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-2020-2299 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:active-directory (Maven): affected from 1.44; fixed in 2.16.1\n- org.jenkins-ci.plugins:active-directory (Maven): affected from 1.44; 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-2020-2299/ (Markdown: https://insights.sbomify.com/CVE-2020-2299/index.md)","id":"CVE-2020-2299","markdown":"https://insights.sbomify.com/CVE-2020-2299/index.md","name":"CVE-2020-2299","record":{"aliases":["GHSA-rf92-3vjr-w628"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins AD Plugin","requires_auth":"none","summary":"Attackers can log in as any user in Jenkins Active Directory Plugin by using a magic constant password, leading to account takeover.","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 if a magic constant is used as the password.","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 Authentication in Jenkins Active Directory Plugin","id":"CVE-2020-2299","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":4,"n_references":2,"next":{"headline":"Improper Authentication (empty password) in Jenkins Active Directory Plugin","id":"CVE-2020-2300"},"packages":[{"ecosystem":"Maven","fixed":["2.16.1"],"introduced":["1.44"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":null,"source":"GHSA-rf92-3vjr-w628"},{"ecosystem":"Maven","fixed":["2.16.1"],"introduced":["1.44"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":"pkg:maven/org.jenkins-ci.plugins/active-directory","source":"GHSA-rf92-3vjr-w628"},{"ecosystem":"Maven","fixed":["2.20"],"introduced":["2.17"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":null,"source":"GHSA-rf92-3vjr-w628"},{"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-rf92-3vjr-w628"}],"prev":{"headline":"XXE vulnerability in Jenkins Nerrvana Plugin","id":"CVE-2020-2298"},"products":["Jenkins Active Directory Plugin"],"published":"2020-11-04","related":[{"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":9.8,"headline":"Authentication cache in Active Directory Jenkins Plugin allows logging in with any password","id":"CVE-2020-2301","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 log in as any user in Jenkins Active Directory Plugin by using a magic constant password, leading to account takeover.","url":"https://insights.sbomify.com/CVE-2020-2299/"}
