{"id":"CVE-2017-1000353","url":"https://www.cyber-defence.io/tools/cve/CVE-2017-1000353","generatedAt":"2026-10-28T22:21:39.193Z","title":"Jenkins Remote Code Execution Vulnerability","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.","published":"2018-01-29T17:29:00.000Z","lastModified":"2026-06-17T00:59:01.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-502"],"affected":["jenkins/jenkins","oracle/communications cloud native core automated test suite"],"epss":{"score":0.99679,"percentile":0.9995,"date":"2026-10-27","history":[]},"kev":{"listed":true,"dateAdded":"2025-10-02","dueDate":"2025-10-23","knownRansomwareCampaignUse":"Unknown","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nhttps://www.jenkins.io/security/advisory/2017-04-26/ ; https://nvd.nist.gov/vuln/detail/CVE-2017-1000353"},"exploits":{"count":1,"verified":false,"firstPublished":"2017-05-05","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":41965,"kind":"exploit","title":"CloudBees Jenkins 2.32.1 - Java Deserialization","url":"https://www.exploit-db.com/exploits/41965","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/java/dos/41965.txt","file":"exploits/java/dos/41965.txt","published":"2017-05-05","added":"2017-05-05","updated":"2017-05-05","author":"SecuriTeam","type":"dos","platform":"java","port":null,"verified":false,"codes":["CVE-2017-1000353"],"tags":"Denial of Service (DoS)","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://blogs.securiteam.com/index.php/archives/3171"}]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 23 October 2025).
