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-2012-4557 in the wild and no public exploit code.\n\nAffected product: Apache Http Server. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2012-4557/ (Markdown: https://insights.sbomify.com/CVE-2012-4557/index.md)","id":"CVE-2012-4557","markdown":"https://insights.sbomify.com/CVE-2012-4557/index.md","name":"CVE-2012-4557","record":{"aliases":["DEBIAN-CVE-2012-4557","GHSA-9p9q-h6h7-37g9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Remote attackers can cause denial of service in Apache HTTP Server by sending expensive requests that exhaust worker nodes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"http_server","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-399","name":null}],"description":"The mod_proxy_ajp module in the Apache HTTP Server 2.2.12 through 2.2.21 places a worker node into an error state upon detection of a long request-processing time, which allows remote attackers to cause a denial of service (worker consumption) via an expensive request.","ecosystems":[],"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 n/a","id":"CVE-2012-4557","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:http_server","products":["apache:http_server"],"type":"denial_of_service","year":"2012"},"n_packages":0,"n_references":24,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2012-4558"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-4556"},"products":["n/a"],"published":"2012-11-30","related":[{"cvss_score":9.8,"headline":"Apache HTTP Server Path Traversal","id":"CVE-2021-42013","kev_date_added":"2021-11-03","published":"2021-10-07"},{"cvss_score":9.1,"headline":"Apache HTTP Server Improper Escaping of Output","id":"CVE-2024-38475","kev_date_added":"2025-05-01","published":"2024-07-01"},{"cvss_score":9,"headline":"Apache HTTP Server-Side Request Forgery (SSRF)","id":"CVE-2021-40438","kev_date_added":"2021-12-01","published":"2021-09-16"},{"cvss_score":7.8,"headline":"Apache HTTP Server Privilege Escalation","id":"CVE-2019-0211","kev_date_added":"2021-11-03","published":"2019-04-08"},{"cvss_score":7.5,"headline":"Apache HTTP Server Path Traversal","id":"CVE-2021-41773","kev_date_added":"2021-11-03","published":"2021-10-05"},{"cvss_score":10,"headline":"Use after free in n/a","id":"CVE-2010-0425","kev_date_added":null,"published":"2010-03-05"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2005-2700","kev_date_added":null,"published":"2005-09-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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 in Apache HTTP Server by sending expensive requests that exhaust worker nodes.","url":"https://insights.sbomify.com/CVE-2012-4557/"}
