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-2021-21699 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.biouno:uno-choice (Maven): affected all versions; fixed in 2.5.7\n- org.biouno:uno-choice (Maven): affected all versions; fixed in 2.5.7\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-2021-21699/ (Markdown: https://insights.sbomify.com/CVE-2021-21699/index.md)","id":"CVE-2021-21699","markdown":"https://insights.sbomify.com/CVE-2021-21699/index.md","name":"CVE-2021-21699","record":{"aliases":["GHSA-rp4x-h577-chvq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Active Choices Plugin","requires_auth":"low_privilege","summary":"Attackers with Job/Configure permission can inject malicious scripts via unescaped parameter names, leading to stored XSS in Jenkins.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"active_choices","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 Active Choices Plugin 2.5.6 and earlier does not escape the parameter name of reactive parameters and dynamic reference parameters, 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 Jenkins Active Choices Plugin","id":"CVE-2021-21699","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Stored XSS vulnerability in Jenkins Scriptler Plugin","id":"CVE-2021-21700"},"packages":[{"ecosystem":"Maven","fixed":["2.5.7"],"introduced":["0"],"last_affected":[],"package":"org.biouno:uno-choice","purl":null,"source":"GHSA-rp4x-h577-chvq"},{"ecosystem":"Maven","fixed":["2.5.7"],"introduced":["0"],"last_affected":[],"package":"org.biouno:uno-choice","purl":"pkg:maven/org.biouno/uno-choice","source":"GHSA-rp4x-h577-chvq"}],"prev":{"headline":"Path traversal vulnerability in Jenkins Subversion Plugin allows reading arbitrary files","id":"CVE-2021-21698"},"products":["Jenkins Active Choices Plugin"],"published":"2021-11-12","related":[{"cvss_score":5.4,"headline":"Stored XSS vulnerability in Jenkins Active Choices Plugin","id":"CVE-2020-2289","kev_date_added":null,"published":"2020-10-08"},{"cvss_score":5.4,"headline":"Stored XSS vulnerability in Jenkins Active Choices Plugin","id":"CVE-2020-2290","kev_date_added":null,"published":"2020-10-08"},{"cvss_score":5.4,"headline":"Cross-site Scripting in Jenkins Active Choices plugin","id":"CVE-2017-1000386","kev_date_added":null,"published":"2018-01-26"},{"cvss_score":4.6,"headline":"Stored XSS vulnerability in Jenkins Active Choices Plugin","id":"CVE-2021-21616","kev_date_added":null,"published":"2021-02-24"}],"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":"2024-08-03","vendors":["Jenkins project"]},"summary":"Attackers with Job/Configure permission can inject malicious scripts via unescaped parameter names, leading to stored XSS in Jenkins.","url":"https://insights.sbomify.com/CVE-2021-21699/"}
