Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-33745 in the wild and no public exploit code.\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-2021-33745/ (Markdown: https://insights.sbomify.com/CVE-2021-33745/index.md)","id":"CVE-2021-33745","markdown":"https://insights.sbomify.com/CVE-2021-33745/index.md","name":"CVE-2021-33745","record":{"aliases":["GHSA-rw9c-7p8v-5qxg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows DNS Server","requires_auth":"low_privilege","summary":"Attackers can cause a denial of service in Windows DNS Server, requiring administrators to apply vendor patches.","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"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows DNS Server 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":"Windows DNS Server Denial of Service Vulnerability","id":"CVE-2021-33745","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2008","products":["microsoft:windows_server_2008","microsoft:windows_server_2012","microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Windows DNS Server Remote Code Execution Vulnerability","id":"CVE-2021-33746"},"packages":[],"prev":{"headline":"Windows Secure Kernel Mode Security Feature Bypass Vulnerability","id":"CVE-2021-33744"},"products":["Windows Server 2008 R2 Service Pack 1","Windows Server 2008 R2 Service Pack 1 (Server Core installation)","Windows Server 2008 Service Pack 2","Windows Server 2008 Service Pack 2 (Server Core installation)","Windows Server 2012","Windows Server 2012 (Server Core installation)","Windows Server 2012 R2","Windows Server 2012 R2 (Server Core installation)","Windows Server 2016","Windows Server 2016 (Server Core installation)","Windows Server 2019","Windows Server 2019 (Server Core installation)","Windows Server version 2004","Windows Server version 20H2"],"published":"2021-07-14","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"Attackers can cause a denial of service in Windows DNS Server, requiring administrators to apply vendor patches.","url":"https://insights.sbomify.com/CVE-2021-33745/"}
