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-2004-0493 exists.\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-2004-0493/ (Markdown: https://insights.sbomify.com/CVE-2004-0493/index.md)","id":"CVE-2004-0493","markdown":"https://insights.sbomify.com/CVE-2004-0493/index.md","name":"CVE-2004-0493","record":{"aliases":["DEBIAN-CVE-2004-0493","GHSA-jc6w-8vm4-hvp8"],"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 via memory exhaustion in Apache HTTP Server by sending long header lines with excessive whitespace.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"http_server","vendor":"apache"},{"product":"converged_communications_server","vendor":"avaya"},{"product":"s8300","vendor":"avaya"},{"product":"s8500","vendor":"avaya"},{"product":"s8700","vendor":"avaya"},{"product":"linux","vendor":"gentoo"},{"product":"http_server","vendor":"ibm"},{"product":"secure_linux","vendor":"trustix"}],"cvss":{"score":6.4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:P","version":"2.0"},"cwes":[],"description":"The ap_get_mime_headers_core function in Apache httpd 2.0.49 allows remote attackers to cause a denial of service (memory exhaustion), and possibly an integer signedness error leading to a heap-based buffer overflow on 64 bit systems, via long header lines with large numbers of space or tab characters.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2004-07-22","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2004-07-22","kind":"exploitdb","ref":"360","stars":null,"title":"Apache - Arbitrary Long HTTP Headers (Denial of Service)"},{"date":"2004-08-02","kind":"exploitdb","ref":"371","stars":null,"title":"Apache - Arbitrary Long HTTP Headers Denial of Service"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2004-0493","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:http_server","products":["apache:http_server","gentoo:linux","trustix:secure_linux"],"type":"denial_of_service","year":"2004"},"n_packages":0,"n_references":24,"next":{"headline":"Command injection in n/a","id":"CVE-2004-0494"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2004-0492"},"products":["n/a"],"published":"2004-06-30","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":"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 denial of service via memory exhaustion in Apache HTTP Server by sending long header lines with excessive whitespace.","url":"https://insights.sbomify.com/CVE-2004-0493/"}
