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-2021-21666 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:kiuwanJenkinsPlugin (Maven): affected all versions; fixed in 1.6.1\n- org.jenkins-ci.plugins:kiuwanJenkinsPlugin (Maven): affected all versions; fixed in 1.6.1\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-2021-21666/ (Markdown: https://insights.sbomify.com/CVE-2021-21666/index.md)","id":"CVE-2021-21666","markdown":"https://insights.sbomify.com/CVE-2021-21666/index.md","name":"CVE-2021-21666","record":{"aliases":["GHSA-8h77-3xwr-hqhh"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Kiuwan Plugin","requires_auth":"none","summary":"Reflected XSS in Jenkins Kiuwan Plugin allows attackers to execute arbitrary scripts in victim browsers via unescaped query parameters.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"kiuwan","vendor":"jenkins"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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 Kiuwan Plugin 1.6.0 and earlier does not escape query parameters in an error message for a form validation endpoint, resulting in a reflected cross-site scripting (XSS) vulnerability.","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":"Cross-site scripting in Jenkins Kiuwan Plugin","id":"CVE-2021-21666","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-2021-21667"},"packages":[{"ecosystem":"Maven","fixed":["1.6.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:kiuwanJenkinsPlugin","purl":null,"source":"GHSA-8h77-3xwr-hqhh"},{"ecosystem":"Maven","fixed":["1.6.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:kiuwanJenkinsPlugin","purl":"pkg:maven/org.jenkins-ci.plugins/kiuwanJenkinsPlugin","source":"GHSA-8h77-3xwr-hqhh"}],"prev":{"headline":"CSRF vulnerability in Jenkins XebiaLabs XL Deploy Plugin allows capturing credentials","id":"CVE-2021-21665"},"products":["Jenkins Kiuwan Plugin"],"published":"2021-06-10","related":[],"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":"Reflected XSS in Jenkins Kiuwan Plugin allows attackers to execute arbitrary scripts in victim browsers via unescaped query parameters.","url":"https://insights.sbomify.com/CVE-2021-21666/"}
