Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-2211 and fix it if it is affected.\n\nWhat it is: CVE-2020-2211 is a high-severity unsafe deserialization vulnerability in Jenkins ElasticBox Jenkins Kubernetes CI/CD Plugin, published on 2 Jul 2020. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2211 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.elasticbox.jenkins-ci.plugins:kubernetes-ci (Maven): affected all versions up to 1.3; no fix listed\n- com.elasticbox.jenkins-ci.plugins:kubernetes-ci (Maven): affected all versions up to 1.3; no fix listed\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-2020-2211/ (Markdown: https://insights.sbomify.com/CVE-2020-2211/index.md)","id":"CVE-2020-2211","markdown":"https://insights.sbomify.com/CVE-2020-2211/index.md","name":"CVE-2020-2211","record":{"aliases":["GHSA-9r3h-wm3x-v245"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Kubernetes plugin","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution via unsafe YAML deserialization in the Jenkins ElasticBox Kubernetes CI/CD Plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"kubernetes_ci","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 ElasticBox Jenkins Kubernetes CI/CD Plugin 1.3 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":false,"headline":"RCE vulnerability in ElasticBox Jenkins Kubernetes CI/CD Plugin","id":"CVE-2020-2211","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Secret stored in plain text by Jenkins GitHub Coverage Reporter Plugin","id":"CVE-2020-2212"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.3"],"package":"com.elasticbox.jenkins-ci.plugins:kubernetes-ci","purl":null,"source":"GHSA-9r3h-wm3x-v245"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.3"],"package":"com.elasticbox.jenkins-ci.plugins:kubernetes-ci","purl":"pkg:maven/com.elasticbox.jenkins-ci.plugins/kubernetes-ci","source":"GHSA-9r3h-wm3x-v245"}],"prev":{"headline":"Passwords transmitted in plain text by Jenkins Stash Branch Parameter Plugin","id":"CVE-2020-2210"},"products":["Jenkins ElasticBox Jenkins Kubernetes CI/CD Plugin"],"published":"2020-07-02","related":[{"cvss_score":8.8,"headline":"Jenkins Kubernetes CI/CD Plugin vulnerable to Cross-Site Request Forgery","id":"CVE-2019-10468","kev_date_added":null,"published":"2019-10-23"},{"cvss_score":6.5,"headline":"Jenkins Kubernetes CI/CD Plugin vulnerable to Improper Authorization","id":"CVE-2019-10469","kev_date_added":null,"published":"2019-10-23"},{"cvss_score":6.5,"headline":"Jenkins Kubernetes CI/CD Plugin vulnerable to Credential Enumeration","id":"CVE-2019-10470","kev_date_added":null,"published":"2019-10-23"}],"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 ElasticBox Kubernetes CI/CD Plugin.","url":"https://insights.sbomify.com/CVE-2020-2211/"}
