Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21637 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:tfs (Maven): affected all versions up to 5.157.1; no fix listed\n- org.jenkins-ci.plugins:tfs (Maven): affected all versions up to 5.157.1; no fix listed\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-2021-21637/ (Markdown: https://insights.sbomify.com/CVE-2021-21637/index.md)","id":"CVE-2021-21637","markdown":"https://insights.sbomify.com/CVE-2021-21637/index.md","name":"CVE-2021-21637","record":{"aliases":["GHSA-6364-jx4h-7564"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins TFS Plugin","requires_auth":"low_privilege","summary":"Attackers with read access can exploit missing permission checks to capture stored credentials by connecting to malicious URLs.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"team_foundation_server","vendor":"jenkins"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing permission check in Jenkins Team Foundation Server Plugin 5.157.1 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.","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":false,"headline":"Missing permission check in Jenkins Team Foundation Server Plugin allow capturing credentials","id":"CVE-2021-21637","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"CSRF vulnerability in Jenkins Team Foundation Server Plugin allow capturing credentials","id":"CVE-2021-21638"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.157.1"],"package":"org.jenkins-ci.plugins:tfs","purl":null,"source":"GHSA-6364-jx4h-7564"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.157.1"],"package":"org.jenkins-ci.plugins:tfs","purl":"pkg:maven/org.jenkins-ci.plugins/tfs","source":"GHSA-6364-jx4h-7564"}],"prev":{"headline":"Missing permission check in Jenkins Team Foundation Server Plugin allows enumerating credentials IDs","id":"CVE-2021-21636"},"products":["Jenkins Team Foundation Server Plugin"],"published":"2021-03-30","related":[{"cvss_score":8.8,"headline":"CSRF vulnerability in Jenkins Team Foundation Server Plugin allow capturing credentials","id":"CVE-2021-21638","kev_date_added":null,"published":"2021-03-30"},{"cvss_score":4.3,"headline":"Missing permission check in Jenkins Team Foundation Server Plugin allows enumerating credentials IDs","id":"CVE-2021-21636","kev_date_added":null,"published":"2021-03-30"},{"cvss_score":3.3,"headline":"Credentials stored in plain text by Jenkins tfs Plugin","id":"CVE-2020-2249","kev_date_added":null,"published":"2020-09-01"}],"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 read access can exploit missing permission checks to capture stored credentials by connecting to malicious URLs.","url":"https://insights.sbomify.com/CVE-2021-21637/"}
