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-2020-2301 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:active-directory (Maven): affected all versions; fixed in 2.16.1\n- org.jenkins-ci.plugins:active-directory (Maven): affected all versions; fixed in 2.16.1\n- org.jenkins-ci.plugins:active-directory (Maven): affected from 2.17; fixed in 2.20\n- org.jenkins-ci.plugins:active-directory (Maven): affected from 2.17; fixed in 2.20\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-2020-2301/ (Markdown: https://insights.sbomify.com/CVE-2020-2301/index.md)","id":"CVE-2020-2301","markdown":"https://insights.sbomify.com/CVE-2020-2301/index.md","name":"CVE-2020-2301","record":{"aliases":["GHSA-954f-xw44-56r2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Jenkins AD Plugin","requires_auth":"none","summary":"Attackers can bypass authentication and log in as any user in Jenkins Active Directory Plugin when using Windows/ADSI mode with caching enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"active_directory","vendor":"jenkins"}],"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":[],"description":"Jenkins Active Directory Plugin 2.19 and earlier allows attackers to log in as any user with any password while a successful authentication of that user is still in the optional cache when using Windows/ADSI mode.","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":"Authentication cache in Active Directory Jenkins Plugin allows logging in with any password","id":"CVE-2020-2301","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":4,"n_references":1,"next":{"headline":"Missing permission check in Jenkins Active Directory Plugin allows accessing domain health check page","id":"CVE-2020-2302"},"packages":[{"ecosystem":"Maven","fixed":["2.16.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":null,"source":"GHSA-954f-xw44-56r2"},{"ecosystem":"Maven","fixed":["2.16.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":"pkg:maven/org.jenkins-ci.plugins/active-directory","source":"GHSA-954f-xw44-56r2"},{"ecosystem":"Maven","fixed":["2.20"],"introduced":["2.17"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":null,"source":"GHSA-954f-xw44-56r2"},{"ecosystem":"Maven","fixed":["2.20"],"introduced":["2.17"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":"pkg:maven/org.jenkins-ci.plugins/active-directory","source":"GHSA-954f-xw44-56r2"}],"prev":{"headline":"Improper Authentication (empty password) in Jenkins Active Directory Plugin","id":"CVE-2020-2300"},"products":["Jenkins Active Directory Plugin"],"published":"2020-11-04","related":[{"cvss_score":9.8,"headline":"Improper Authentication in Jenkins Active Directory Plugin","id":"CVE-2020-2299","kev_date_added":null,"published":"2020-11-04"},{"cvss_score":9.8,"headline":"Improper Authentication (empty password) in Jenkins Active Directory Plugin","id":"CVE-2020-2300","kev_date_added":null,"published":"2020-11-04"},{"cvss_score":8.1,"headline":"Jenkins Active Directory Plugin did not verify certificate of AD server","id":"CVE-2017-2649","kev_date_added":null,"published":"2018-07-27"},{"cvss_score":7.4,"headline":"Jenkins Active Directory Plugin Improper certificate validation with StartTLS","id":"CVE-2019-1003009","kev_date_added":null,"published":"2019-02-06"},{"cvss_score":6.6,"headline":"Jenkins Active Directory Plugin follows LDAP referrals by default","id":"CVE-2026-48918","kev_date_added":null,"published":"2026-05-27"},{"cvss_score":6.6,"headline":"Jenkins Active Directory Plugin deserializes data from LDAP referrals without validation","id":"CVE-2026-48919","kev_date_added":null,"published":"2026-05-27"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Jenkins project"]},"summary":"Attackers can bypass authentication and log in as any user in Jenkins Active Directory Plugin when using Windows/ADSI mode with caching enabled.","url":"https://insights.sbomify.com/CVE-2020-2301/"}
