An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43889 in the wild and no public exploit code.\n\nAffected product: Microsoft Defender for IoT. 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-2021-43889/ (Markdown: https://insights.sbomify.com/CVE-2021-43889/index.md)","id":"CVE-2021-43889","markdown":"https://insights.sbomify.com/CVE-2021-43889/index.md","name":"CVE-2021-43889","record":{"aliases":["GHSA-rpx5-2jw7-fmx4"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Defender for IoT","requires_auth":"high_privilege","summary":"Attackers can achieve remote code execution on Microsoft Defender for IoT deployments, requiring immediate patching by security administrators.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"defender_for_iot","vendor":"microsoft"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Microsoft Defender for IoT Remote Code Execution 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":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2021-43889","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Windows AppX Installer Spoofing","id":"CVE-2021-43890"},"packages":[],"prev":{"headline":"Microsoft Defender for IoT Information Disclosure Vulnerability","id":"CVE-2021-43888"},"products":["Microsoft Defender for IoT"],"published":"2021-12-15","related":[{"cvss_score":10,"headline":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2021-42311","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":10,"headline":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2021-42313","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":9.1,"headline":"Microsoft Defender for IoT Elevation of Privilege Vulnerability","id":"CVE-2024-38089","kev_date_added":null,"published":"2024-07-09"},{"cvss_score":9,"headline":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2021-43882","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":8.8,"headline":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2024-21323","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":8.8,"headline":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2024-29053","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":8.8,"headline":"Microsoft Defender for IoT Remote Code Execution Vulnerability","id":"CVE-2021-41365","kev_date_added":null,"published":"2021-12-15"}],"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":"2024-08-04","vendors":["Microsoft"]},"summary":"Attackers can achieve remote code execution on Microsoft Defender for IoT deployments, requiring immediate patching by security administrators.","url":"https://insights.sbomify.com/CVE-2021-43889/"}
