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-2021-34977 and fix it if it is affected.\n\nWhat it is: CVE-2021-34977 is a high-severity authentication bypass vulnerability in Netgear R7000 Firmware, published on 13 Jan 2022. 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-2021-34977 in the wild and no public exploit code.\n\nAffected product: Netgear R7000 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-2021-34977/ (Markdown: https://insights.sbomify.com/CVE-2021-34977/index.md)","id":"CVE-2021-34977","markdown":"https://insights.sbomify.com/CVE-2021-34977/index.md","name":"CVE-2021-34977","record":{"aliases":["GHSA-6r85-9phq-3c46"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"none","summary":"Network-adjacent attackers can bypass authentication to reset the admin password on NETGEAR R7000 routers via SOAP requests.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"r7000_firmware","vendor":"netgear"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R7000 1.0.11.116_10.2.100 routers.
