An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2003-0866 exists.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat (Maven): affected from 4.0; fixed in 4.1.0\n- org.apache.tomcat:tomcat (Maven): affected from 4.0; fixed in 4.1.0\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-2003-0866/ (Markdown: https://insights.sbomify.com/CVE-2003-0866/index.md)","id":"CVE-2003-0866","markdown":"https://insights.sbomify.com/CVE-2003-0866/index.md","name":"CVE-2003-0866","record":{"aliases":["DSA-395","GHSA-7wj2-48c4-2684"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Tomcat web server","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Tomcat by sending malformed HTTP requests that block subsequent legitimate requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tomcat","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":[],"description":"The Catalina org.apache.catalina.connector.http package in Tomcat 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service via several requests that do not follow the HTTP protocol, which causes Tomcat to reject later requests.","ecosystems":["Maven"],"exploits":{"exploitdb":1,"first_seen":"2003-10-15","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2003-10-15","kind":"exploitdb","ref":"23245","stars":null,"title":"Apache Tomcat 4.0.x - Non-HTTP Request Denial of Service"}],"tier":"weaponised"},"has_fix":true,"headline":"Apache Tomcat Denial of Service vulnerability in the Catalina package","id":"CVE-2003-0866","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:tomcat","products":["apache:tomcat"],"type":"denial_of_service","year":"2003"},"n_packages":2,"n_references":12,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2003-0868"},"packages":[{"ecosystem":"Maven","fixed":["4.1.0"],"introduced":["4.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-7wj2-48c4-2684"},{"ecosystem":"Maven","fixed":["4.1.0"],"introduced":["4.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-7wj2-48c4-2684"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2003-0865"},"products":["n/a"],"published":"2003-10-17","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":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-08","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in Tomcat by sending malformed HTTP requests that block subsequent legitimate requests.","url":"https://insights.sbomify.com/CVE-2003-0866/"}
