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-2016-4431 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.struts:struts-parent (Maven): affected from 2.3.20; fixed in 2.3.29\n- org.apache.struts:struts-parent (Maven): affected from 2.3.20; fixed in 2.3.29\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-2016-4431/ (Markdown: https://insights.sbomify.com/CVE-2016-4431/index.md)","id":"CVE-2016-4431","markdown":"https://insights.sbomify.com/CVE-2016-4431/index.md","name":"CVE-2016-4431","record":{"aliases":["GHSA-vq79-mgpx-2wx4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Remote attackers can bypass access restrictions and conduct redirection attacks in Apache Struts 2 by leveraging a default method.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"struts","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Apache Struts 2 2.3.20 through 2.3.28.1 allows remote attackers to bypass intended access restrictions and conduct redirection attacks by leveraging a default method.","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":"Apache Struts Access Control Redirect","id":"CVE-2016-4431","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:struts","products":["apache:struts"],"type":"open_redirect","year":"2016"},"n_packages":2,"n_references":8,"next":{"headline":"AMQP 0-8, 0-9, 0-91, and 0-10 connection handling in Apache Qpid Java before 6.0.3 might allow remote attackers to bypass authentication","id":"CVE-2016-4432"},"packages":[{"ecosystem":"Maven","fixed":["2.3.29"],"introduced":["2.3.20"],"last_affected":[],"package":"org.apache.struts:struts-parent","purl":null,"source":"GHSA-vq79-mgpx-2wx4"},{"ecosystem":"Maven","fixed":["2.3.29"],"introduced":["2.3.20"],"last_affected":[],"package":"org.apache.struts:struts-parent","purl":"pkg:maven/org.apache.struts/struts-parent","source":"GHSA-vq79-mgpx-2wx4"}],"prev":{"headline":"Apache Struts CSRF Vulnerability","id":"CVE-2016-4430"},"products":["n/a"],"published":"2016-07-04","related":[{"cvss_score":9.8,"headline":"Apache Struts Remote Code Execution","id":"CVE-2020-17530","kev_date_added":"2021-11-03","published":"2020-12-11"},{"cvss_score":9.8,"headline":"Apache Struts 1 Improper Input Validation","id":"CVE-2017-9791","kev_date_added":"2022-02-10","published":"2017-07-10"},{"cvss_score":9.8,"headline":"Apache Struts Remote Code Execution","id":"CVE-2017-5638","kev_date_added":"2021-11-03","published":"2017-03-11"},{"cvss_score":9.8,"headline":"Apache Struts 2 Improper Input Validation","id":"CVE-2012-0391","kev_date_added":"2022-01-21","published":"2012-01-08"},{"cvss_score":8.1,"headline":"Apache Struts Remote Code Execution","id":"CVE-2018-11776","kev_date_added":"2021-11-03","published":"2018-08-22"},{"cvss_score":8.1,"headline":"Apache Struts Deserialization of Untrusted Data","id":"CVE-2017-9805","kev_date_added":"2021-11-03","published":"2017-09-15"},{"cvss_score":8.1,"headline":"Apache Struts Command Injection","id":"CVE-2016-3081","kev_date_added":"2026-10-08","published":"2016-04-26"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can bypass access restrictions and conduct redirection attacks in Apache Struts 2 by leveraging a default method.","url":"https://insights.sbomify.com/CVE-2016-4431/"}
