{"cve":"CVE-2017-1000353","nvd":{"published":"2018-01-29T17:29:00.193","modified":"2026-06-17T00:59:00.597","status":"Analyzed","description":"Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an unauthenticated remote code execution. An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java `SignedObject` object to the Jenkins CLI, that would be deserialized using a new `ObjectInputStream`, bypassing the existing blacklist-based protection mechanism. We're fixing this issue by adding `SignedObject` to the blacklist. We're also backporting the new HTTP CLI protocol from Jenkins 2.54 to LTS 2.46.2, and deprecating the remoting-based (i.e. Java serialization) CLI protocol, disabling it by default.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["http://packetstormsecurity.com/files/159266/Jenkins-2.56-CLI-Deserialization-Code-Execution.html","http://www.securityfocus.com/bid/98056","https://jenkins.io/security/advisory/2017-04-26/","https://www.exploit-db.com/exploits/41965/","https://www.oracle.com/security-alerts/cpuapr2022.html"],"products":["jenkins:jenkins","oracle:communications_cloud_native_core_automated_test_suite"],"source":"nvd","synced_at":"2026-10-19T20:48:34.567387330+00:00"},"epss":{"cve":"CVE-2017-1000353","score":0.99679,"percentile":0.99951,"date":"2026-10-31"},"kev":{"cve":"CVE-2017-1000353","date_added":"2025-10-02","due_date":"2025-10-23","vendor":"Jenkins","product":"Jenkins","known_ransomware":false},"osv":[{"id":"GHSA-26wc-3wqp-g3rp","url":"https://osv.dev/vulnerability/GHSA-26wc-3wqp-g3rp","summary":"Deserialization of Untrusted Data in Jenkins","modified":"2025-10-22T19:24:26.961613Z","packages":[{"ecosystem":"Maven","name":"org.jenkins-ci.main:jenkins-core","purl":"pkg:maven/org.jenkins-ci.main/jenkins-core","ranges":[">=2.50 <2.57"],"fixed":["2.57"]},{"ecosystem":"Maven","name":"org.jenkins-ci.main:jenkins-core","purl":"pkg:maven/org.jenkins-ci.main/jenkins-core","ranges":["<2.46.2"],"fixed":["2.46.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
