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-2011-2013 exists.\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-2011-2013/ (Markdown: https://insights.sbomify.com/CVE-2011-2013/index.md)","id":"CVE-2011-2013","markdown":"https://insights.sbomify.com/CVE-2011-2013/index.md","name":"CVE-2011-2013","record":{"aliases":["GHSA-q323-hhw8-233j"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows TCP/IP stack","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Windows systems by sending crafted UDP packets to closed ports due to an integer overflow in the TCP/IP stack.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-189","name":null},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Integer overflow in the TCP/IP implementation in Microsoft Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows remote attackers to execute arbitrary code by sending a sequence of crafted UDP packets to a closed port, aka \"Reference Counter Overflow Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-11-08","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-11-08","kind":"exploitdb","ref":"36285","stars":null,"title":"Microsoft Windows - TCP/IP Stack Reference Counter Integer Overflow (MS11-083)"}],"tier":"weaponised"},"has_fix":null,"headline":"Integer overflow in n/a","id":"CVE-2011-2013","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":"integer_overflow","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Auth bypass in n/a","id":"CVE-2011-2014"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-2012"},"products":["n/a"],"published":"2011-11-08","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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-17","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code on Windows systems by sending crafted UDP packets to closed ports due to an integer overflow in the TCP/IP stack.","url":"https://insights.sbomify.com/CVE-2011-2013/"}
