Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2255 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-2020-2255/ (Markdown: https://insights.sbomify.com/CVE-2020-2255/index.md)","id":"CVE-2020-2255","markdown":"https://insights.sbomify.com/CVE-2020-2255/index.md","name":"CVE-2020-2255","record":{"aliases":["GHSA-vc7g-4269-f7hw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Blue Ocean Plugin","requires_auth":"low_privilege","summary":"Attackers with read permissions can connect to arbitrary URLs due to missing permission checks in the Jenkins Blue Ocean Plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"blue_ocean","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing permission check in Jenkins Blue Ocean Plugin 1.23.2 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL.","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":"Missing permission check in Blue Ocean Plugin","id":"CVE-2020-2255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Stored XSS vulnerability in Pipeline Maven Integration Plugin via unescaped display name","id":"CVE-2020-2256"},"packages":[{"ecosystem":"Maven","fixed":["1.23.3"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.blueocean:blueocean","purl":null,"source":"GHSA-vc7g-4269-f7hw"},{"ecosystem":"Maven","fixed":["1.23.3"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.blueocean:blueocean","purl":"pkg:maven/io.jenkins.blueocean/blueocean","source":"GHSA-vc7g-4269-f7hw"}],"prev":{"headline":"Path traversal vulnerability in Blue Ocean Plugin","id":"CVE-2020-2254"},"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":"Path traversal vulnerability in Blue Ocean Plugin","id":"CVE-2020-2254","kev_date_added":null,"published":"2020-09-16"},{"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":"Attackers with read permissions can connect to arbitrary URLs due to missing permission checks in the Jenkins Blue Ocean Plugin.","url":"https://insights.sbomify.com/CVE-2020-2255/"}
