An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-21193 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-2025-21193/ (Markdown: https://insights.sbomify.com/CVE-2025-21193/index.md)","id":"CVE-2025-21193","markdown":"https://insights.sbomify.com/CVE-2025-21193/index.md","name":"CVE-2025-21193","record":{"aliases":["GHSA-4wgp-9wjx-2m53"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Server AD FS","requires_auth":"none","summary":"Attackers can spoof Active Directory Federation Services requests, potentially bypassing security controls in Windows Server environments.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2022_23h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Active Directory Federation Server Spoofing 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":"Active Directory Federation Server Spoofing Vulnerability","id":"CVE-2025-21193","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2016","products":["microsoft:windows_server_2016","microsoft:windows_server_2019","microsoft:windows_server_2022","microsoft:windows_server_2022_23h2","microsoft:windows_server_2025"],"type":"csrf","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Surface Security Feature Bypass Vulnerability","id":"CVE-2025-21194"},"packages":[],"prev":{"headline":"Windows Local Security Authority (LSA) Elevation of Privilege Vulnerability","id":"CVE-2025-21191"},"products":["Windows Server 2016","Windows Server 2016 (Server Core installation)","Windows Server 2019","Windows Server 2019 (Server Core installation)","Windows Server 2022","Windows Server 2022, 23H2 Edition (Server Core installation)","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2025-01-14","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-09","vendors":["Microsoft"]},"summary":"Attackers can spoof Active Directory Federation Services requests, potentially bypassing security controls in Windows Server environments.","url":"https://insights.sbomify.com/CVE-2025-21193/"}
