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-2020-2146 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- fr.edf.jenkins.plugins:mac (Maven): affected all versions; fixed in 1.2.0\n- fr.edf.jenkins.plugins:mac (Maven): affected all versions; fixed in 1.2.0\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-2020-2146/ (Markdown: https://insights.sbomify.com/CVE-2020-2146/index.md)","id":"CVE-2020-2146","markdown":"https://insights.sbomify.com/CVE-2020-2146/index.md","name":"CVE-2020-2146","record":{"aliases":["GHSA-rv9g-67f7-grq7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Mac Plugin","requires_auth":"none","summary":"Jenkins Mac Plugin fails to validate SSH host keys, allowing man-in-the-middle attacks that could lead to agent compromise.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"mac","vendor":"jenkins"}],"cvss":{"score":7.4,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Jenkins Mac Plugin 1.1.0 and earlier does not validate SSH host keys when connecting agents created by the plugin, enabling man-in-the-middle 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":"Missing SSH host key validation in Mac Plugin","id":"CVE-2020-2146","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"security_feature_bypass","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"CSRF vulnerability in Mac Plugin","id":"CVE-2020-2147"},"packages":[{"ecosystem":"Maven","fixed":["1.2.0"],"introduced":["0"],"last_affected":[],"package":"fr.edf.jenkins.plugins:mac","purl":null,"source":"GHSA-rv9g-67f7-grq7"},{"ecosystem":"Maven","fixed":["1.2.0"],"introduced":["0"],"last_affected":[],"package":"fr.edf.jenkins.plugins:mac","purl":"pkg:maven/fr.edf.jenkins.plugins/mac","source":"GHSA-rv9g-67f7-grq7"}],"prev":{"headline":"Credentials stored in plain text by Zephyr Enterprise Test Management Plugin","id":"CVE-2020-2145"},"products":["Jenkins Mac Plugin"],"published":"2020-03-09","related":[{"cvss_score":4.3,"headline":"CSRF vulnerability in Mac Plugin","id":"CVE-2020-2147","kev_date_added":null,"published":"2020-03-09"},{"cvss_score":4.3,"headline":"Missing permission checks in Mac Plugin","id":"CVE-2020-2148","kev_date_added":null,"published":"2020-03-09"}],"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":"2024-08-04","vendors":["Jenkins project"]},"summary":"Jenkins Mac Plugin fails to validate SSH host keys, allowing man-in-the-middle attacks that could lead to agent compromise.","url":"https://insights.sbomify.com/CVE-2020-2146/"}
