An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-2137 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:timestamper (Maven): affected all versions; fixed in 1.11.2\n- org.jenkins-ci.plugins:timestamper (Maven): affected all versions; fixed in 1.11.2\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-2020-2137/ (Markdown: https://insights.sbomify.com/CVE-2020-2137/index.md)","id":"CVE-2020-2137","markdown":"https://insights.sbomify.com/CVE-2020-2137/index.md","name":"CVE-2020-2137","record":{"aliases":["GHSA-6xxf-rwv4-mrjm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Timestamper Plugin","requires_auth":"high_privilege","summary":"Stored XSS in Jenkins Timestamper Plugin allows attackers with admin permissions to execute arbitrary scripts in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"timestamper","vendor":"jenkins"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Jenkins Timestamper Plugin 1.11.1 and earlier does not sanitize HTML formatting of its output, resulting in a stored XSS vulnerability exploitable by attackers with Overall/Administer permission.","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":"Stored XSS vulnerability in Jenkins Timestamper Plugin","id":"CVE-2020-2137","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"XXE vulnerability in Jenkins Cobertura Plugin","id":"CVE-2020-2138"},"packages":[{"ecosystem":"Maven","fixed":["1.11.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:timestamper","purl":null,"source":"GHSA-6xxf-rwv4-mrjm"},{"ecosystem":"Maven","fixed":["1.11.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:timestamper","purl":"pkg:maven/org.jenkins-ci.plugins/timestamper","source":"GHSA-6xxf-rwv4-mrjm"}],"prev":{"headline":"Improper Neutralization of Input During Web Page Generation in Jenkins Git Plugin","id":"CVE-2020-2136"},"products":["Jenkins Timestamper 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":"Stored XSS in Jenkins Timestamper Plugin allows attackers with admin permissions to execute arbitrary scripts in victim browsers.","url":"https://insights.sbomify.com/CVE-2020-2137/"}
