Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2166 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- de.taimos:pipeline-aws (Maven): affected all versions; fixed in 1.41\n- de.taimos:pipeline-aws (Maven): affected all versions; fixed in 1.41\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-2020-2166/ (Markdown: https://insights.sbomify.com/CVE-2020-2166/index.md)","id":"CVE-2020-2166","markdown":"https://insights.sbomify.com/CVE-2020-2166/index.md","name":"CVE-2020-2166","record":{"aliases":["GHSA-w598-25hm-jqx3"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins AWS plugin","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution via unsafe YAML deserialization in the Jenkins AWS Steps plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"pipeline\\","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-20","name":"Improper Input Validation"}],"description":"Jenkins Pipeline: AWS Steps Plugin 1.40 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 Jenkins Pipeline: AWS Steps Plugin","id":"CVE-2020-2166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"RCE vulnerability in Jenkins OpenShift Pipeline Plugin","id":"CVE-2020-2167"},"packages":[{"ecosystem":"Maven","fixed":["1.41"],"introduced":["0"],"last_affected":[],"package":"de.taimos:pipeline-aws","purl":null,"source":"GHSA-w598-25hm-jqx3"},{"ecosystem":"Maven","fixed":["1.41"],"introduced":["0"],"last_affected":[],"package":"de.taimos:pipeline-aws","purl":"pkg:maven/de.taimos/pipeline-aws","source":"GHSA-w598-25hm-jqx3"}],"prev":{"headline":"Passwords transmitted in plain text by Jenkins Artifactory Plugin","id":"CVE-2020-2165"},"products":["Jenkins Pipeline: AWS Steps Plugin"],"published":"2020-03-25","related":[{"cvss_score":9.9,"headline":"Jenkins Matrix Project Plugin Remote Code Execution","id":"CVE-2019-1003030","kev_date_added":"2022-03-25","published":"2019-03-08"},{"cvss_score":9.9,"headline":"Jenkins Pipeline: Groovy Plugin allows sandbox protection bypass and arbitrary code execution","id":"CVE-2022-43402","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":9.8,"headline":"Sandbox bypass vulnerability in Jenkins Pipeline: Groovy Plugin","id":"CVE-2019-1003041","kev_date_added":null,"published":"2019-03-28"},{"cvss_score":8.8,"headline":"CSRF protection for any URL can be bypassed in Jenkins Pipeline: Input Step Plugin","id":"CVE-2022-43407","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":8.8,"headline":"Improper Neutralization of Special Elements used in an OS Command in Jenkins Pipeline: Groovy Plugin","id":"CVE-2022-25173","kev_date_added":null,"published":"2022-02-15"},{"cvss_score":8.8,"headline":"Improper Neutralization of Special Elements used in an OS Command in Jenkins Pipeline: Shared Groovy Libraries Plugin","id":"CVE-2022-25174","kev_date_added":null,"published":"2022-02-15"},{"cvss_score":8.8,"headline":"Jenkins Pipeline: Multibranch Plugin vulnerable to OS Command Injection","id":"CVE-2022-25175","kev_date_added":null,"published":"2022-02-15"}],"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 can achieve remote code execution via unsafe YAML deserialization in the Jenkins AWS Steps plugin.","url":"https://insights.sbomify.com/CVE-2020-2166/"}
