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-2011-0040 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 2003 Server. 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-2011-0040/ (Markdown: https://insights.sbomify.com/CVE-2011-0040/index.md)","id":"CVE-2011-0040","markdown":"https://insights.sbomify.com/CVE-2011-0040/index.md","name":"CVE-2011-0040","record":{"aliases":["GHSA-9w6c-58mr-5mwx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Active Directory","requires_auth":"none","summary":"Remote attackers can cause denial of service or authentication downgrade in Microsoft Active Directory via crafted SPN update requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_2003_server","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":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The server in Microsoft Active Directory on Windows Server 2003 SP2 does not properly handle an update request for a service principal name (SPN), which allows remote attackers to cause a denial of service (authentication downgrade or outage) via a crafted request that triggers name collisions, aka \"Active Directory SPN Validation 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-2011-0040","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_2003_server","products":["microsoft:windows_2003_server"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":8,"next":{"headline":"Integer overflow in n/a","id":"CVE-2011-0041"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2011-0039"},"products":["n/a"],"published":"2011-02-09","related":[{"cvss_score":8.8,"headline":"Microsoft Windows Video ActiveX Control Remote Code Execution","id":"CVE-2008-0015","kev_date_added":"2026-02-17","published":"2009-07-07"},{"cvss_score":7.8,"headline":"Microsoft Win32k Privilege Escalation","id":"CVE-2015-1701","kev_date_added":"2022-03-03","published":"2015-04-21"},{"cvss_score":7.8,"headline":"Microsoft Windows Kernel Privilege Escalation","id":"CVE-2013-5065","kev_date_added":"2022-03-03","published":"2013-11-27"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2011-1268","kev_date_added":null,"published":"2011-06-16"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-1868","kev_date_added":null,"published":"2011-06-16"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-0661","kev_date_added":null,"published":"2011-04-13"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2011-0654","kev_date_added":null,"published":"2011-02-16"}],"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 denial of service or authentication downgrade in Microsoft Active Directory via crafted SPN update requests.","url":"https://insights.sbomify.com/CVE-2011-0040/"}
