An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-1350 in the wild since at least 3 Nov 2021.\n\nAffected product: Microsoft Windows Server 2008. 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-2020-1350/ (Markdown: https://insights.sbomify.com/CVE-2020-1350/index.md)","id":"CVE-2020-1350","markdown":"https://insights.sbomify.com/CVE-2020-1350/index.md","name":"CVE-2020-1350","record":{"aliases":["GHSA-hcmx-443w-mr76"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows DNS Server","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Windows DNS servers by sending specially crafted requests, requiring immediate patching.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":10,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A remote code execution vulnerability exists in Windows Domain Name System servers when they fail to properly handle requests, aka 'Windows DNS Server Remote Code Execution Vulnerability'.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-03-11","github_poc":15,"max_poc_stars":280,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-07-14T19:02:25Z","kind":"github_poc","ref":"https://github.com/ZephrFish/CVE-2020-1350_HoneyPoC","stars":280,"title":"HoneyPoC: Proof-of-Concept (PoC) script to exploit SIGRed (CVE-2020-1350).
