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-1999-0867 exists.\n\nAffected product: Microsoft Internet Information 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-1999-0867/ (Markdown: https://insights.sbomify.com/CVE-1999-0867/index.md)","id":"CVE-1999-0867","markdown":"https://insights.sbomify.com/CVE-1999-0867/index.md","name":"CVE-1999-0867","record":{"aliases":["GHSA-m9hv-pvv3-2735"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft IIS","requires_auth":"none","summary":"An attacker can cause a denial of service in Microsoft IIS by sending a flood of HTTP requests with malformed headers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"commercial_internet_system","vendor":"microsoft"},{"product":"internet_information_server","vendor":"microsoft"},{"product":"site_server","vendor":"microsoft"}],"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-20","name":"Improper Input Validation"}],"description":"Denial of service in IIS 4.0 via a flood of HTTP requests with malformed headers.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"1999-08-11","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"1999-08-11","kind":"exploitdb","ref":"19457","stars":null,"title":"Microsoft Commercial Internet System 2.0/2.5 / IIS 4.0 / Site Server Commerce Edition 3.0 alpha/3.0 - Denial of Service"}],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-1999-0867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:internet_information_server","products":["microsoft:internet_information_server"],"type":"denial_of_service","year":"1999"},"n_packages":0,"n_references":4,"next":{"headline":"Command injection in n/a","id":"CVE-1999-0868"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-1999-0866"},"products":["n/a"],"published":"2000-01-04","related":[{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2000-0053","kev_date_added":null,"published":"2000-04-18"},{"cvss_score":7.5,"headline":"Missing authorization in n/a","id":"CVE-1999-0777","kev_date_added":null,"published":"2000-01-04"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-2000-0246","kev_date_added":null,"published":"2000-06-02"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-1999-0910","kev_date_added":null,"published":"2000-02-04"},{"cvss_score":2.6,"headline":"Race condition in n/a","id":"CVE-1999-0861","kev_date_added":null,"published":"2000-01-04"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"An attacker can cause a denial of service in Microsoft IIS by sending a flood of HTTP requests with malformed headers.","url":"https://insights.sbomify.com/CVE-1999-0867/"}
