-36240/index.md","name":"CVE-2020-36240","record":{"aliases":["GHSA-23rx-x963-qprq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Crowd","requires_auth":"none","summary":"Unauthenticated attackers can read arbitrary files in WEB-INF and META-INF directories due to incorrect path access checks in Atlassian Crowd.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"crowd","vendor":"atlassian"}],"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":[],"description":"The ResourceDownloadRewriteRule class in Crowd before version 4.0.4, and from version 4.1.0 before 4.1.2 allowed unauthenticated remote attackers to read arbitrary files within WEB-INF and META-INF directories via an incorrect path access check.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path traversal in Crowd","id":"CVE-2020-36240","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-36241"},"packages":[],"prev":{"headline":"Deserialization in Jira Core Data Center","id":"CVE-2020-36239"},"products":["Crowd"],"published":"2021-03-01","related":[{"cvss_score":9.8,"headline":"Atlassian Crowd and Crowd Data Center Remote Code Execution","id":"CVE-2019-11580","kev_date_added":"2021-11-03","published":"2019-06-03"},{"cvss_score":9.8,"headline":"Auth bypass in Crowd Data Center","id":"CVE-2022-43782","kev_date_added":null,"published":"2022-11-17"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2016-6496","kev_date_added":null,"published":"2016-12-09"},{"cvss_score":8.1,"headline":"Auth bypass in Crowd","id":"CVE-2017-18105","kev_date_added":null,"published":"2019-03-29"},{"cvss_score":8.1,"headline":"Auth bypass in Crowd","id":"CVE-2018-20238","kev_date_added":null,"published":"2019-02-13"},{"cvss_score":8,"headline":"Code injection in Crowd Data Center","id":"CVE-2023-22521","kev_date_added":null,"published":"2023-11-21"},{"cvss_score":7.9,"headline":"XML external entity in Crowd Data Center","id":"CVE-2026-21569","kev_date_added":null,"published":"2026-01-28"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Atlassian"]},"summary":"Unauthenticated attackers can read arbitrary files in WEB-INF and META-INF directories due to incorrect path access checks in Atlassian Crowd.","url":"https://insights.sbomify.com/CVE-2020-36240/"}
