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-2012-4534 in the wild and no public exploit code.\n\nAffected product: Apache Tomcat. 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-2012-4534/ (Markdown: https://insights.sbomify.com/CVE-2012-4534/index.md)","id":"CVE-2012-4534","markdown":"https://insights.sbomify.com/CVE-2012-4534/index.md","name":"CVE-2012-4534","record":{"aliases":["GHSA-pxwv-88pv-hh3j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Remote attackers can cause a denial of service via an infinite loop in Apache Tomcat when using NIO with sendfile and HTTPS.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":2.6,"severity":"low","source":"nvd","vector":"AV:N/AC:H/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"org/apache/tomcat/util/net/NioEndpoint.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28, when the NIO connector is used in conjunction with sendfile and HTTPS, allows remote attackers to cause a denial of service (infinite loop) by terminating the connection during the reading of a response.","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-2012-4534","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:tomcat","products":["apache:tomcat"],"type":"denial_of_service","year":"2012"},"n_packages":0,"n_references":21,"next":{"headline":"Denial of service in n/a","id":"CVE-2012-4535"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2012-4533"},"products":["n/a"],"published":"2012-12-19","related":[{"cvss_score":10,"headline":"Apache Tomcat Path Equivalence","id":"CVE-2025-24813","kev_date_added":"2025-04-01","published":"2025-03-10"},{"cvss_score":9.8,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2016-8735","kev_date_added":"2023-05-12","published":"2017-04-06"},{"cvss_score":8.1,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2017-12617","kev_date_added":"2022-03-25","published":"2017-10-03"},{"cvss_score":8.1,"headline":"Apache Tomcat on Windows Remote Code Execution","id":"CVE-2017-12615","kev_date_added":"2022-03-25","published":"2017-09-19"},{"cvss_score":7.5,"headline":"Apache Tomcat Missing Encryption of Sensitive Data","id":"CVE-2026-34486","kev_date_added":"2026-08-04","published":"2026-04-09"},{"cvss_score":9.8,"headline":"Apache Tomcat: HTTP/2 no-authority bypass of strict SNI validation - CVE-2026-32990 fix incomplete","id":"CVE-2026-65637","kev_date_added":null,"published":"2026-08-25"},{"cvss_score":9.8,"headline":"Apache Tomcat: Limited replay attack possible with DIGEST authentication","id":"CVE-2026-65905","kev_date_added":null,"published":"2026-08-25"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-09","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via an infinite loop in Apache Tomcat when using NIO with sendfile and HTTPS.","url":"https://insights.sbomify.com/CVE-2012-4534/"}
