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-2021-23147 and fix it if it is affected.\n\nWhat it is: CVE-2021-23147 is a medium-severity authentication bypass vulnerability in Netgear R6700 Firmware, published on 30 Dec 2021. 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-2021-23147 in the wild and no public exploit code.\n\nAffected product: Netgear R6700 Firmware. 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-2021-23147/ (Markdown: https://insights.sbomify.com/CVE-2021-23147/index.md)","id":"CVE-2021-23147","markdown":"https://insights.sbomify.com/CVE-2021-23147/index.md","name":"CVE-2021-23147","record":{"aliases":["GHSA-92gj-cjfc-w72m"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Netgear Nighthawk router","requires_auth":"none","summary":"Attackers with physical access can bypass authentication via UART to execute commands as root on Netgear Nighthawk routers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"r6700_firmware","vendor":"netgear"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Netgear Nighthawk R6700 version 1.0.4.120 does not have sufficient protections for the UART console.
