An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-21907 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-2022-21907/ (Markdown: https://insights.sbomify.com/CVE-2022-21907/index.md)","id":"CVE-2022-21907","markdown":"https://insights.sbomify.com/CVE-2022-21907/index.md","name":"CVE-2022-21907","record":{"aliases":["GHSA-cgqq-62rg-6vmf"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows HTTP Stack","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Windows systems by exploiting the HTTP Protocol Stack, requiring immediate patching.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10","vendor":"microsoft"},{"product":"windows_11","vendor":"microsoft"},{"product":"windows_server","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"HTTP Protocol Stack Remote Code Execution Vulnerability","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2022-01-11","github_poc":16,"max_poc_stars":359,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-01-17T02:28:50Z","kind":"github_poc","ref":"https://github.com/ZZ-SOCMAP/CVE-2022-21907","stars":359,"title":"HTTP Protocol Stack Remote Code Execution Vulnerability CVE-2022-21907"},{"date":"2022-04-04T10:53:28Z","kind":"github_poc","ref":"https://github.com/polakow/CVE-2022-21907","stars":128,"title":"A REAL DoS exploit for CVE-2022-21907"},{"date":"2022-01-17T15:42:37Z","kind":"github_poc","ref":"https://github.com/p0dalirius/CVE-2022-21907-http.sys","stars":82,"title":"Proof of concept of CVE-2022-21907 Double Free in http.sys driver, triggering a kernel crash on IIS servers"},{"date":"2022-01-23T14:25:12Z","kind":"github_poc","ref":"https://github.com/michelep/CVE-2022-21907-Vulnerability-PoC","stars":28,"title":"CVE-2022-21907 Vulnerability PoC"},{"date":"2022-01-15T20:50:25Z","kind":"github_poc","ref":"https://github.com/mauricelambert/CVE-2022-21907","stars":26,"title":"CVE-2022-21907: detection, protection, exploitation and demonstration.
