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-1999-0077 exists.\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-1999-0077/ (Markdown: https://insights.sbomify.com/CVE-1999-0077/index.md)","id":"CVE-1999-0077","markdown":"https://insights.sbomify.com/CVE-1999-0077/index.md","name":"CVE-1999-0077","record":{"aliases":["GHSA-j2jv-rjg6-95m2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TCP/IP stack","requires_auth":"none","summary":"Attackers can spoof TCP connections due to predictable sequence numbers, bypassing authentication mechanisms in network stacks.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"windows_nt","vendor":"microsoft"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[],"description":"Predictable TCP sequence numbers allow spoofing.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"1999-09-27","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"1999-09-27","kind":"exploitdb","ref":"19522","stars":null,"title":"Linux Kernel 2.2 - Predictable TCP Initial Sequence Number"}],"tier":"weaponised"},"has_fix":null,"headline":"Other in n/a","id":"CVE-1999-0077","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_nt","products":["microsoft:windows_nt"],"type":"other","year":"1999"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in n/a","id":"CVE-1999-0078"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-1999-0076"},"products":["n/a"],"published":"1999-09-29","related":[{"cvss_score":10,"headline":"The DHCP Server service for Microsoft Windows NT 4.0 Server and Terminal Server Edition does not properly validate the length of certain mes","id":"CVE-2004-0900","kev_date_added":null,"published":"2004-12-15"},{"cvss_score":10,"headline":"The default permissions for the RAS Administration key in Windows NT 4.0 allows local users to execute arbitrary commands by changing the va","id":"CVE-2001-0045","kev_date_added":null,"published":"2001-02-02"},{"cvss_score":10,"headline":"Windows NT 4.0 beta allows users to read and delete shares.","id":"CVE-1999-0119","kev_date_added":null,"published":"2000-02-04"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-1999-0226","kev_date_added":null,"published":"2000-02-04"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-1999-0285","kev_date_added":null,"published":"2000-02-04"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-1999-0489","kev_date_added":null,"published":"2000-02-04"},{"cvss_score":10,"headline":"Misconfiguration in n/a","id":"CVE-1999-0560","kev_date_added":null,"published":"2000-02-04"}],"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":"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":"Attackers can spoof TCP connections due to predictable sequence numbers, bypassing authentication mechanisms in network stacks.","url":"https://insights.sbomify.com/CVE-1999-0077/"}
