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-2012-4387 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.struts.xwork:xwork-core (Maven): affected from 2.0.0; fixed in 2.3.4.1\n- org.apache.struts.xwork:xwork-core (Maven): affected from 2.0.0; fixed in 2.3.4.1\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-2012-4387/ (Markdown: https://insights.sbomify.com/CVE-2012-4387/index.md)","id":"CVE-2012-4387","markdown":"https://insights.sbomify.com/CVE-2012-4387/index.md","name":"CVE-2012-4387","record":{"aliases":["GHSA-hrgc-54mv-58gv"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Remote attackers can cause denial of service via CPU exhaustion by sending long parameter names processed as OGNL expressions in Apache Struts.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"struts","vendor":"apache"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"Apache Struts 2.0.0 through 2.3.4 allows remote attackers to cause a denial of service (CPU consumption) via a long parameter name, which is processed as an OGNL expression.","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":"Denial of service in Apache Struts","id":"CVE-2012-4387","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:struts","products":["apache:struts"],"type":"denial_of_service","year":"2012"},"n_packages":2,"n_references":7,"next":{"headline":"Other in n/a","id":"CVE-2012-4388"},"packages":[{"ecosystem":"Maven","fixed":["2.3.4.1"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.struts.xwork:xwork-core","purl":null,"source":"GHSA-hrgc-54mv-58gv"},{"ecosystem":"Maven","fixed":["2.3.4.1"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.struts.xwork:xwork-core","purl":"pkg:maven/org.apache.struts.xwork/xwork-core","source":"GHSA-hrgc-54mv-58gv"}],"prev":{"headline":"Cross-Site Request Forgery in Apache Struts","id":"CVE-2012-4386"},"products":["n/a"],"published":"2012-09-05","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 cause denial of service via CPU exhaustion by sending long parameter names processed as OGNL expressions in Apache Struts.","url":"https://insights.sbomify.com/CVE-2012-4387/"}
