An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-2303 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 2.20\n- org.jenkins-ci.plugins:active-directory (Maven): affected all versions; 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-2020-2303/ (Markdown: https://insights.sbomify.com/CVE-2020-2303/index.md)","id":"CVE-2020-2303","markdown":"https://insights.sbomify.com/CVE-2020-2303/index.md","name":"CVE-2020-2303","record":{"aliases":["GHSA-2wf5-4mf7-vmh3"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Active Directory Plugin","requires_auth":"none","summary":"Attackers can exploit CSRF to force connection tests to malicious Active Directory servers using attacker-controlled credentials in Jenkins.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"active_directory","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A cross-site request forgery (CSRF) vulnerability in Jenkins Active Directory Plugin 2.19 and earlier allows attackers to perform connection tests, connecting to attacker-specified or previously configured Active Directory servers using attacker-specified credentials.","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":"CSRF vulnerability in Jenkins Active Directory Plugin","id":"CVE-2020-2303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"csrf","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"XXE vulnerability in Jenkins Subversion Plugin","id":"CVE-2020-2304"},"packages":[{"ecosystem":"Maven","fixed":["2.20"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":null,"source":"GHSA-2wf5-4mf7-vmh3"},{"ecosystem":"Maven","fixed":["2.20"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:active-directory","purl":"pkg:maven/org.jenkins-ci.plugins/active-directory","source":"GHSA-2wf5-4mf7-vmh3"}],"prev":{"headline":"Missing permission check in Jenkins Active Directory Plugin allows accessing domain health check page","id":"CVE-2020-2302"},"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":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":"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":["Jenkins project"]},"summary":"Attackers can exploit CSRF to force connection tests to malicious Active Directory servers using attacker-controlled credentials in Jenkins.","url":"https://insights.sbomify.com/CVE-2020-2303/"}
