Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-33779 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Server 2016. 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-2021-33779/ (Markdown: https://insights.sbomify.com/CVE-2021-33779/index.md)","id":"CVE-2021-33779","markdown":"https://insights.sbomify.com/CVE-2021-33779/index.md","name":"CVE-2021-33779","record":{"aliases":["GHSA-jgpr-7x8j-xjhf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows AD FS","requires_auth":"low_privilege","summary":"Attackers can bypass security features in Windows AD FS, potentially compromising authentication integrity on affected Windows Server installations.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows AD FS Security Feature Bypass 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 AD FS Security Feature Bypass Vulnerability","id":"CVE-2021-33779","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2016","products":["microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Windows DNS Server Remote Code Execution Vulnerability","id":"CVE-2021-33780"},"packages":[],"prev":{"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2021-33778"},"products":["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":9.9,"headline":"Windows Kernel Remote Code Execution Vulnerability","id":"CVE-2021-34458","kev_date_added":null,"published":"2021-07-16"},{"cvss_score":9.8,"headline":"Windows Remote Desktop Licensing Service Remote Code Execution Vulnerability","id":"CVE-2024-38076","kev_date_added":null,"published":"2024-07-09"},{"cvss_score":8.7,"headline":"Windows Hello Security Feature Bypass Vulnerability","id":"CVE-2026-27928","kev_date_added":null,"published":"2026-04-14"},{"cvss_score":8.1,"headline":"Windows Remote Desktop Services Remote Code Execution Vulnerability","id":"CVE-2025-27482","kev_date_added":null,"published":"2025-04-08"},{"cvss_score":8.1,"headline":"Windows Remote Desktop Services Remote Code Execution Vulnerability","id":"CVE-2024-49106","kev_date_added":null,"published":"2024-12-10"},{"cvss_score":8.1,"headline":"Windows Remote Desktop Services Remote Code Execution Vulnerability","id":"CVE-2024-49108","kev_date_added":null,"published":"2024-12-10"},{"cvss_score":8.1,"headline":"Windows Remote Desktop Services Remote Code Execution Vulnerability","id":"CVE-2024-49115","kev_date_added":null,"published":"2024-12-10"}],"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 bypass security features in Windows AD FS, potentially compromising authentication integrity on affected Windows Server installations.","url":"https://insights.sbomify.com/CVE-2021-33779/"}
