An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2015-8103 exists.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.main:cli (Maven): affected all versions; fixed in 1.625.2\n- org.jenkins-ci.main:cli (Maven): affected all versions; fixed in 1.625.2\n- org.jenkins-ci.main:cli (Maven): affected from 1.626; fixed in 1.638\n- org.jenkins-ci.main:cli (Maven): affected from 1.626; fixed in 1.638\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-2015-8103/ (Markdown: https://insights.sbomify.com/CVE-2015-8103/index.md)","id":"CVE-2015-8103","markdown":"https://insights.sbomify.com/CVE-2015-8103/index.md","name":"CVE-2015-8103","record":{"aliases":["GHSA-wfw7-6632-xcv2","MGASA-2016-0137"],"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":"none","summary":"Remote attackers can execute arbitrary code on Jenkins servers by sending crafted serialized Java objects via the CLI subsystem.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jenkins","vendor":"jenkins"},{"product":"openshift_container_platform","vendor":"redhat"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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":"The Jenkins CLI subsystem in Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to execute arbitrary code via a crafted serialized Java object, related to a problematic webapps/ROOT/WEB-INF/lib/commons-collections-*.jar file and the \"Groovy variant in 'ysoserial'\".","ecosystems":["Maven"],"exploits":{"exploitdb":1,"first_seen":"2015-11-06","github_poc":2,"max_poc_stars":0,"metasploit":3,"nuclei":0,"refs":[{"date":"2015-11-06","kind":"metasploit","ref":"exploit/linux/misc/opennms_java_serialize","stars":null,"title":"OpenNMS Java Object Unserialization Remote Code Execution"},{"date":"2015-11-18","kind":"metasploit","ref":"exploit/linux/misc/jenkins_java_deserialize","stars":null,"title":"Jenkins CLI RMI Java Deserialization Vulnerability"},{"date":"2015-12-15","kind":"exploitdb","ref":"38983","stars":null,"title":"Jenkins CLI -
