An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-24456 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:keycloak (Maven): affected all versions; fixed in 2.3.1\n- org.jenkins-ci.plugins:keycloak (Maven): affected all versions; fixed in 2.3.1\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-2023-24456/ (Markdown: https://insights.sbomify.com/CVE-2023-24456/index.md)","id":"CVE-2023-24456","markdown":"https://insights.sbomify.com/CVE-2023-24456/index.md","name":"CVE-2023-24456","record":{"aliases":["GHSA-9963-gmh8-vvm6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Keycloak plugin","requires_auth":"none","summary":"Attackers can hijack user sessions in Jenkins Keycloak Authentication Plugin by exploiting session fixation vulnerabilities.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"keycloak_authentication","vendor":"jenkins"}],"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-384","name":"Session Fixation"}],"description":"Jenkins Keycloak Authentication Plugin 2.3.0 and earlier does not invalidate the previous session on login.","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":"Session fixation vulnerability in Jenkins Keycloak Authentication Plugin","id":"CVE-2023-24456","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":2,"n_references":1,"next":{"headline":"CSRF vulnerability in Jenkins Keycloak Authentication Plugin","id":"CVE-2023-24457"},"packages":[{"ecosystem":"Maven","fixed":["2.3.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:keycloak","purl":null,"source":"GHSA-9963-gmh8-vvm6"},{"ecosystem":"Maven","fixed":["2.3.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:keycloak","purl":"pkg:maven/org.jenkins-ci.plugins/keycloak","source":"GHSA-9963-gmh8-vvm6"}],"prev":{"headline":"Path Traversal in Jenkins visualexpert Plugin","id":"CVE-2023-24455"},"products":["Jenkins Keycloak Authentication Plugin"],"published":"2023-01-24","related":[{"cvss_score":6.5,"headline":"CSRF vulnerability in Jenkins Keycloak Authentication Plugin","id":"CVE-2023-24457","kev_date_added":null,"published":"2023-01-24"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-02","vendors":["Jenkins Project"]},"summary":"Attackers can hijack user sessions in Jenkins Keycloak Authentication Plugin by exploiting session fixation vulnerabilities.","url":"https://insights.sbomify.com/CVE-2023-24456/"}
