An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2017-1000353 in the wild since at least 2 Oct 2025.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.main:jenkins-core (Maven): affected all versions; fixed in 2.46.2\n- org.jenkins-ci.main:jenkins-core (Maven): affected all versions; fixed in 2.46.2\n- org.jenkins-ci.main:jenkins-core (Maven): affected from 2.50; fixed in 2.57\n- org.jenkins-ci.main:jenkins-core (Maven): affected from 2.50; fixed in 2.57\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-2017-1000353/ (Markdown: https://insights.sbomify.com/CVE-2017-1000353/index.md)","id":"CVE-2017-1000353","markdown":"https://insights.sbomify.com/CVE-2017-1000353/index.md","name":"CVE-2017-1000353","record":{"aliases":["GHSA-26wc-3wqp-g3rp"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins automation server","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code on Jenkins servers by exploiting a deserialization flaw in the CLI protocol.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jenkins","vendor":"jenkins"},{"product":"communications_cloud_native_core_automated_test_suite","vendor":"oracle"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"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.","ecosystems":["Maven"],"exploits":{"exploitdb":1,"first_seen":"2017-04-26","github_poc":2,"max_poc_stars":57,"metasploit":1,"nuclei":0,"refs":[{"date":"2019-04-12T13:24:26Z","kind":"github_poc","ref":"https://github.com/vulhub/CVE-2017-1000353","stars":57,"title":"jenkins CVE-2017-1000353 POC"},{"date":"2022-10-12T09:30:38Z","kind":"github_poc","ref":"https://github.com/r00t4dm/Jenkins-CVE-2017-1000353","stars":3,"title":null},{"date":"2017-04-26","kind":"metasploit","ref":"exploit/linux/http/jenkins_cli_deserialization","stars":null,"title":"Jenkins CLI Deserialization"},{"date":"2017-05-05","kind":"exploitdb","ref":"41965","stars":null,"title":"CloudBees Jenkins 2.32.1 - Java Deserialization"}],"tier":"exploited"},"has_fix":true,"headline":"Jenkins Remote Code Execution","id":"CVE-2017-1000353","indexable":true,"kev":{"dateAdded":"2025-10-02","dueDate":"2025-10-23","knownRansomwareCampaignUse":"Unknown","product":"Jenkins","requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","vendorProject":"Jenkins","vulnerabilityName":"Jenkins Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":"Maven","product":"jenkins:jenkins","products":["jenkins:jenkins","oracle:communications_cloud_native_core_automated_test_suite"],"type":"deserialization","year":"2017"},"n_packages":4,"n_references":5,"next":{"headline":"Improper Authentication in Jenkins","id":"CVE-2017-1000354"},"packages":[{"ecosystem":"Maven","fixed":["2.46.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":null,"source":"GHSA-26wc-3wqp-g3rp"},{"ecosystem":"Maven","fixed":["2.46.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":"pkg:maven/org.jenkins-ci.main/jenkins-core","source":"GHSA-26wc-3wqp-g3rp"},{"ecosystem":"Maven","fixed":["2.57"],"introduced":["2.50"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":null,"source":"GHSA-26wc-3wqp-g3rp"},{"ecosystem":"Maven","fixed":["2.57"],"introduced":["2.50"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":"pkg:maven/org.jenkins-ci.main/jenkins-core","source":"GHSA-26wc-3wqp-g3rp"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2017-1000257"},"products":["n/a"],"published":"2018-01-29","related":[{"cvss_score":9.8,"headline":"Jenkins Command Line Interface (CLI) Path Traversal","id":"CVE-2024-23897","kev_date_added":"2024-08-19","published":"2024-01-24"},{"cvss_score":9.8,"headline":"Jenkins Stapler Web Framework Deserialization of Untrusted Data","id":"CVE-2018-1000861","kev_date_added":"2022-02-10","published":"2018-12-10"},{"cvss_score":7.5,"headline":"Jenkins User Interface (UI) Information Disclosure","id":"CVE-2015-5317","kev_date_added":"2023-05-12","published":"2015-11-25"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins","id":"CVE-2021-21690","kev_date_added":null,"published":"2021-11-04"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins","id":"CVE-2021-21691","kev_date_added":null,"published":"2021-11-04"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins","id":"CVE-2021-21692","kev_date_added":null,"published":"2021-11-04"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary code on Jenkins servers by exploiting a deserialization flaw in the CLI protocol.","url":"https://insights.sbomify.com/CVE-2017-1000353/"}
