It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-1466 and fix it if it is affected.\n\nWhat it is: CVE-2020-1466 is a high-severity denial of service vulnerability in Microsoft Windows Server 2012, published on 17 Aug 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1466 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Server 2012. 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-2020-1466/ (Markdown: https://insights.sbomify.com/CVE-2020-1466/index.md)","id":"CVE-2020-1466","markdown":"https://insights.sbomify.com/CVE-2020-1466/index.md","name":"CVE-2020-1466","record":{"aliases":["GHSA-9fj9-5r8v-mh44"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows RD Gateway","requires_auth":"low_privilege","summary":"An attacker can cause the Windows Remote Desktop Gateway service to stop responding by sending specially crafted RDP requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"A denial of service vulnerability exists in Windows Remote Desktop Gateway (RD Gateway) when an attacker connects to the target system using RDP and sends specially crafted requests.
