Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2189 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.jenkins.plugins:scm-filter-jervis (Maven): affected all versions; fixed in 0.3\n- io.jenkins.plugins:scm-filter-jervis (Maven): affected all versions; fixed in 0.3\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-2020-2189/ (Markdown: https://insights.sbomify.com/CVE-2020-2189/index.md)","id":"CVE-2020-2189","markdown":"https://insights.sbomify.com/CVE-2020-2189/index.md","name":"CVE-2020-2189","record":{"aliases":["GHSA-4hhq-j3xw-wj89"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins SCM Filter Plugin","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code on Jenkins servers via unsafe YAML deserialization in the SCM Filter Jervis Plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"source_code_management_filter_jervis","vendor":"jenkins"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Jenkins SCM Filter Jervis Plugin 0.2.1 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerability.","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":"RCE vulnerability in SCM Filter Jervis Plugin","id":"CVE-2020-2189","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Improper Neutralization of Input During Web Page Generation in Jenkins Script Security Plugin","id":"CVE-2020-2190"},"packages":[{"ecosystem":"Maven","fixed":["0.3"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:scm-filter-jervis","purl":null,"source":"GHSA-4hhq-j3xw-wj89"},{"ecosystem":"Maven","fixed":["0.3"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:scm-filter-jervis","purl":"pkg:maven/io.jenkins.plugins/scm-filter-jervis","source":"GHSA-4hhq-j3xw-wj89"}],"prev":{"headline":"Users with Overall/Read access can enumerate credentials IDs in Amazon EC2 Plugin","id":"CVE-2020-2188"},"products":["Jenkins SCM Filter Jervis Plugin"],"published":"2020-05-06","related":[],"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":"Remote attackers can execute arbitrary code on Jenkins servers via unsafe YAML deserialization in the SCM Filter Jervis Plugin.","url":"https://insights.sbomify.com/CVE-2020-2189/"}
