Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21642 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:config-file-provider (Maven): affected all versions; fixed in 3.7.1\n- org.jenkins-ci.plugins:config-file-provider (Maven): affected all versions; fixed in 3.7.1\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-2021-21642/ (Markdown: https://insights.sbomify.com/CVE-2021-21642/index.md)","id":"CVE-2021-21642","markdown":"https://insights.sbomify.com/CVE-2021-21642/index.md","name":"CVE-2021-21642","record":{"aliases":["GHSA-q7xg-hh3q-hc68"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Config File Plugin","requires_auth":"low_privilege","summary":"An attacker can exploit XML external entity vulnerabilities in the Jenkins Config File Provider Plugin to read sensitive files or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"config_file_provider","vendor":"jenkins"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Jenkins Config File Provider Plugin 3.7.0 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.","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":"XML External Entity Reference vulnerability in Jenkins Config File Provider Plugin","id":"CVE-2021-21642","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Incorrect permission checks in Jenkins Config File Provider Plugin allow enumerating credentials IDs","id":"CVE-2021-21643"},"packages":[{"ecosystem":"Maven","fixed":["3.7.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:config-file-provider","purl":null,"source":"GHSA-q7xg-hh3q-hc68"},{"ecosystem":"Maven","fixed":["3.7.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:config-file-provider","purl":"pkg:maven/org.jenkins-ci.plugins/config-file-provider","source":"GHSA-q7xg-hh3q-hc68"}],"prev":{"headline":"CSRF vulnerability in Jenkins promoted builds Plugin","id":"CVE-2021-21641"},"products":["Jenkins Config File Provider Plugin"],"published":"2021-04-21","related":[{"cvss_score":8.1,"headline":"CSRF vulnerability in Config File Provider Plugin","id":"CVE-2018-1000414","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.5,"headline":"Jenkins Config File Provider Plugin improper credential masking vulnerability","id":"CVE-2023-40339","kev_date_added":null,"published":"2023-08-16"},{"cvss_score":6.5,"headline":"Incorrect permission checks in Jenkins Config File Provider Plugin allow enumerating credentials IDs","id":"CVE-2021-21643","kev_date_added":null,"published":"2021-04-21"},{"cvss_score":6.5,"headline":"Improper Privilege Management in Jenkins Config File Provider Plugin","id":"CVE-2017-1000104","kev_date_added":null,"published":"2017-10-04"},{"cvss_score":5.4,"headline":"CSRF vulnerability in Jenkins Config File Provider Plugin allows deleting configuration files","id":"CVE-2021-21644","kev_date_added":null,"published":"2021-04-21"},{"cvss_score":5.4,"headline":"Stored XSS vulnerability in Config File Provider Plugin","id":"CVE-2018-1000413","kev_date_added":null,"published":"2019-01-09"}],"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":"An attacker can exploit XML external entity vulnerabilities in the Jenkins Config File Provider Plugin to read sensitive files or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-21642/"}
