Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-2256 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:pipeline-maven (Maven): affected all versions; fixed in 3.9.3\n- org.jenkins-ci.plugins:pipeline-maven (Maven): affected all versions; fixed in 3.9.3\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-2020-2256/ (Markdown: https://insights.sbomify.com/CVE-2020-2256/index.md)","id":"CVE-2020-2256","markdown":"https://insights.sbomify.com/CVE-2020-2256/index.md","name":"CVE-2020-2256","record":{"aliases":["GHSA-hq2h-9mc3-h6w2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Maven plugin","requires_auth":"low_privilege","summary":"Stored XSS in Jenkins Maven plugin allows attackers with Job/Configure permission to execute scripts via upstream job display names.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"pipeline_maven_integration","vendor":"jenkins"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Jenkins Pipeline Maven Integration Plugin 3.9.2 and earlier does not escape the upstream job's display name shown as part of a build cause, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.","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":"Stored XSS vulnerability in Pipeline Maven Integration Plugin via unescaped display name","id":"CVE-2020-2256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Stored XSS vulnerability in Validating String Parameter Plugin","id":"CVE-2020-2257"},"packages":[{"ecosystem":"Maven","fixed":["3.9.3"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:pipeline-maven","purl":null,"source":"GHSA-hq2h-9mc3-h6w2"},{"ecosystem":"Maven","fixed":["3.9.3"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:pipeline-maven","purl":"pkg:maven/org.jenkins-ci.plugins/pipeline-maven","source":"GHSA-hq2h-9mc3-h6w2"}],"prev":{"headline":"Missing permission check in Blue Ocean Plugin","id":"CVE-2020-2255"},"products":["Jenkins Pipeline Maven Integration Plugin"],"published":"2020-09-16","related":[{"cvss_score":8.1,"headline":"XML External Entity processing vulnerability in Pipeline Maven Integration Jenkins Plugin","id":"CVE-2019-10327","kev_date_added":null,"published":"2019-05-31"},{"cvss_score":6.5,"headline":"Missing permission check in Jenkins Pipeline Maven Integration Plugin allows enumerating credentials IDs","id":"CVE-2020-2233","kev_date_added":null,"published":"2020-08-12"},{"cvss_score":6.5,"headline":"Missing permission check in Jenkins Pipeline Maven Integration Plugin allow capturing credentials","id":"CVE-2020-2234","kev_date_added":null,"published":"2020-08-12"},{"cvss_score":6.5,"headline":"CSRF vulnerability in Jenkins Pipeline Maven Integration Plugin allow capturing credentials","id":"CVE-2020-2235","kev_date_added":null,"published":"2020-08-12"},{"cvss_score":5.3,"headline":"Improper masking of credentials in Jenkins Pipeline Maven Integration Plugin","id":"CVE-2023-41934","kev_date_added":null,"published":"2023-09-06"}],"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":"Stored XSS in Jenkins Maven plugin allows attackers with Job/Configure permission to execute scripts via upstream job display names.","url":"https://insights.sbomify.com/CVE-2020-2256/"}
