Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2254 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.jenkins.blueocean:blueocean (Maven): affected all versions; fixed in 1.23.3\n- io.jenkins.blueocean:blueocean (Maven): affected all versions; fixed in 1.23.3\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-2020-2254/ (Markdown: https://insights.sbomify.com/CVE-2020-2254/index.md)","id":"CVE-2020-2254","markdown":"https://insights.sbomify.com/CVE-2020-2254/index.md","name":"CVE-2020-2254","record":{"aliases":["GHSA-vq7j-6pcq-f48p"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Jenkins Blue Ocean Plugin","requires_auth":"low_privilege","summary":"An attacker with job configuration permissions can read arbitrary files on the Jenkins controller if an undocumented feature flag is enabled.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"blue_ocean","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-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Jenkins Blue Ocean Plugin 1.23.2 and earlier provides an undocumented feature flag that, when enabled, allows an attacker with Job/Configure or Job/Create permission to read arbitrary files on the Jenkins controller file system.","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 Blue Ocean Plugin","id":"CVE-2020-2254","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Missing permission check in Blue Ocean Plugin","id":"CVE-2020-2255"},"packages":[{"ecosystem":"Maven","fixed":["1.23.3"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.blueocean:blueocean","purl":null,"source":"GHSA-vq7j-6pcq-f48p"},{"ecosystem":"Maven","fixed":["1.23.3"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.blueocean:blueocean","purl":"pkg:maven/io.jenkins.blueocean/blueocean","source":"GHSA-vq7j-6pcq-f48p"}],"prev":{"headline":"Missing hostname validation in Email Extension Plugin","id":"CVE-2020-2253"},"products":["Jenkins Blue Ocean Plugin"],"published":"2020-09-16","related":[{"cvss_score":8.8,"headline":"Jenkins Blue Ocean Plugin cross-site request forgery vulnerability","id":"CVE-2023-40341","kev_date_added":null,"published":"2023-08-16"},{"cvss_score":8.5,"headline":"Improper Authentication in Jenkins Blue Ocean Plugin","id":"CVE-2017-1000106","kev_date_added":null,"published":"2017-10-04"},{"cvss_score":6.5,"headline":"Insufficiently Protected Credentials in Jenkins Pipeline SCM API for Blue Ocean Plugin","id":"CVE-2022-30952","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":6.5,"headline":"Cross Site Request Forgery in Jenkins Blue Ocean Plugin","id":"CVE-2022-30953","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":6.5,"headline":"Missing permission check in Jenkins Blue Ocean Plugin","id":"CVE-2022-30954","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":6.5,"headline":"Cross-Site Request Forgery in Jenkins Blue Ocean Plugin","id":"CVE-2019-1003012","kev_date_added":null,"published":"2019-02-06"}],"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":"2024-08-04","vendors":["Jenkins project"]},"summary":"An attacker with job configuration permissions can read arbitrary files on the Jenkins controller if an undocumented feature flag is enabled.","url":"https://insights.sbomify.com/CVE-2020-2254/"}
