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-1999-1291 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Nt. 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-1999-1291/ (Markdown: https://insights.sbomify.com/CVE-1999-1291/index.md)","id":"CVE-1999-1291","markdown":"https://insights.sbomify.com/CVE-1999-1291/index.md","name":"CVE-1999-1291","record":{"aliases":["GHSA-6j2v-9wjh-8j7w"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows TCP/IP stack","requires_auth":"none","summary":"Remote attackers can disrupt network connections by spoofing TCP reset packets using sequence numbers obtained from PSH ACK responses.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"windows_95","vendor":"microsoft"},{"product":"windows_nt","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":[],"description":"TCP/IP implementation in Microsoft Windows 95, Windows NT 4.0, and possibly others, allows remote attackers to reset connections by forcing a reset (RST) via a PSH ACK or other means, obtaining the target's last sequence number from the resulting packet, then spoofing a reset to the target.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-1999-1291","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_nt","products":["microsoft:windows_nt"],"type":"denial_of_service","year":"1999"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-1999-1292"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-1999-1290"},"products":["n/a"],"published":"2001-09-12","related":[{"cvss_score":7.8,"headline":"Information disclosure in n/a","id":"CVE-1999-0387","kev_date_added":null,"published":"2000-07-12"},{"cvss_score":7.6,"headline":"Memory corruption in n/a","id":"CVE-2000-0330","kev_date_added":null,"published":"2000-06-02"},{"cvss_score":7.5,"headline":"Weak cryptography in n/a","id":"CVE-1999-0518","kev_date_added":null,"published":"2000-02-04"},{"cvss_score":7.2,"headline":"Code injection in n/a","id":"CVE-2000-0155","kev_date_added":null,"published":"2000-02-23"},{"cvss_score":6.4,"headline":"Auth bypass in n/a","id":"CVE-2000-0979","kev_date_added":null,"published":"2001-01-22"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-1999-1201","kev_date_added":null,"published":"2004-09-01"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-1999-1105","kev_date_added":null,"published":"2002-03-09"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Remote attackers can disrupt network connections by spoofing TCP reset packets using sequence numbers obtained from PSH ACK responses.","url":"https://insights.sbomify.com/CVE-1999-1291/"}
