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-2011-1871 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 7. 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-2011-1871/ (Markdown: https://insights.sbomify.com/CVE-2011-1871/index.md)","id":"CVE-2011-1871","markdown":"https://insights.sbomify.com/CVE-2011-1871/index.md","name":"CVE-2011-1871","record":{"aliases":["GHSA-99xj-9xhx-pcp4"],"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 cause a system reboot by sending crafted ICMP messages to the Windows TCP/IP stack.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_7","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_vista","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Tcpip.sys in the TCP/IP stack in Microsoft Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows remote attackers to cause a denial of service (reboot) via a series of crafted ICMP messages, aka \"ICMP Denial of Service Vulnerability.\"","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-2011-1871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_7","products":["microsoft:windows_7","microsoft:windows_server_2008","microsoft:windows_vista"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-1872"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2011-1870"},"products":["n/a"],"published":"2011-08-10","related":[{"cvss_score":9.8,"headline":"Microsoft HTTP.sys Remote Code Execution","id":"CVE-2015-1635","kev_date_added":"2022-02-10","published":"2015-04-14"},{"cvss_score":8.8,"headline":"Microsoft Win32k Privilege Escalation","id":"CVE-2015-2360","kev_date_added":"2022-05-25","published":"2015-06-10"},{"cvss_score":8.8,"headline":"Microsoft Kerberos Key Distribution Center (KDC) Privilege Escalation","id":"CVE-2014-6324","kev_date_added":"2022-03-25","published":"2014-11-18"},{"cvss_score":8.8,"headline":"Microsoft Windows Object Linking \u0026 Embedding (OLE) Automation Array Remote Code Execution","id":"CVE-2014-6332","kev_date_added":"2022-03-25","published":"2014-11-11"},{"cvss_score":8.8,"headline":"Microsoft Windows Remote Code Execution","id":"CVE-2014-4148","kev_date_added":"2022-05-25","published":"2014-10-15"},{"cvss_score":8.8,"headline":"Microsoft Windows Group Policy Preferences Password Privilege Escalation","id":"CVE-2014-1812","kev_date_added":"2021-11-03","published":"2014-05-14"},{"cvss_score":8.8,"headline":"Microsoft Windows Out-of-Bounds Write","id":"CVE-2013-3918","kev_date_added":"2025-10-06","published":"2013-11-12"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a system reboot by sending crafted ICMP messages to the Windows TCP/IP stack.","url":"https://insights.sbomify.com/CVE-2011-1871/"}
