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-2019-20731 and fix it if it is affected.\n\nWhat it is: CVE-2019-20731 is a medium-severity memory corruption vulnerability in Netgear D6220 Firmware, published on 16 Apr 2020. 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-2019-20731 in the wild and no public exploit code.\n\nAffected product: Netgear D6220 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-2019-20731/ (Markdown: https://insights.sbomify.com/CVE-2019-20731/index.md)","id":"CVE-2019-20731","markdown":"https://insights.sbomify.com/CVE-2019-20731/index.md","name":"CVE-2019-20731","record":{"aliases":["GHSA-qqqg-w8xg-6985"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"high_privilege","summary":"An authenticated user can trigger a buffer overflow in various NETGEAR routers, potentially leading to arbitrary code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"d6220_firmware","vendor":"netgear"},{"product":"d6400_firmware","vendor":"netgear"},{"product":"d7000_firmware","vendor":"netgear"},{"product":"d8500_firmware","vendor":"netgear"},{"product":"ex3700_firmware","vendor":"netgear"},{"product":"ex3800_firmware","vendor":"netgear"},{"product":"ex6000_firmware","vendor":"netgear"},{"product":"ex6100_firmware","vendor":"netgear"},{"product":"ex6120_firmware","vendor":"netgear"},{"product":"ex6130_firmware","vendor":"netgear"},{"product":"ex6150_firmware","vendor":"netgear"},{"product":"ex6200_firmware","vendor":"netgear"},{"product":"ex7000_firmware","vendor":"netgear"},{"product":"r6250_firmware","vendor":"netgear"},{"product":"r6300_firmware","vendor":"netgear"},{"product":"r6400_firmware","vendor":"netgear"},{"product":"r6700_firmware","vendor":"netgear"},{"product":"r6900_firmware","vendor":"netgear"},{"product":"r6900p_firmware","vendor":"netgear"},{"product":"r7000_firmware","vendor":"netgear"},{"product":"r7000p_firmware","vendor":"netgear"},{"product":"r7100lg_firmware","vendor":"netgear"},{"product":"r7300dst_firmware","vendor":"netgear"},{"product":"r7900p_firmware","vendor":"netgear"},{"product":"r8000_firmware","vendor":"netgear"},{"product":"r8000p_firmware","vendor":"netgear"},{"product":"r8300_firmware","vendor":"netgear"},{"product":"r8500_firmware","vendor":"netgear"},{"product":"wn2500rp_firmware","vendor":"netgear"},{"product":"wndr3400_firmware","vendor":"netgear"}],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:3.0/AC:L/AV:L/A:L/C:H/I:L/PR:H/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Certain NETGEAR devices are affected by a buffer overflow by an authenticated user.
