It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-1872 exists.\n\nAffected product: Microsoft Windows Server 2008. 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-2011-1872/ (Markdown: https://insights.sbomify.com/CVE-2011-1872/index.md)","id":"CVE-2011-1872","markdown":"https://insights.sbomify.com/CVE-2011-1872/index.md","name":"CVE-2011-1872","record":{"aliases":["GHSA-w37q-mj57-9rm2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Server Hyper-V","requires_auth":"low_privilege","summary":"Guest OS users can cause a host OS denial of service via malformed VMBus packets in Microsoft Windows Server Hyper-V.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2008","vendor":"microsoft"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Hyper-V in Microsoft Windows Server 2008 Gold, SP2, R2, and R2 SP1 allows guest OS users to cause a denial of service (host OS infinite loop) via malformed machine instructions in a VMBus packet, aka \"VMBus Persistent DoS Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-06-14","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-06-14","kind":"exploitdb","ref":"17401","stars":null,"title":"Microsoft HyperV - Persistent Denial of Service (MS11-047)"}],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2011-1872","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2008","products":["microsoft:windows_server_2008"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":4,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-1873"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-1871"},"products":["n/a"],"published":"2011-06-16","related":[{"cvss_score":10,"headline":"Microsoft Windows DNS Server Remote Code Execution","id":"CVE-2020-1350","kev_date_added":"2021-11-03","published":"2020-07-14"},{"cvss_score":9,"headline":"Microsoft Hyper-V RemoteFX vGPU Remote Code Execution","id":"CVE-2020-1040","kev_date_added":"2021-11-03","published":"2020-07-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-1966","kev_date_added":null,"published":"2011-08-10"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-0239","kev_date_added":null,"published":"2010-02-10"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2010-0240","kev_date_added":null,"published":"2010-02-10"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2010-0241","kev_date_added":null,"published":"2010-02-10"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-2505","kev_date_added":null,"published":"2009-12-09"}],"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":"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":"2024-08-06","vendors":["n/a"]},"summary":"Guest OS users can cause a host OS denial of service via malformed VMBus packets in Microsoft Windows Server Hyper-V.","url":"https://insights.sbomify.com/CVE-2011-1872/"}
