It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47880 exists.\n\nAffected product: Realtek Wireless LAN Utility. 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-2021-47880/ (Markdown: https://insights.sbomify.com/CVE-2021-47880/index.md)","id":"CVE-2021-47880","markdown":"https://insights.sbomify.com/CVE-2021-47880/index.md","name":"CVE-2021-47880","record":{"aliases":["GHSA-cxv6-8qc3-gf8h"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Realtek Wireless LAN Utility","requires_auth":"low_privilege","summary":"Local attackers can execute arbitrary code with elevated privileges by exploiting an unquoted service path in the Realtek Wireless LAN Utility.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-428","name":"Unquoted Search Path or Element"}],"description":"Realtek Wireless LAN Utility 700.1631 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges.
