An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-46423 and fix it if it is affected.\n\nWhat it is: CVE-2022-46423 is a high-severity vulnerability in Netgear Wnr2000 Firmware, published on 20 Dec 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-46423 in the wild and no public exploit code.\n\nAffected product: Netgear Wnr2000 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-2022-46423/ (Markdown: https://insights.sbomify.com/CVE-2022-46423/index.md)","id":"CVE-2022-46423","markdown":"https://insights.sbomify.com/CVE-2022-46423/index.md","name":"CVE-2022-46423","record":{"aliases":["GHSA-6662-6w2g-g564"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Netgear router","requires_auth":"none","summary":"Attackers can modify firmware images via MITM to bypass checks, enabling arbitrary code execution or denial of service on Netgear routers.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wnr2000_firmware","vendor":"netgear"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"}],"description":"An exploitable firmware modification vulnerability was discovered on the Netgear WNR2000v1 router.
