Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-1669 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10. 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-2021-1669/ (Markdown: https://insights.sbomify.com/CVE-2021-1669/index.md)","id":"CVE-2021-1669","markdown":"https://insights.sbomify.com/CVE-2021-1669/index.md","name":"CVE-2021-1669","record":{"aliases":["GHSA-cj6v-pvfq-h7pp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Remote Desktop","requires_auth":"low_privilege","summary":"Attackers can bypass security features in Windows Remote Desktop, potentially compromising session integrity on affected Windows and client platforms.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"remote_desktop","vendor":"microsoft"},{"product":"remote_desktop_client","vendor":"microsoft"},{"product":"windows_10","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows Remote Desktop 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 Remote Desktop Security Feature Bypass Vulnerability","id":"CVE-2021-1669","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10","products":["microsoft:windows_10","microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Projected File System FS Filter Driver Information Disclosure Vulnerability","id":"CVE-2021-1670"},"packages":[],"prev":{"headline":"Microsoft DTV-DVD Video Decoder Remote Code Execution Vulnerability","id":"CVE-2021-1668"},"products":["Microsoft Remote Desktop for IoS","Microsoft Remote Desktop for Mac","Remote Desktop client for Windows Desktop","Windows 10 Version 1507","Windows 10 Version 1607","Windows 10 Version 1803","Windows 10 Version 1809","Windows 10 Version 1909","Windows 10 Version 2004","Windows 10 Version 20H2","Windows Server 2016","Windows Server 2016 (Server Core installation)","Windows Server 2019","Windows Server version 2004","Windows Server version 20H2","Windows Server, version 1909 (Server Core installation)"],"published":"2021-01-12","related":[{"cvss_score":8.8,"headline":"Remote Desktop Client Remote Code Execution Vulnerability","id":"CVE-2025-29966","kev_date_added":null,"published":"2025-05-13"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-19","vendors":["Microsoft"]},"summary":"Attackers can bypass security features in Windows Remote Desktop, potentially compromising session integrity on affected Windows and client platforms.","url":"https://insights.sbomify.com/CVE-2021-1669/"}
