Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-3721 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.main:jenkins-core (Maven): affected all versions; fixed in 1.651.2\n- org.jenkins-ci.main:jenkins-core (Maven): affected all versions; fixed in 1.651.2\n- org.jenkins-ci.main:jenkins-core (Maven): affected from 1.660; fixed in 2.3\n- org.jenkins-ci.main:jenkins-core (Maven): affected from 1.660; fixed in 2.3\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-2016-3721/ (Markdown: https://insights.sbomify.com/CVE-2016-3721/index.md)","id":"CVE-2016-3721","markdown":"https://insights.sbomify.com/CVE-2016-3721/index.md","name":"CVE-2016-3721","record":{"aliases":["GHSA-qf2h-h3xq-j93j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins CI server","requires_auth":"low_privilege","summary":"Authenticated users can inject build parameters into the environment, potentially leading to arbitrary code execution on the Jenkins server.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"jenkins","vendor":"jenkins"},{"product":"openshift","vendor":"redhat"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-17","name":null}],"description":"Jenkins before 2.3 and LTS before 1.651.2 might allow remote authenticated users to inject arbitrary build parameters into the build environment via environment variables.","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":"Jenkins allows Remote Users to Inject Build Parameters","id":"CVE-2016-3721","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"jenkins:jenkins","products":["jenkins:jenkins","redhat:openshift"],"type":"code_injection","year":"2016"},"n_packages":4,"n_references":6,"next":{"headline":"Incorrect Authorization in Jenkins Core","id":"CVE-2016-3722"},"packages":[{"ecosystem":"Maven","fixed":["1.651.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":null,"source":"GHSA-qf2h-h3xq-j93j"},{"ecosystem":"Maven","fixed":["1.651.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":"pkg:maven/org.jenkins-ci.main/jenkins-core","source":"GHSA-qf2h-h3xq-j93j"},{"ecosystem":"Maven","fixed":["2.3"],"introduced":["1.660"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":null,"source":"GHSA-qf2h-h3xq-j93j"},{"ecosystem":"Maven","fixed":["2.3"],"introduced":["1.660"],"last_affected":[],"package":"org.jenkins-ci.main:jenkins-core","purl":"pkg:maven/org.jenkins-ci.main/jenkins-core","source":"GHSA-qf2h-h3xq-j93j"}],"prev":{"headline":"jackson-dataformat-xml vulnerable to XML external entity (XXE)","id":"CVE-2016-3720"},"products":["n/a"],"published":"2016-05-17","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":9.8,"headline":"Jenkins Remote Code Execution","id":"CVE-2017-1000353","kev_date_added":"2025-10-02","published":"2018-01-29"},{"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Authenticated users can inject build parameters into the environment, potentially leading to arbitrary code execution on the Jenkins server.","url":"https://insights.sbomify.com/CVE-2016-3721/"}
