An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21698 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:subversion (Maven): affected all versions; fixed in 2.15.1\n- org.jenkins-ci.plugins:subversion (Maven): affected all versions; fixed in 2.15.1\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-2021-21698/ (Markdown: https://insights.sbomify.com/CVE-2021-21698/index.md)","id":"CVE-2021-21698","markdown":"https://insights.sbomify.com/CVE-2021-21698/index.md","name":"CVE-2021-21698","record":{"aliases":["GHSA-q58j-fhj7-j6fg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Subversion Plugin","requires_auth":"none","summary":"An attacker can read arbitrary files on the Jenkins controller by manipulating the subversion key file path from an agent.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"subversion","vendor":"jenkins"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Jenkins Subversion Plugin 2.15.0 and earlier does not restrict the name of a file when looking up a subversion key file on the controller from an agent.","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":"Path traversal vulnerability in Jenkins Subversion Plugin allows reading arbitrary files","id":"CVE-2021-21698","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Stored XSS vulnerability in Jenkins Active Choices Plugin","id":"CVE-2021-21699"},"packages":[{"ecosystem":"Maven","fixed":["2.15.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:subversion","purl":null,"source":"GHSA-q58j-fhj7-j6fg"},{"ecosystem":"Maven","fixed":["2.15.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:subversion","purl":"pkg:maven/org.jenkins-ci.plugins/subversion","source":"GHSA-q58j-fhj7-j6fg"}],"prev":{"headline":"Agent-to-controller access control allows reading/writing most content of build directories in Jenkins","id":"CVE-2021-21697"},"products":["Jenkins Subversion Plugin"],"published":"2021-11-04","related":[{"cvss_score":6.5,"headline":"XXE vulnerability in Jenkins Subversion Plugin","id":"CVE-2020-2304","kev_date_added":null,"published":"2020-11-04"},{"cvss_score":6.5,"headline":"Jenkins Subversion Plugin Cross-Site Request Forgery vulnerability","id":"CVE-2017-1000085","kev_date_added":null,"published":"2017-10-04"},{"cvss_score":5.4,"headline":"Subversion Plugin stored XSS vulnerability","id":"CVE-2020-2111","kev_date_added":null,"published":"2020-02-12"},{"cvss_score":5.3,"headline":"Jenkins Subversion Plugin Incorrect Authorization vulnerability","id":"CVE-2018-1000111","kev_date_added":null,"published":"2018-03-13"}],"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 read arbitrary files on the Jenkins controller by manipulating the subversion key file path from an agent.","url":"https://insights.sbomify.com/CVE-2021-21698/"}
