Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2158 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:literate (Maven): affected all versions up to 1.0; no fix listed\n- org.jenkins-ci.plugins:literate (Maven): affected all versions up to 1.0; 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-2020-2158/ (Markdown: https://insights.sbomify.com/CVE-2020-2158/index.md)","id":"CVE-2020-2158","markdown":"https://insights.sbomify.com/CVE-2020-2158/index.md","name":"CVE-2020-2158","record":{"aliases":["GHSA-c329-r874-xc7j"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Literate Plugin","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code via unsafe YAML deserialization in the Jenkins Literate Plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"literate","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 Literate Plugin 1.0 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":"Remote Code Execution vulnerability in Jenkins Literate Plugin","id":"CVE-2020-2158","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"OS command injection in CryptoMove Plugin","id":"CVE-2020-2159"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.0"],"package":"org.jenkins-ci.plugins:literate","purl":null,"source":"GHSA-c329-r874-xc7j"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.0"],"package":"org.jenkins-ci.plugins:literate","purl":"pkg:maven/org.jenkins-ci.plugins/literate","source":"GHSA-c329-r874-xc7j"}],"prev":{"headline":"Credentials transmitted in plain text by Skytap Cloud CI Plugin","id":"CVE-2020-2157"},"products":["Jenkins Literate Plugin"],"published":"2020-03-09","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 via unsafe YAML deserialization in the Jenkins Literate Plugin.","url":"https://insights.sbomify.com/CVE-2020-2158/"}
